Using tape devices and libraries in a WPAR with Tivoli Storage Manager servers and storage agents

Technote (FAQ)


Question

Can I use tape devices and libraries in a detached workload partition (WPAR) with Tivoli Storage Manager servers and storage agents?

Answer

In AIX 7.1, Tivoli Storage Manager servers and storage agents can run in detached WPARs with full tape and library access.
Installation prerequisites

  • AIX 7.1 SP 1 (7100-00-01-1037).
  • The WPAR must be a detached-system WPAR.
  • The FC adapter can be either a dedicated adapter or a virtual NPIV adapter.
  • The FC adapter must be assigned to the WPAR. Do not assign individual tape or library devices to the WPAR.
  • When installing either the Atape or Tivoli Storage Manager device driver, you must install the same driver in both the global corral and the WPAR, even if you are not using any devices in the global corral. Failure to install the same driver makes the devices appear as "Defined" in the WPAR instead of "Available."

Using devices
  • With the Atape driver:
    1. Install the Atape driver in the global corral.
    2. Install the same Atape driver in the WPAR.
    3. Reboot the global system.
  • With the Tivoli Storage Manager device driver:
    1. Install the following Tivoli Storage Manager components in the WPAR:
      • The server or storage agent
      • The Tivoli Storage Manager device driver
      • Optional: The messages
    2. Install only the Tivoli Storage Manager device driver into the global corral.
    3. Reboot the global system.

Important: When a WPAR starts, the Tivoli Storage Manager devices appear as "Defined" instead of as "Available." This is a restriction of AIX and the Tivoli Storage Manager device driver. To make the Tivoli Storage Manager devices appear as "Available," you must run the cfgwpardd script before starting the Tivoli Storage Manager server:
