[mod.computers.vax] Write lock on system disk

ramsey%lllasd.DECNET@lll-crg.arpa.UUCP (01/28/87)

There is something very strange going on with one of our MicroVax II's and its
system disk.  I was wondering if anyone else has had this same problem and can
tell me what is going on, or a fix ....  

We have a MicroVAX II with a RA81 system disk.  Twice in the past 3 months, the 
system disk has become WRITE LOCKED, and NO ONE can access it, or the macine.
All terminal access is dead, even the system/operator terminal.  The write lock
light comes on and there is NO WAY of clearing it.  EXCEPT .. to hit the BREAK 
KEY, Power down and back up the system disk and reboot.  

Each time, there is never any errors for the device (using show error). Just
before or during the system/operator terminal spurts..

	%SYSTEM-I-MOUNTVER, _DUA4: has been write locked.  
	Mount verification in progress.

The machine is not used that much, yet.. But I hate to have this happen when it
is .... 

Please keep your responses as simple as possible... I'm a novice at this..

Thanks ahead of time for all your advice and suggestions
