Description

HACMP 4.3.1 builds on IBM's position as a leader in high-availability clustering technology with new and improved functionality for usability, installability, system administration, and additional hardware support.

Support Added for AIX Fast Connect: HACMP 4.3.1 now supports the AIX Fast Connect application as a highly available resource. AIX Fast Connect enables non-AIX clients, such as Windows 95, Windows 98, Windows NT®, Windows™ for Work Groups, DOS, and OS/2®, to request file and print services from an AIX server. Support for AIX Connections was previously announced in HACMP Version 4.3. The clverify utility is also enhanced to detect errors in the configuration of AIX Fast Connect with HACMP.

Dynamic Reconfiguration Resource Migration: The Dynamic Reconfiguration Resource Migration utility is now accessible through SMIT panels as well as the original command line interface. This utility allows for rotating and cascading resources to be brought online, offline, or moved. The SMIT panels will make this function easier to use.

Swap Adapter: HACMP 4.3.1 is enhanced to allow the swapping of an IP address of an active service or boot adapter to the address of an available, active standby adapter that is on the same node and network. The original adapter then becomes an available standby adapter. This removes the restriction that a node must be powered down in order to remove and replace an adapter that is hot plugged. This functionality is available through SMIT panels.

ATM Hardware Address Takeover: HACMP 4.3.1 now supports hardware address takeover on ATM adapters attached to the same switch. This support is already available for token ring, Ethernet, and FDDI adapters, and alleviates the communications problems that could occur with Adapter swap and IP Address Takeover for ATM adapters. Hardware address takeover is supported for classical IP and ATM LAN emulation. Hardware Address Takeover is limited to adapters connected to the same switch unit.

HAView Resource Support: The HAView function is enhanced to show resource group submaps. The submap displays a symbol for each node in the cluster that participates in the resource group as well as a symbol for each resource defined in the resource group. The Node submap is updated to display a symbol for each resource group that the node participates in.

Redirect HACMP Log Files: HACMP log file paths no longer need to be hard-coded. The pathname of the HACMP log files is now specified through SMIT panels. The location of the following files can be specified:

  • clresmgrd.log
  • clstrmgr.debug
  • cluster.mmdd
  • cl_sm.log
  • cm.log
  • cspoc.log
  • dms_loads.out
  • emuhacmp.out
  • hacmp.out

Emulate Error Log Driven Events: The AIX Error Notification facility allows customers to define procedures to handle errors that may not be handled by HACMP 4.3.1. The ability to emulate these error log driven events is added to aid script developers in testing their scripts without actually having to make the error occur. Errors can be inserted into the AIX error device file (/dev/error) through the use of SMIT panels.

Automated AIX Error Notification Facility: The Automated AIX Error Notification facility is enhanced to detect automatically what configured resources can be associated with an AIX error log event. The default action is to log these events in the hacmp.out file. Customers can develop their own scripts and associate them with these events.

Node-by-Node Migration to HACMP/ES: To assist customers who are planning on migrating from the HAS or CRM features to the ES or ESCRM features respectively, the node-by-node migration function provides the capability of migrating from HACMP 4.3.1 HAS/CRM to HACMP 4.3.1 ES/ESCRM without having to bring the cluster down. To migrate from a previous release of HACMP HAS or CRM feature to HACMP 4.3.1 ES or ESCRM feature, the customer must first migrate to HACMP 4.3.1 HAS or CRM.

C-SPOC Enhancements: C-SPOC is enhanced with the capability to:

  • Make a disk known to all nodes
  • Create new shared or concurrent volume groups
  • Create new file systems on a shared volume group
  • Remove a disk definition
  • Replace a disk in an existing volume group

These capabilities are accessible through SMIT panels.

Online Planning Sheets Sample Program: The online planning sheet sample program provides a convenient method for the customer to execute the planning process for HACMP 4.3.1. At the end of the process, the program provides the capability of generating a shell script containing the configuration commands that match the online planning sheets configuration.

Publications: A new section is added to the HACMP Planning Guide and the HACMP/ES Installation and Administration Guide that provides guidance to application developers who want their application to work well with HACMP 4.3.1. Also, the HACMP/ES Installation and Administration Guide has been split into two volumes.

Additional Hardware Support: HACMP 4.3.1 now supports the following hardware:

  • 7026-H70
  • 9076-50H
  • 9076-55H
  • RS/6000 SP Attachment Adapter (#8396)
  • Advanced SerialRAID Adapter (#6225)

Easy Upgrade and Migration: Node-by-node upgrades (version compatibility) are available from HACMP for AIX Version 4. Cluster configuration and hardware can be expanded or modified without service disruption through the Dynamic Reconfiguration option. Version compatibility and Dynamic Reconfiguration eliminate the most common causes of scheduled cluster downtime.

Product Positioning

HACMP 4.3.1 is a software program that provides highly available application services for RS/6000 uniprocessors, SMPs or nodes of an SP complex. HACMP 4.3.1 detects system failures and handles fallover to a recovery processor gracefully with a minimal loss of end-user time.

One method of delivering high-availability services is the use of redundant disks. HACMP 4.3.1 provides additional levels of availability with Redundant Array of Independent Disk (RAID) subsystems, disk mirroring, or the Recoverable Virtual Shared Disk on the SP because, in addition to disk failures, it protects against network, adapter, system, and user-defined failures.

Another method of achieving higher availability, fault-tolerant solutions use redundant, specialized hardware to provide the protection against system and application failures. While fault-tolerant solutions do not require system restart, they often do require changes to applications for full, fault tolerance support. HACMP 4.3.1 provides high availability without specialized hardware or changes to most applications.

A fault-tolerant system's redundant hardware cannot be used to perform additional application work while checking the health of the system and application. This makes the system's price/performance relatively expensive compared to HACMP 4.3.1, which allows redundant hardware and software resources to be fully utilized. HACMP 4.3.1 also helps protect against scheduled downtimes for maintenance and system upgrades. HACMP 4.3.1 allows you to upgrade software and modify hardware without loss of cluster services.

HACMP 4.3.1 provides loosely coupled multiprocessing services that allow HACMP 4.3.1 to scale workloads. Such configurations, whether "concurrent access" or "partitioned data access," provide the ability to spread a workload across multiple RS/6000 processors, sharing the disk and CPU resource of the clustered processors. The Concurrent Resource Manager feature of HACMP 4.3.1 provides an open API that applications can utilize to provide concurrent access to shared disk.

HACMP 4.3.1 should be considered for SP and RS/6000 customers when running AIX Version 4.3.2, or later.

HACMP 4.2.2 will continue to be supported for customers who have not yet migrated to AIX Version 4.3.2.

HACMP/ES 4.3 provides support for up to 32 nodes in the SP, RS/6000 Server, and mixed SP and RS/6000 environments. In addition, ES provides RS/6000 Cluster Technology Availability Services (RSCT). With its enhanced scalability and offering of RSCT, ES should be the lead product when proposing HACMP 4.3.1 solutions. HACMP/ESCRM should be proposed in concurrent shared-access environments with AIX Version  4.3.2, or later.

Availability of National Languages: This product is a single, worldwide product utilizing AIX Version 4 (V4) internationalization and localization to provide development and usage of global applications for worldwide markets. The product provides the level of National Languages Support (NLS) provided in the prerequisite AIX V4.3.2 operating system except for the following limitations:

  • This product supports translated screens, panels, and messages, but the Program Integrated Information (PII) is available in U.S. English and Japanese with the limitation that HACMP/ES and HACMP/ESCRM are available in U.S. English only.

Technical Information

Specified Operating Environment

Hardware Requirements: HACMP 4.3.1 works with RS/6000 uniprocessors, SMP servers, and SP™ systems in a "no-single-point-of-failure" server configuration. HACMP 4.3.1 supports the RS/6000 models designed for server applications and meet the minimum requirements for internal memory, internal disk, and I/O slots. The following RS/6000 models and their corresponding upgrades are supported in HACMP 4.3.1:

  • PCI Desktop Systems, Models 140, 150, 240, and 260
  • PCI Deskside Systems, Models E20, E30, F30, F40, and F50
  • PCI Rack Systems, Models H10, S70, and S7A
  • Entry Systems, Models 25S, 250, and 25T
  • Compact Server Systems, Models C10 and C20
  • Desktop Systems, Models 370, 380, 390, 397, and 39H
  • Deskside Systems, Models 570, 57F, 580, 58F, 58H, 590, 59H, 591, and 595
  • Rack Systems, Models 98B, 98E, 98F, 990, 99E, 99F, 99J, 99K, R10, R20, R21, R24, R50, R5U, S70, S7A, H50, and H70
  • Symmetric Multiprocessor Server Systems, Models G30, J30, R30, R3U, G40, J40, R40, R4U, J50, R4U, S70, and S7A
  • SP Systems, Models 204, 205, 206, 207 208 209, 20A, 2A4, 2A5, 2A7, 2A8, 2A9, 2AA, 304, 305, 306, 307, 308, 309, 30A, 3A4, 3A5, 3A7, 3A8, 3A9, 3AA, 3B4, 3B5, 3B7, 3B8, 3B9, 3BA, 404, 405, 406, 407, 408, 409, 40A, 500, 50H, 550, and 55H, including the 604 High Nodes, 604E High Nodes, and the Power2 Super Chip (P2SC) nodes

Any supported RS/6000 can be joined with any other supported RS/6000 in an HACMP 4.3.1 configuration. The Models 250 and 25T can be used in the HACMP 4.3.1 server configuration, but due to slot limitations, a "single-point-of-failure" is unavoidable in shared-disk or shared-network resources.

HACMP 4.3.1 executing in a concurrent access configuration requires one of the following devices:

  • IBM 7131 SSA Multi-Storage Tower Model 405 (supports up to eight nodes; no CD-ROMs or tapes can be installed)
  • IBM 7133 SSA Disk Subsystem Models 020, 600, D40 and T40 (supports up to eight nodes)
  • IBM 7135 RAIDiant Array Models 110 and 210 (supports up to four nodes; dual controllers recommended)
  • IBM 7137 Disk Array Subsystem Models 413, 414, 415, 513, 514, or 515 (supports up to four nodes)
  • IBM 2105 Versatile Storage Server (VSS) Models B09 and 100 (supports up to four nodes)

Certain non-IBM RAID systems can operate in concurrent I/O access environments. IBM will not accept Authorized Program Analysis Reports (APARs) if the non-IBM RAID offerings do not work properly with HACMP 4.3.1.

The minimum configuration and sizing of each machine is highly dependent on the user's database package and other applications.

Actual configuration requirements are highly localized according to the required function and performance needs of individual sites. In configuring a cluster, particular attention must be paid to:

  • Fixed-disk capacity and mirroring (Logical Volume Manager (LVM) and database)
  • Slot limitations and their effect on creating a single-point-of-failure
  • Client access to the cluster
  • Other LAN devices (routers, bridges) and their effect on the cluster
  • Replication of I/O adapters/subsystems
  • Replication of power supplies
  • Other network software

Whenever a process takes over resources after a failure, consideration must be given to work partitioning. For example, if processor "A" is expected to take over for failed processor "B" and continue to perform its original duties, "A" must be configured with enough resources to perform the work of both.

SCSI-2 Differential Disk Cabling for HACMP: The cabling configurations in the following tables assume the processors are at the end of the bus (just before each terminator) and the storage devices are connected to the bus between two of the processors.

The first table lists the available y-cables. Y-cables have three legs that are called base, long leg, and short leg. The first table shows what you can connect to each leg. The cables listed under the long leg and short leg columns can be found in the subsequent table under the cable name column except for the terminator, which is supplied with the y-cable.

SSA Disk Cabling for HACMP 4.3.1: HACMP 4.3.1 supports all of the announced SSA cables and Fiber Optics Channel Extenders. Refer to the appropriate system manuals for cabling information.

Software Requirements: HACMP 4.3.1 requires AIX Version 4.3.2 (5765-C34), or later. HACMP 4.3.1 SP configurations require Parallel System Support Programs for AIX, Version 3.1 (5765-D51), or later.

Each processor within a high-availability server complex requires the licensed program HACMP 4.3.1 to be installed. Except during the upgrade process from earlier releases of HACMP Version 4, all processors in the HACMP 4.3.1 server complex must be at the same AIX operating system level, including PTFs and maintenance upgrades.

Some of the devices supported in HACMP 4.3.1 may require a later release level of the AIX operating system; refer to the specific hardware announcement for the AIX release levels required by the hardware.

The HAView facility requires the installation of TME 10™ NetView® for AIX (5697-NVW).

Compatibility: HACMP 4.3.1 (5765-D28) is not compatible with the previous releases of the licensed product:

  • An upgrade from HACMP/6000™ Version 1.2, 2.1, or 3.1 to HACMP 4.3.1 involves reinstalling HACMP on all nodes in the cluster. This means that at some point, the cluster must be brought down; however, with proper planning the downtime can be reduced.
  • An upgrade from HACMP 4.1, 4.2, 4.2.1, or 4.2.2 also involves reinstalling HACMP on all nodes in the cluster; however, the Version  Compatibility function allows you to upgrade the cluster one node at a time, without taking the entire cluster offline.

The Version Compatibility function is intended to ease migration for HACMP 4.1, and 4.2 customers, and is not intended to provide long-term compatibility between versions of the product.

While HACMP 4.3.1 Enhanced Scalability feature does not interoperate with the other HACMP features, its configuration and customization interfaces are identical. Except for the stated limitations, the Enhanced Scalability feature is functionally compatible with the HAS feature.

Limitations: HACMP 4.3.1 is designed to support client users on a LAN using TCP/IP. HACMP monitors and performs IP address switching for the following TCP/IP-based communications adapters on cluster nodes:

  • Token-ring
  • FDDI
  • Ethernet
  • Fibre Channel (not supported on ES)
  • SP Switch
  • ATM
  • ATM LAN Emulation

HACMP does not by itself execute a high-availability function beyond the nodes in an HACMP cluster. Since HACMP 4.3 is highly configurable, it is the customer's responsibility to determine how and to what extent high availability is implemented.

Limitations of the HAS and CRM Features: Supports clusters of up to eight systems.

Limitations of the HANFS for AIX Feature

  • Supports clusters of exactly two systems only.
  • Cannot run the HANFS for AIX feature (#0884) and the other HACMP features (#0882, #0883, #0885, or #0886) in the same cluster — they are mutually exclusive.
  • Cannot install the HANFS for AIX feature (#0884) and the other HACMP features (#0882, #0883, #0885, or #0886) on the same system — they are mutually exclusive.
  • Cannot support:
    • Concurrent access configurations
    • Cluster Node Snapshots, Quick Configurations, Dynamic Reconfiguration, or Cluster Single Point of Control
    • VSM

Limitations of the ES and ESCRM Features

  • ES supports clusters of up to 32 SP nodes or RS/6000 systems.
  • ESCRM supports clusters of up to 8 SP nodes or RS/6000 systems.
  • Target mode SSA is supported (but the forced down function is not supported).
  • VSM is not supported with a cluster greater than eight nodes.
  • Enhanced Scalability cannot execute in the same cluster as the HAS, CRM, or HANFS for AIX features.
  • SOCC and slip networks are not supported.

Environmental Conditions that Affect the Use of HACMP

  • HACMP 4.3.1 supports LAN-attached clients with TCP/IP protocol.
  • HACMP's time to recover from a failure depends, in part, on the amount of time it takes for AIX to detect the failure. Some token-ring failures cannot be detected in fewer than 60 seconds.
  • HACMP 4.3.1 does not support attached terminals using Local Area Transport-B (LAT-B) protocols.
  • Clients most appropriate to an HACMP 4.3.1 environment are ASCII terminals attached via LAN-based Terminal Servers, Xstations, or TCP/IP-based client systems (such as an X-server TCP/IP interface on a PC, UNIX® workstation, or a UNIX server).
  • Cluster nodes must be within the cable-length limitations of the shared disks, so the physical distance between nodes is limited by the total cable length of the shared disk cables.
  • Transparency of a failure and the subsequent recovery to external users or clients is dependent on the HACMP 4.3.1 configuration, the client system, and application protocol design.
  • The AIX JFS does not support concurrent access from multiple nodes; therefore, storage accessed in a concurrent configuration must be in raw logical volumes.
  • Some HACMP command operands should not be used on systems also running NetView or other programs that catch SNMP traps. Refer to HACMP documentation for details on the use of clinfo daemon with such programs.
  • HACMP does not support 802.3 Ethernet.
  • While the version compatibility function will allow HACMP 4.3.1 to co-exist in a cluster with HACMP 4.1, 4.2, 4.2.1, or 4.2.2, this function is intended as a migration aid only. Once the migration is completed, each processor in the server cluster should be at the same AIX and HACMP release levels, including all PTFs.
  • The version compatibility function in HACMP 4.3.1 assumes the customer is using hardware and software components supported in AIX Version 4.3.2.
  • National Language Support is fully enabled in the HAS, CRM, and HANFS for AIX features; message translation is provided for Japanese.

Performance Considerations: HACMP 4.3.1 cluster performance can be measured and reported many ways. In a Mutual takeover/Partitioned Workload Cluster environment, the user's applications and data are spread across two to eight machines in a cluster. Data management and application management can be placed under the control of a single node for efficiency or on each node for performance. In this partitioned environment, minimal interaction between nodes in a cluster derives high efficiency in each node. When a fallover occurs and the backup machine takes over for a failed node, performance is degraded for that period of time when the node is down.

In data sharing, LAN and file system overhead and data contention can reduce CPU efficiency. Where data must be shared, the concurrent access configuration can be utilized, but less efficiently than a single system because distributed locks must be maintained between cluster processors.

Ordering Information

New Licenses

The ordering information for new licenses is unchanged by this announcement.

Refer to Software Announcement 298-363 , dated October 5, 1998, for complete details.

Current Licensees

Current licensees of 5765-D28 who have not paid a media process charge are encouraged to call IBM Direct at 800-426-2255. A 5692-AIX SPO order is mandatory for shipments of program distribution media and publications.

Current licensees of 5765-D28 who have already paid a media process charge are encouraged to order MES updates by calling 800-879-2755. Before you call this number, IBM Software Delivery and Fulfillment (SDF) requires all AIX/6000® licensed programs installed on any RS/6000 hardware be installed for the customer's appropriate hardware and software serial numbers on AAS. If these conditions are met, SDF will enter an order for an MES to ship the release and will process the installation of the MES. The hours of operation are Monday through Friday, 7:00 a.m. to 4:00 p.m. mountain time.

SDF will request the following information from the caller:

  • Verification of customer name and number.
  • Verification of ship-to address (for a permanent address change, the local IBM office must be contacted).
  • Verification of media on which the update will be provided. If update is required on a different media than reflected in the profile and the customer is going to a higher density media than the original media type, SDF will make a permanent change. Examples of changes that SDF will make are going from 4-mm or 8-mm tape to CD.
  • Number of software shipments to be generated.
  • RS/6000 hardware and software systems' serial numbers.
  • Expected shipment/receipt date.
  • Expedited software delivery requests.

The local IBM office is responsible for:

  • Permanent address change
  • New chargeable software order requests
  • Software discontinuance
  • System program order (SPO) consolidations

If SDF is unable to fulfill a request, SDF will refer the customer to an IBM representative.

* PBOTC = Processor-Based One-Time Charge

Delete and add the appropriate feature from the table below under the customer's 5692-AIX record to generate an MES order which will cause media and licensed program hardcopy entitled publications to be shipped on a given date. To ensure publications are shipped feature 3470 must not be on the 5692-AIX record.

Program Upgrade

Refer to Software Announcement 298-363 , dated October 5, 1998, for complete details.

AIX Upgrade Protection Plan: Existing HACMP customers who have subscribed to the Upgrade Protection Plan (5692-ADV) are eligible to receive the mod level updates in this announcement.

For existing HACMP customers to receive the new upgrade, it is necessary to place an MES order under 5692-ADV to delete and then add the same supply feature based on the HACMP component they purchased under their Upgrade Protection contract.

For example, if you want to receive the update for:

  • High Availability Subsystem: delete, then add, feature 0542
  • Resource Manager or Concurrent Access Upgrade: delete, then add feature 0543
  • HANFS: delete, then add feature 0544
  • Enhanced Scalability: delete, then add feature 0545

Customers who want to enroll in AIX Upgrade Protection Plan for the first time for HACMP products can do so by selecting the appropriate price feature numbers as announced in Software Announcement 298-463 , dated December 15, 1998.

The planned availability date for HACMP 4.3.1 under Upgrade Protection is August 13, 1999.

System Program Order (SPO) (5692-AIX): A 5692-AIX SPO is mandatory for shipments of program distribution and publications. The individual licensed program orders (for example, 5765-D28) are for registration and billing purposes only. No shipment occurs under these orders.

To receive shipment of machine-readable materials stacked on CD-ROM requires an SPO (5692-AIX). Billing for the media type selected is generated under the SPO. To prevent additional billing expenses, place only one SPO order per machine.

Select one of the following (5692-AIX) feature numbers for the licensed program hardcopy entitled publications, along with feature # 9001 for asset registration to be shipped on a given date.
