An attempt was made to create a temporary volume to hold the restored data, which required that a new volume be created in the same caching I/O group as the target volume for the restore operation. The new volume was not created because no free volume IDs or volume copy IDs were available in the system.
Determine whether the system includes unwanted volumes or volume copies. If so, remove unwanted volumes or volume copies by using the rmvolume or rmvolumecopy command, and then retry the command.
