DEVICE LIMIT EXCEEDED

Reason:

This message appears during CA VM:Tape initialization for one of the following reasons:

The DEVICE records in the VMTAPE CONFIG file contain too many devices to be managed by the CMS I/O handler.
No virtual addresses in the range 310-7FF are available for CA VM:Tape to use. CA VM:Tape uses these addresses to attach tape drives to itself before attaching the drives to the requesting users.

After this message, CA VM:Tape generates message 004T and returns control to CMS.

Action:

Detach any virtual devices in the CA VM:Tape service virtual machine in the range 310-7FF and try to restart CA VM:Tape. If initialization fails again, the VMTAPE CONFIG file specifies more devices than the CMS I/O interrupt handler can service. Ask the CA VM:Tape system administrator to modify or delete DEVICE records in the VMTAPE CONFIG file until enough devices are removed to allow CA VM:Tape to initialize.
