The server has detected a write-protect condition for the given volume.
The server will dismount the volume and continue processing with another volume.
Adjust the write-protect switch on the volume so that writing is allowed. If the write-protect switch on the volume allows writing, verify that the device special file for the drive has proper read and write permissions, at the operating system layer, for the user who is starting the dsmserv process. If the volume is an optical volume and the write-protect switch is already set to allow writing, use the MOVE DATA command to move the data off of the volume. Rewritable volumes may be reformatted and reused after the data is moved to another volume.
