CBR3456I A write protect indication for volume volser was received from drive drive-name.
Explanation
An erase or write request to volume volser mounted on drive drive-name was rejected because the drive indicated the volume may be write protected.
System action
Either the drive or volume could have caused the failure.
If the volume has not failed a previous request on another drive, the drive will be marked not operational and the volume flagged as having failed this request. The volume will then be mounted on another drive and the request retried.
If, however, the volume has failed a previous request on another drive, the previous drive will be marked operational and message CBR3304I will be issued identifying the volume as the cause of failure.
Operator response
If the drive becomes not operational, vary the drive back online. Contact hardware support if the drive continues to become not operational.
If the volume has been identified as the cause of error, see message CBR3304I and follow the instructions listed.
