Solving Shared Storage Problems
Problem
Data on shared storage appears
to be overwritten.
The second node cannot
connect to the shared drives.
Troubleshooting the Compaq ProLiant Clusters HA/F100 and HA/F200 6-9
continued
Possible Cause
MSCS may not be loaded and
therefore cannot manage access
to drive volumes in the shared
storage.
Physical connection from the
second node to the Compaq
StorageWorks Fibre Channel
Storage Hub does not exist.
Shared RA4000 drives are not
assigned the same drive letters on
both nodes.
The second node was powered on
before the storage hub or the
RA4000.
Action
1. Ensure MSCS is loaded on
both cluster nodes.
2. Using the Control Panel
Service applet on each node,
verify the cluster service is
running.
1. Verify all Fibre Channel cables
are properly connected to the
GBIC-SW modules. For details
on how to connect the
GBIC-SW modules and the
Fibre cables, see the Compaq
RA4000 Storage System User
Guide .
2. Verify that all Fibre Channel
cables are properly connected
to their GBIC-SW modules.
Run Windows NT Disk Administrator
on each node to verify all shared
drives are assigned identical,
permanent drive letters.
Shut down the second node, turn it
off, then turn it on.
