 Because of the security updates in recent product releases, installation and upgrade procedures have changed significantly. To help avoid issues, follow the installation and upgrade procedures in the product documentation. For the latest hardware and software requirements, see technote 1243309. As noted in the system requirements, the guidelines for selecting hardware have changed. You can install IBM Spectrum Protect on any appropriately provisioned and configured hardware on which you can run an operating system that is supported for the IBM Spectrum Protect release.

To install the server, follow the procedure for your operating system:


To upgrade the server, follow the procedures in Upgrading to V8.1. If your system environment includes a storage agent, you must upgrade the storage agent to V8.1.6 when you upgrade the server to V8.1.6. If you do not upgrade the storage agent, you will experience issues when you attempt to restore or retrieve client data by using LAN-free data movement.

After you install or upgrade the server, ensure that you have followed the instructions to prepare the server for database backup operations:

  • AIX.
  • Linux.
  • For Windows operating systems, see the first row of the Limitations and known issues table, below, for instructions.


Restrictions on upgrading the server from V7 to V8

To upgrade an IBM Spectrum Protect server from V7.1.7.200 or later to V8, upgrade the server directly to V8.1.1 or later.

To upgrade an IBM Spectrum Protect server from V7.1.8 or later to V8, upgrade the server directly to V8.1.3 or later.

Updates, limitations, and known problems


Updates, limitations, and known problems are documented in the form of technotes in the Support knowledge base at the Support Portal. As problems are discovered and resolved, IBM Software Support updates the knowledge base. By searching the knowledge base, you can find workarounds or solutions to problems.

Updates

For a list of new product features and updates, see What's new.

The following additional features are new in IBM Spectrum Protect V8.1.6:

  • Take advantage of enhanced performance for tape drives that support logical block protection (LBP). If you use IBM LTO-7 or later drives, or IBM TS1150 or later drives, you can experience improved performance for read and write operations with LBP. You do not have to change system settings to take advantage of this new feature. Actual results will vary, depending on the system environment.
  • Identify, prevent, and resolve issues by using the new servermon component.
    The IBM Spectrum Protect V8.1.6 release includes the new servermon component, which can be enabled for continuous data collection. You can use the collected data to help identify, prevent, and resolve issues in your system environment. In this release, the servermon component is provided as a technical preview on the Linux and Windows operating systems. For details, see technote 0719885.

Limitations and known issues

The following table lists limitations and known issues for this fix pack:

 
Issue Description

In the documentation for IBM Spectrum Protect on Windows systems, the topic Windows: Preparing the database manager for database backup requires an update. When the currently documented procedure is used, the following error message is displayed:

ANR2984E Database backup terminated due to environment or setup issue related to DSMI_CONFIG - DB2 sqlcode -2033 sqlerrmc 406.

 

This issue occurs only on Windows systems. To resolve the issue, configure the client API options file for IBM Db2 by completing the following steps. These instructions also apply if you installed a previous version of the server with a V8.1.6 client.

1. Determine the location of the Db2 instance directory by issuing the following command:
db2set -i database_instance_name db2instprof
where database_instance_name is the name of the database instance.

For example, if tsminst1 is the database instance name, issue the following command:
db2set -i tsminst1 db2instprof

By default, the client options file that you will create in Step 2 is named dsm.opt and is located in a subdirectory that has the same name as the database instance. The subdirectory is located in the Db2 instance directory path that is returned when the previous command is issued.

For example, if the database instance name is tsminst1 and the Db2 instance directory is c:\programdata\ibm\db2\db2tsm1, the client options file will be stored at the following location with the default name dsm.opt:
c:\programdata\ibm\db2\db2tsm1\tsminst1\dsm.opt

Tip: Optionally, you can configure the DSMI_CONFIG environment variable to specify an alternative name and location for the client options file.

2. Create an API client options file that is called dsm.opt with the following contents: *************************************************
nodename $$_TSMDBMGR_$$ commmethod tcpip tcpserveraddr localhost tcpport port_number
where:

  • The nodename parameter specifies the node name that the client API uses to connect to the server during database backup operations. To ensure that the database can be backed up, this value must be $$_TSMDBMGR_$$.
  • The commmethod parameter specifies the communication method that the client API uses to contact the server.
  • The tcpserveraddr parameter specifies the server address that the client API uses to contact the server for database backup operations. To ensure that the database can be backed up, this value must be localhost.
  • The tcpport parameter specifies the port number that the client API uses to contact the server for database backup operations. Enter the same tcpport value that is specified in the dsmserv.opt server options file. By default, the port number is 1500.

 

3. Save the API client options file in the appropriate directory as described in Step 1.

If the servermon component is enabled, a failure of the IBM Spectrum Protect server or the IBM Db2 database might result in memory leakage.

In this release, the servermon component is provided as a technical preview and is disabled by default.

However, if you enable the servermon component, and the server or Db2 stop responding, you might see memory leakage.

If you plan to shut down the IBM Spectrum Protect server, you must stop the servermon process before the server shutdown.

For more information about enabling and using the servermon component, see technote 0719885.

If you run the servermon component, server instrumentation, or both on an IBM Spectrum Protect V8.1.6 server, you might see a degradation in system performance.

In some system environments, performance degradation is observed while instrumentation data is being collected.

If you experience this issue, and you are running the servermon component with instrumentation, but you are not collecting performance data, disable instrumentation. In this way, you can restore system performance.

Client deployment update packages fail to replicate from a hub server to a spoke server.

Client deployment update packages that were downloaded to a repository on a hub server might fail to replicate to a spoke server. The failure occurs when the spoke server is IBM Spectrum Protect V8.1.6 and you added the spoke by using the Add Spoke wizard in the Operations Center. If client deployment replication is failing, the following error is displayed on the Backup-Archive Client Updates page in the Operations Center:

Failed to prepare update packages.

In addition, the following error messages might be displayed in the activity log:

ANR0453W Server to server session refused - no password defined.
ANR0454E Session rejected by server SPOKE816A, reason: 201 - Communication Failure.

To resolve the issue, update the server password for the spoke and hub servers in the server definition by completing the following steps:

1. Use the DSMADMC command to start an administrative client session.
2. In the administrative client, connect to the hub server. Issue the following command on one line:
update server spoke_server serverpassword=spoke_server_password
3. In the administrative client, connect to the spoke server. Issue the following command on one line:
update server hub_server serverpassword=hub_server_password
4. In the Operations Center, verify that errors are no longer displayed on the Backup-Archive Client Updates page.

In the configuration wizard, some fields might be distorted. If you run the configuration wizard (dsmicfgx) by using a Unicode locale (such as EN_US or DE_DE), fields for Secure Sockets Layer (SSL) entries might be distorted. The fields are smaller in height than other fields in the user interface.

No action is required to resolve this issue. You can enter values in the fields, and the values are processed.

Alternatively, to work around the issue, you can run the configuration wizard by using a non-Unicode locale such as en_US or de_DE.

Tip: Ensure that you set the language of the server to the correct locale. By default, the configuration wizard uses the operating system's locale.

For more information, see technote 0720087.
Tape storage is not supported on Linux on Power Systems (little endian) with Ubuntu Server LTS. You can install and run an IBM Spectrum Protect server on a Linux on Power Systems (little endian) operating system with Ubuntu Server 16.04.02 LTS. However, tape storage is not supported.
To use the storage area network (SAN) discovery feature on a Linux on Power Systems (little endian) operating system, you must install a Marvell QLogic Fibre Channel adapter. For instructions, see technote 2017411.
To use the SAN discovery feature on a Linux x86_64 server with the Ubuntu Server LTS operating system, you must install a Marvell QLogic Fibre Channel adapter. For instructions, see technote 2015363.
Restrictions apply to the operations and storage pool types that are supported for network data management protocol (NDMP) operations. Review the restrictions:
  • Data deduplication is supported only with NetApp file servers and only if the file servers do not use SnapMirror to Tape backup operations.
  • Container storage pools are supported only with NetApp file servers and only if the file servers do not use SnapMirror to Tape backup operations.

 

For more information about the operations and storage pool types that are supported for different brands of file servers, see Storage pool types for NDMP operations.
Restrictions apply when you specify the DEFRAG parameter on the MOVE CONTAINER command. To avoid possible issues, do not run the MOVE CONTAINER command with the DEFRAG=YES option during data ingestion, backup, or delete operations.
To use the IBM Spectrum Protect configuration wizard to configure a clustered environment, you must temporarily enable the Microsoft Windows Server Message Block (SMBv1) protocol. After you are finished using the configuration wizard, disable the SMBv1 protocol.
Caching policy for storage systems might cause data corruption. For storage systems that have aggressive caching policies in which data is confirmed as written before it is committed to permanent storage, data corruption can occur if a power outage or other event prevents the write cache from being committed.

The write cache typically has a battery to prevent loss of data from the cache during short power outages. If a power outage occurs and no battery is available, or the battery cache is full, or the length of the power outage exceeds battery capacity, or another event occurs that prevents the write cache from being committed, any data that IBM Spectrum Protect is managing can become corrupted.

This data includes the location of data, the size of the volumes to which data was written, and data deduplication information that links data to multiple objects.

For more information about requirements for committing cached data to permanent storage, see technote 1137676.
Network connection to a NetApp file server becomes unresponsive during a logical interface (LIF) failover. When IBM Spectrum Protect is configured for network data management protocol (NDMP) operations in a NetApp clustered environment, the network connection to the NetApp file server might become unresponsive during backup operations.

You might experience this issue when a LIF failover occurs in the NetApp cluster. IBM Spectrum Protect does not support LIF failovers for NDMP operations.
IBM Tivoli Monitoring for Tivoli Storage Manager is not available in IBM Spectrum Protect V8.1 product releases. The Tivoli Monitoring for Tivoli Storage Manager component is not delivered in IBM Spectrum Protect V8 product releases. Instead, you can monitor your storage environment by using the Operations Center, a web-based user interface. For instructions, see Installing and upgrading the Operations Center.

Tip: In limited lab testing, Tivoli Monitoring for Tivoli Storage Manager V7 was used to monitor an IBM Spectrum Protect V8 server and to generate reports. For instructions about installing and configuring Tivoli Monitoring for Tivoli Storage Manager, see Tivoli Monitoring for Tivoli Storage Manager.

Readme file - IBM Spectrum Protect device support Fix Pack 8.1.6.000

 


You can use various storage devices with IBM Spectrum Protect to meet specific data protection goals.

The following information is for devices that are supported by IBM Spectrum Protect server Fix Pack 8.1.6.000.

Fix history

To view APARs that were resolved in Fix Pack 8.1.6.000, see technote 1994495.



Supported devices

For information about the devices and hardware that you can use with IBM Spectrum Protect, see the support website for your operating system:
New device support

This release does not introduce support for new devices.

Configuring devices

For information about configuring and managing devices, see Configuring storage or the IBM Spectrum Protect Tape Solution Guide.

The following table provides actions that you can take to more efficiently manage your devices and to avoid device configuration issues.
 
Action Description
Ensure that HBAs meet requirements. For best results, connect tape drives and tape libraries to the system on their own host bus adapter (HBA). Do not share the HBA with other device types, such as DISK.
Do not exceed the maximum number of devices that are supported by IBM Spectrum Protect. For information about the maximum number of devices that you can use with IBM Spectrum Protect device drivers on each operating system, see technote 1364225.
Review the support information for SAS device support. Serial Attached SCSI (SAS) devices can be used with some operating system versions and architectures. For information about operating systems versions and architectures for SAS devices, see technote 1396706.
Review requirements for running the IBM Spectrum Protect passthru driver with a non-root user ID on Linux operating systems. For information about how a non-root user ID can use devices with the IBM Spectrum Protect passthru driver on Linux, see technote 1321130.

To ensure that non-root user IDs can use devices that are configured with the IBM Spectrum Protect passthru driver, specify option -g or -a in the device autoconf utility. To add read and write permissions for groups to the SCSI generic driver (sg) device files, specify option -g. To add read and write permissions for all users to the sg device files, specify option -a.
Ensure that libraries meet requirements. IBM Spectrum Protect Extended Edition is required for a library with more than four drives or more than 48 storage slots.

For a library with multiple drives, a drive element address is required for the DEFINE DRIVE and UPDATE DRIVE commands. However, if the library reports drive serial numbers, you can specify ELEMENT=AUTODETECT, and the element address is not required. Alternatively, you can automatically associate a library with its drives by issuing the PERFORM LIBACTION command, and specifying ACTION=DEFINE.
