Unlocking a System’s Lock

If you cannot restart CA VM:Tape (because of a power failure or hard machine check, for example), use the SDC UNLOCK command to clear the existing lock.

For example, to recover from a lockout condition on system VMTAPE1, reset the lock on its VMTB10 minidisk by entering:

vmtape sdc unlock vmt1b0 vmtape1

CA VM:Tape responds as follows:

WRITING LOCK CLEARED ON VMT1B0 FOR VMTAPE1
