Table 15 Troubleshooting for XP Thin Provisioning (continued)
Causes and Solutions Problems
Causes:
See “Troubleshooting when using XP RAID Manager” (page 84)
to identify the cause.
Solutions:
•
After selecting the Refresh or Refresh All command from the
File menu at the top left of the Remote Web Console window,
make sure that the processing for increasing V-VOL capacity
meets conditions described in
“Increasing V-VOL Capacity”
(page 67) .
•
Retry the operation in 10 minutes.
• Ask HP technical support to solve the problem.
V-VOL capacity cannot be increased.
Cause:
•
Zero data in the V-VOL cannot be discarded from Remote
Web Console because the V-VOL does not meet the conditions
described in
“Releasing Pages in a V-VOL” (page 71) .
Solution:
•
Make sure that the V-VOL meets the conditions described in
“Releasing Pages in a V-VOL” (page 71) .
Cannot discard zero data in a V-VOL.
Cause:
• Pages of the V-VOL are not released because the process of
discarding zero data was interrupted. For details, see
“Releasing Pages in a V-VOL” (page 71) .
Solution:
•
Make sure that the V-VOL meets the conditions described in
Releasing Pages in a V-VOL and perform the solution.
The V-VOL cannot not be released though
zero data in the V-VOL is discarded.
Cause:
•
The pool is full.
• The pool-VOL is blocked.
•
The pool-VOL of the external volume is blocked.
Solutions:
•
Add pool-VOLs to the pool to increase the free space in the
pool. For more information, see
“ Creating a Pool” (page 58) .
• To restore the pool-VOL, contact the Hitachi Data Systems
Technical Support Center.
•
If the pool-VOL is an external volume, check the condition of
the external storage system, for instance the path blockade.
• After performing the above-mentioned solutions, release the
Protection attribute of the V-VOLs using the Data Retention
window of Remote Web Console (if the Data Retention Utility
is installed).
For information about operating procedures, see the HP
StorageWorks XP24000/XP20000 Data Retention Utility User
Guide.
Cannot release the Protection attribute of
the V-VOLs.
