When the system requests a shelf-resident volume, the following message is displayed requesting you to mount an optical disk cartridge on an operator-accessible optical drive:
CBR4400A Mount volume volser on drive drive-name. Shelf location is shelfloc.
If the volser is ??????, the request is for an unlabeled optical volume. Locate an unlabeled optical disk cartridge and load it on drive drive-name.
If a volume serial number is specified in volser, the request is for an already labeled optical volume. Locate the optical disk cartridge and load it into the drive drive-name. The system issues the following message:
CBR4401I Volume volser mounted on drive drive-name.
To label a disk on an operator-accessible drive, see Labeling an optical disk on a 3995 operator-accessible drive.
