Specifying Empty Pool Action

When all tapes in a resource pool are used and additional tapes are required to complete a backup or MPC job, CA VM:Backup must take some action to complete the job. Set the action CA VM:Backup is to take on the Modify Resource Pool poolname screen.

Empty Pool Action for Superpools

If a backup or MPC job references a superpool, when a particular DASDtape resource pool in the superpool runs out of available tapes, CA VM:Backup ignores the specified empty pool action for that resource pool and uses a tape from the next resource pool in the superpool pool list. When CA VM:Backup has used the last volser in the last resource pool in the list, CA VM:Backup takes the empty pool action for that resource pool. Set the action CA VM:Backup is to take for each DASDtape resource pool in the superpool on the Modify Resource Pool poolname screen.

A resource pool can run out of available tapes during a backup job. To specify the action that CA VM:Backup is to perform, select one of the following options on the Modify Resource Pool poolname screen:

Hold the job

CA VM:Backup places the job on hold.

Ask for a volser

CA VM:Backup prompts the tape operator to enter the volser of a tape to use to complete the job. CA VM:Backup does not add the volser is to the resource pool.

Do not use this option for DASDtape resource pools.

Use this option only if it is necessary.

Ask, adding to the pool

(Default) CA VM:Backup prompts the tape operator to enter the volser of a tape to use to complete the job. When the backup or MPC job completes, CA VM:Backup adds the volser to the resource pool. If the job references a superpool, CA VM:Backup adds the volser to the last DASDtape resource pool that is defined to the superpool.

CA VM:Backup adds the volsers of all tapes that are obtained from the tape operator under the control of this option to the resource pool. This addition is performed whether CA VM:Backup used the tape during the backup or the MPC job, or not. This situation can arise if an error in backing up a minidisk causes the tape to rewind.

If your data center uses CA VM:Tape, CA VM:Backup ignores these options for all resource pools other than DASDtape resource pools. When a CA VM:Tape resource pool runs out of tapes, more tapes must be added through CA VM:Tape facilities.
