5. If you find disk space errors, there may not be enough physical disk space for the
expansion. Add more physical storage or change the size of expansion. Then retry.
6. If no disk space problems were found, or if correcting them does not solve the
problem, make sure that the physical storage partition is valid. Correct any
problems, and retry.
7. If the partition is valid or if correcting it does not solve the problem, look for I/O
errors.
8. If I/O errors are found, consult technical support.
9. Otherwise, look for an RPC timeout during execution of the expand command.
See if the server is busy by running the top or ps –x command on the VTL
server.
10. If the server seems excessively busy, stop any unnecessary processes, and retry
the expansion operation.
11. If the problem persists or if the event logs show no obviously relevant errors,
contact technical support.
Issue: Client cannot see tape library/drives provisioned by VTL
Indications: A client operating system or application does not correctly detect virtual devices.
Diagnostics: Further characterize the problem, and determine the cause.
Case: Neither the operating system nor applications appear to see the device
1. See if the operating system includes the device in its configuration.
