Solving Shared Storage Problems
Data on shared storage appears
to be overwritten.
The second node cannot
connect to the shared drives.
Problem
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 Fibre Channel
storage hub or FC-AL switch does
not exist.
Shared RA4000/4100 drives are
not assigned the same drive
letters on both nodes.
The second node was powered up
before the Fibre Channel storage
hub, FC-AL switch, or the
RA4000/4100.

Possible Cause Action
1. Ensure that 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 that 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
documentation that came with
your storage system.
2. Verify that all Fibre Channel
cables are properly connected
to their GBIC-SW modules.
Run Windows NTS/E Disk
Administrator or Windows 2000
Advanced Server Disk Management
on each node to verify all shared
drives are assigned identical,
permanent drive letters.
Shut down the second node, power
it down, then power it up.
