Setting the library mode

Edit online

For the IBM Storage Protect server to access a SCSI library, the tape device must be set for the appropriate mode.

About this task

Some libraries have front panel menus and displays that can be used for explicit operator requests. However, if you set the tape device to respond to such requests, the device typically does not respond to IBM Storage Protect requests.

Some libraries can be placed in SEQUENTIAL mode, in which volumes are automatically mounted in drives by using a sequential approach. This mode conflicts with how IBM Storage Protect accesses the tape device. A library that is configured in SEQUENTIAL mode is not detected by the system device driver as a library changer device, IBM® tape device driver, and IBM Storage Protect tape device driver.

Procedure

  1. Refer to the documentation for your tape device to determine how to set the library mode.
  2. Set the mode to the appropriate mode for your tape device. For most tape devices, the appropriate mode is called the RANDOM mode. If your tape device does not have a RANDOM mode, consult the documentation for your device to identify the appropriate mode.
