Problem(Abstract)

Tivoli Storage Manager Server for HP-UX Requirements and Support

Resolving the problem


IBM Tivoli Storage Manager supports both single server and network environments. IBM Tivoli Storage Manager supports single server environments by placing an IBM Tivoli Storage Manager client and server on the same machine. This can be a useful configuration for protecting large file servers, application servers and database servers. Tivoli Storage Manager supports a network environment by allowing IBM Tivoli Storage Manager clients running on over 25 different operating systems to back up their data to an IBM Tivoli Storage Manager server over one of the supported communication protocols.

Minimum Hardware and Software Requirements

Tivoli Storage Manager server V7.1
Hardware A 64-bit Intel Itanium system.
Disk space The following minimum values for disk space:
  • 512 MB for the /var directory
  • 6 GB in the installation directory
  • 2 GB for the /opt directory if you do not create mount points
  • 2 GB for the /tmp directory
  • 300 MB for the /usr directory
  • 2 GB in the home directory
Tip: Expect to use more space for problem determination.
  • 2 GB for the shared resources area

Significant additional disk space is required for database and log files. The size of the database depends on the number of client files to be stored and the method by which the server manages them. The default active log space is 16 GB, the minimum that is needed for most workloads and configurations. Allocate at least three times the active log space for the archive log (48 GB). Ensure that you have sufficient resources if you are using data deduplication or expect a heavy client workload.

For optimal performance and to facilitate I/O, specify at least two equally sized containers or Logical Unit Numbers (LUNs) for the database. See Optimizing Performance for more information about the configuration of directories for the database. In addition, each active log and archive log should have its own container or LUN.

Ensure that you see the capacity planning section for more details about disk space.

Memory The following minimum values for memory:
  • 12 GB.
  • 16 GB if you are using data deduplication.
  • At least 32 GB for heavily used servers. Using 32 GB or more of memory enhances performance of the Tivoli Storage Manager server database inventory.
  • If you plan to run multiple instances, each instance requires the memory listed for one server. Multiply the memory for one server by the number of instances planned for the system.
  • Node replication processing requires additional memory. Use a minimum of 32 GB of memory for node replication without data deduplication. Node replication with data deduplication requires a minimum of 64 GB of memory.
  • When you create the active log, you need at least 64 GB of memory to run replication. If replication and deduplication are both being used, create an active log of 128 GB in size.
Devices A DVD device that is available for the installation process, if you are installing from DVD media.
Operating
system
The HP Itanium system must have operating system 11i v3 (11.31) with the most current maintenance levels installed.
11i v3 with:
  • PHCO_38658 - libc cumulative patch
  • PHSS_37202
  • PHKL_41481
  • PHKL_42035
  • PHKL_42335
  • PHKL_41588
  • PHSS_41496

The latest available service patches for the operating system must be applied. Older levels without patches do not work with the device drivers that Tivoli Storage Manager uses.
Communication protocol A communication method that is installed and activated (shared memory is the default).
Device drivers The Tivoli Storage Manager passthru device driver is used for non-IBM devices. It uses the SCSI passthru interface to communicate with tape drives and tape libraries. The stape device driver is required for tape drives. The schgr device driver is required for tape libraries. The Tivoli Storage Manager device driver package contains device driver tools and ACSLS daemons.

For the IBM® 3590, 3592, or the Ultrium tape library or drives, the IBM device drivers are required. Install the most current device drivers. You can locate IBM driver packages at the Fix Central website: http://www.ibm.com/support/fixcentral/.

Configure the device drivers before you use the Tivoli Storage Manager server with tape devices.

Gunzip utility The gunzip utility must be available on your system before you install or upgrade the Tivoli Storage Manager Version 7 server. Ensure that the gunzip utility is installed and the path to it is set in the PATH environment variable.

Memory
Recommended
  • 12 GB.
  • 16 GB if you are using deduplication.
  • At least 32 GB for heavily used servers. Using 32 GB or more of memory enhances performance of the Tivoli Storage Manager server database inventory.
  • If you plan to run multiple instances, each instance requires the memory listed for one server. Multiply the memory for one server by the number of instances planned for the system.

______________________
Disk space
The following minimum disk space:
  • 5 MB for the /var directory
  • 30 MB for the /opt directory if you create mount points
  • 3 GB for the /opt/tivoli/tsm directory
  • 2 GB for the /opt directory if you do not create mount points
  • 600 MB for the /tmp directory
  • 300 MB for the /usr directory
  • 2 GB in the home directory
Tip: Expect to use more space for problem determination.

Significant additional disk space is required for database and log files. The size of the database depends on the number of client files to be stored and the method by which the server manages them. The default active log space is 16 GB, the minimum that is needed for most workloads and configurations. Allocate at least three times the active log space for the archive log (48 GB). Ensure that you have sufficient resources if you are using deduplication or expect a heavy client workload.

For optimal performance and to facilitate I/O, specify at least four separate directories or Logical Unit Numbers (LUNs) to be used by the database and logs. By making these specifications, I/O is balanced across multiple directories or mounts.

Ensure that you see the capacity planning section for more details about disk space.

Version 6.3

The HP Itanium system must have operating system 11i v3 (11.31) with the most current maintenance levels installed.
11i v3 with:
  • PHCO_38658 - libc cumulative patch

The latest available service patches for the operating system must be applied. Older levels without patches do not work with the device drivers that Tivoli Storage Manager uses.

The HP maxfiles parameter specifies the number of files a process is allowed to open at any given time. The default value for HP is 60. However, this value is low and can cause server problems. To ensure proper server operation, increase the maxfiles value to at least 512.

Version 6.3

Communication Protocol
A communication method that is installed and activated (shared memory is the default).

Devices and drivers
  • A DVD device that is available for the installation process, if you are installing from DVD media.
  • The Tivoli Storage Manager device driver package does not contain a device driver for this operating system because a SCSI generic device driver is used. Configure the device driver before using the Tivoli Storage Manager server with tape devices.

The Tivoli Storage Manager driver package contains driver tools and ACSLS daemons. You can locate IBM® driver packages at the Fix Central website.

Gunzip utility
The gunzip utility must be available on your system before you install or upgrade the Tivoli Storage Manager Version 6 server. Ensure that the gunzip utility is installed and the path to it is set in the PATH environment variable.

Korn Shell (ksh)
Tivoli Storage Manager server V6.2
Version 6.2
  • A 64-bit Itanium® system.

Recommended and minimum memory requirements and minimum space requirements to run:
Recommended: 12 GB. 16 GB if you are using deduplication.

Also consider:
· Large production servers may require more than the recommended amount of memory.

Minimum: 4 GB for small production servers. A server is considered to be small if it has the following characteristics:

· It does not use storage pool deduplication.

· It supports only a small number of clients, or the nightly backup data transferred is 100 GB or less.

· It is used only as a library manager.

· On a machine having only 4 GB of RAM, only a single server is being run.

Additional information to consider:
· If the intention is to run with less than the recommended amount of memory, it is further suggested that this configuration be tested under those circumstances to determine that this will support the intended workload in this particular environment. Or if V6.1 servers are already implemented in these less then recommended memory environments, that would also provide a proof point that this may be suitable for these particular environments.

Disk Space:

  • 5 MB for the /var directory
  • 10 MB for the /opt directory if you create mount points
  • 2 GB for the /opt/tivoli/tsm directory if you create mount points
  • 2 GB for the /opt directory
  • 600 MB for the /tmp directory
  • 300 MB for the /usr directory
  • 2 GB in the home directory
