HP-UX: System requirements for HP-UX systems

To install Tivoli® Storage Manager server on an HP-UX system, it is necessary to have a minimum level of hardware and software, including a communication method and the most current device driver.

Hardware requirements

These tables list the minimum hardware and software requirements for the installation of a Tivoli Storage Manager server. Use these requirements as a starting point. You can find the most current information about system requirements at Tivoli Storage Manager Supported Operating Systems.

See IBM Tivoli Storage Manager Optimizing Performance (V7.1.1) for server configuration guidelines and best practices.

Table 1 describes the minimum hardware requirements that are needed for your Tivoli Storage Manager HP-UX system. The installation fails if you do not have the minimum requirements. For more details about planning disk space, see HP-UX: Capacity planning.

Type of hardware Hardware requirements
Hardware

A 64-bit Intel Itanium system.
Disk space The following minimum values for disk space:
  • The /var directory space requirements for new installations and version upgrades:
    • 512 MB for new installations
    • 2560 MB for version upgrades
  • 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
  • 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. When you create the active log, you need at least 64 GB in size to run replication. If replication and data deduplication are both being used, create an active log of 128 GB in size. Allocate at least three times the default 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 IBM Tivoli Storage Manager Optimizing Performance (V7.1.1) 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.
  • If you plan to use node replication without data deduplication, the system requires 32 GB of memory. Node replication with data deduplication requires a minimum of 64 GB of memory.
Devices

A DVD device that is available for the installation process, if you are installing from DVD media.

Software requirements

Table 2 describes the minimum software requirements that are needed for your Tivoli Storage Manager HP-UX system.

Table 2. Software requirements
Type of software Minimum software requirements
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.
