Jason..i think DKA0 has hardware problem

Hello Wong/Jason

Some background please!
Has the DS15 been working for a time and now suddenly started with problems?
Has it been opened lately and the configuration changed? etc...

Step by step ... you've got good suggestions above...

If VMS is running then skip this bit, go down and do the suggested VMS commands...

Imagine we've just switched on, you should see
>>>
>>> boot
VMS should start, you'll see lots of messages for a few minutes.
When they stop hit
USername: SYSTEM
Password:
$
$
$ sho error (what do you get?)
---
Now read what Volke suggested at 06:13 on the 20th. ie his $ANALY/DISK commands ...

do they (eventually: 5-60 seconds estimate) finish with or without ERRORS.

Both commands will probably tell you the QUOTA.SYS file is missing. ignore this.

TEll us what you see!

Regards
Steven

Jason,

the commands I've suggested should be a step-by-step approach to narrow down on the MOUNTVER problem.

The commands start by generating an increasing IO load on DKA0 to see, if the disk will log errors under load. BACKUP to the NLA0: (NULL) device will 'write' the saveset data to the 'bit-bucket', this command just runs the BACKUP IO load against DKA0:. If all those commands succeed and don't generate errors, then try the ultimate test by writing a backup to tape. If this would cause MOUNTVER, the problem is with the tape or the SCSI bus.

Volker.
