VERITAS Volume Manager 4.1 Release Notes
Known Problems and Workarounds
Chapter 120
vxplex -o rm dis plex name
For example, to remove the rootvol plex associated with rootdisk02:
# vxprint -g rootdg rootvol
TY NAME ASSOC KSTATE LENGTH PLOFFS STATE
v rootvol root ENABLED 524288 - ACTIVE
pl rootvol-01 rootvol ENABLED 524288 - ACTIVE
sd rootdisk01-03 rootvol-01 ENABLED 524288 0 -
pl rootvol-02 rootvol ENABLED 524288 - ACTIVE
sd rootdisk02-03 rootvol-02 ENABLED 524288 0 -
# vxplex -o rm dis rootvol-02
NOTE The TUTIL0 and PUTIL0 fields have been removed in the above vxprint
output for readability.
• Once the system has been repaired and is up in normal mode, the root volume can be
mirrored using the command:
# vxassist -g rootdg mirror rootvol dm:rootdisk02
Utility Issues
Warning Message at Boot Time
A message such as the following is displayed if an attempt is made to open a volume at boot
time before any disk group has been imported.
WARNING: VxVM vxio V-5-0-23 Open on an spurious volume device (hex_id) encountered. This
device may be valid, but has not yet been configured in the kernel.
This message may be ignored. Once the disk group has been imported successfully, there
should be no problem in accessing its volumes.
Shrinking a Swap Volume
vxassist 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 or lock-up.
