Veritas Volume Manager 5.0 Release Notes HP-UX 11i v3 (5992-1952, August 2011)

This message can be ignored. Once the disk group is imported successfully, there should be
no problem in accessing its volumes.
• Problem
Online shrinking of an active swap volume is not supported.
Workaround
The vxassist command has no built-in protection to prevent you from shrinking the swap
volume without first shrinking what the system sees as available swap space. If it is necessary
to shrink the swap volume, the operation must be done in single user mode and the system
must be rebooted immediately. Failing to take these precautions can result in unknown system
behavior.
• Problem
The vxassist command does not add a mirror and a log when processing a command such
as the following:
# vxassist mirror volume layout=log ...
Workaround
The mirror is added, but the log is silently omitted. To add a log and a mirror, add them in
two separate vxassist invocations, as follows:
# vxassist mirror volume ...
# vxassist addlog volume ...
• Problem
Growing or shrinking layered volumes result in failures during resynchronization.
Workaround
Due to the current implementation of a resize of layered volumes, it is recommended that you
do not grow or shrink layered volumes (for example, stripe-mirror or concat-mirror) during
resynchronization. This limitation does not apply to ISP layered volumes.
Internally, VxVM converts the layout of layered volumes and updates the configuration database
before it does the actual resize. This causes any ongoing operation, such as a
resynchronization, to fail.
If the system reboots before the grow or shrink of a layered volume completes, the volume is
left with an intermediate layout. In this case, you have to use vxassist convert to restore
the volume to its original layout.
After a layered volume is resized, the volume, plex, and subdisk names associated with the
subvolumes, are changed.
• Problem
The vxdisksetup command gives the error message “attribute unrecognized” when the
attribute old_layout is used to make a disk into a VxVM controlled disk. The old_layout
attribute is no longer supported.
Workaround
Use the noreserve attribute instead.
• Problem
The vxdiskadm command requires two attempts to replace a failed disk. The first attempt
fails and the following message is displayed:
/usr/lib/vxvm/voladm.d/bin/disk.repl: test: argument expected
Workaround
The command is not completed and the disk is not replaced. If you now re-run the command,
the replacement completes successfully.
