Patches and Fixes in This Version
Chapter 1 31
# vxassist relayout vol layout=stripe ncol=2
The volume vol is converted to a 2-column volume, but it is still
mirrored even if the layout attribute is specified as stripe and
nomirror.
• Workaround: None.
vxassist Command Does not Add a Mirror and a Log
• 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 ...
The mirror is added, but the log is silently omitted.
• Workaround: If a log and a mirror are to be added, add the mirror
and the log in two separate vxassist invocations, as follows:
# vxassist mirror volume ...
# vxassist addlog volume ...
Crash Recovery Following Snapback Operations There are two
scenarios that demand action when the system crashes during a
snapback operation. The two scenarios involve the use of the vxassist
command with resyncfromoriginal and resyncfromreplica options.
Crash Recovery after using vxassist -o resyncfromoriginal snapback
snapvol
• Problem: When you use the following command:
# vxassist -o resyncfromoriginal snapback snapvol
to execute a default snapback operation (resynchronizing from the original
volume), and the system crashes while the operation is still in progress, you
will find, when the system comes back up and the volumes are restarted,
that the snapshot plexes are not associated with any volume.
• Workaround: To recover from this situation, you should use the following
procedure:
Step 1. Use the following commands to discover the original volume name of
each snapshot plex:
# volrid=‘vxprint -g diskgroup -p -F “%snap_rid” plexname‘
# vxprint -g diskgroup -n -v -e v_rid=$volrid
