  SCSI disk errors, mount verification? 
 The Question is:
 
Machine:
DEC Alpha aServer 4100 5/600 8MB
Operating System:
 OpenVMS V6.2-1H3
 
We have problem with  disk.
On one SCSI controller are
  OpenVms say:
1. DKC0:   DEC RZ1CB-CS
2. DKC100: DEC RZ1CB-CS
3. DKC200: DEC RZ1CB-CA
4. DKC300: DEC RZ1CB-CA
5. DKC400: COMPAQ BD018635
6. DKC500: COMPAQ BD018635
7. MKC600: TZ89
 
 Outside label say:
1. DS-RZ1CB-VW
2. DS-RZ1CB-VW
3. DS-RZ1CB-VW
4. DS-RZ1CB-VW
5. DS-RZ1ED-VW
6. DS-RZ1ED-VW
 
With COMPAQ BD018635 ( or? DS-RZ1ED-VW )
we have "MountVerify mounted" problem.
After the disk was thaken out/in from
slot,disk is mounted ok,but error count
for disk is bigger.*this error repeat's
( other DEC RZ1CB-CS, DEC RZ1CB-CA  disk
dont have this problem )
 
Is there any Openvms patch for this
 
DS-RZ1ED-VW is supported
option said Compaq in
AlphaServer 4100 Supported Options List
but
how it is with
 COMPAQ BD018635
 
Can You help me please
 
 The Answer is :
 
  You appear to have a hardware or a SCSI configuration problem.
 
  OpenVMS does not generally support hot-swapping SCSI disks,
  though there are controllers and configurations which can
  quiesce the bus and allow for the on-line replacement of
  failing storage.  Please check the documentation for the
  particular storage controller and storage hardware
  configuration for details and supported features.
 
  You will want to contact your hardware service organization
  to verify the configuration and the firmware versions, and
  you will want to ensure that the current mandatory ECO kits
  for OpenVMS have been installed.  You will also want to look
  at the contents of the system error log, to determine what --
  if anything relevent -- is being logged.  You wil further want
  to verify SCSI unit number settings for the SCSI controller(s)
  and for all SCSI devices, as well as correct SCSI termination.
