Operation: Memory Addition
Status: PENDING
The following are the valid values for the Status: field of the vparstatus output:
Table 6-2 Values for the Status field
DefinitionState
The requested operation is pending. When this is the Status value, you can cancel the operation.Pending
The requested operation has completed successfully.Pass
The requested operation has encountered an early failure before it started on the target operating
system. It will not have a valid SequenceID.
Fail
The requested operation has been aborted by the Operating System on the virtual partition, or by
the user explicitly canceling the operation. Refer to the vPars Monitor event log for the cause of
the failure.
Abort
When the status indicates Fail or Abort, or remains Pending for a long time, you can do the
following to get more information on the status:
• Dump the vPars Monitor log using vparextract -l and examine the output.
• Run evmget | evmshow on the target virtual partition and examine the output pertaining
to the SequenceID.
• Check the /var/adm/syslog/syslog.log file on the target virtual partition.
Online float memory addition or deletion can take significant time or even fail if the target virtual
partition is under memory pressure. Use vmstat or other virtual memory monitoring tools to
check the memory pressure on the target partition. In particular, if you are deleting float memory,
make sure the target virtual partitions is not under memory pressure.
Cancel Pending Usage
To use the cancel pending feature:
1. Determine which vPar has the pending operation, and acquire the sequenceID.
• If necessary, use vparstatus to determine which vPar has the pending operation. For
example:
keira1# vparstatus
...

keira2 1/ 128 4352p 1/ 128 640p
keira3 0/ 0 1224 0/ 0 0
The vparstatus output shows that a pending online addition of memory is occurring
on keira2.
• Use the vparstatus -v option to acquire the sequenceID. For example:
keira1# vparstatus -p keira2 -v
