Causes and SolutionsProblems
Causes:
• Zero pages in the THP V-VOL cannot be reclaimed from Remote Web
Console because the THP V-VOL does not meet conditions for
releasing pages in a THP V-VOL.
Solutions:
• Make sure that the THP V-VOL meets the conditions described in
“Releasing pages in a THP V-VOL” (page 131).
Cannot reclaim zero pages in a THP V-VOL.
Causes:
• Pages of the THP V-VOL are not released because the process of
reclaiming zero pages was interrupted.
Solutions:
• Make sure that the THP V-VOL meets the conditions described in
“Releasing pages in a THP V-VOL” (page 131).
The THP V-VOL cannot be released if the
process to reclaim zero pages in the THP
V-VOL is interrupted.
Causes:
• Pool usage level exceeds the threshold.
Solutions:
SIM code such as 620XXX, 622XXX, 625000
or 626XXX was issued.
• Add pool-VOLs to the pool to increase the free space in the pool.
See “Increasing pool capacity” (page 123).
• Perform the operation to reclaim zero pages in order to release pages
in which zero data are stored. See “About releasing pages in a THP
V-VOL” (page 130).
Causes:Formatted pool capacity displayed in the
View Pool Management Status window does
not increase.
• Another pool is being formatted.
• The pool usage level reaches up to the threshold.
• The pool is blocked.
• I/O loads to the storage system are high.
• The cache memory is blocked.
• Pool-VOLs are blocked.
• Pool-VOLs which are external volumes are blocked.
Solutions:
• Confirm the display again after waiting for a while.
• Add pool-VOLs to the pool to increase the free space in the pool.
For more information, see “Increasing pool capacity” (page 123).
• Perform the operation to reclaim zero pages in order to release pages
in which zero data are stored. See “About releasing pages in a THP
V-VOL” (page 130).
• Restore the pool.
• Confirm the display again after decreasing I/O loads of the storage
system.
• Contact HP Technical Support to restore the cache memory.
• Contact HP Technical Support to restore the pool-VOL.
• If the blocked pool-VOL is an external volume, confirm following:
◦ Path blockage
◦ Status of the storage system
If you are unable to solve a problem using the above suggestions, or if you encounter a problem
not listed, please contact HP Technical Support.
