VXVOL – Examples:
Note: Examples just shows how to use the command with specific options. You need to decide how to use and when to use.
Enable locally disabled volume (DISABLED State)
# vxvol -g oradg -U fsgen enable oravol
Initialize Volume for a Use:
This applies where volume has been created by vxmake command and volume yet to initialize. You may also need to use where the volume has been set to uninitialized by vxmend.
Sample volume:
v oravol02 - DISABLED EMPTY 0 ROUND - gen pl oravol02-01 oravol02 DISABLED EMPTY 204800 CONCAT - RW sd oradisk02-01 oravol02-01 oradisk02 0 204800 0 c3t2d0 ENA
Sets the state for the specified plex to CLEAN, and sets all other plexes to STALE for that volume
# vxvol -g oradg init clean oravol02 v oravol02 - DISABLED CLEAN 0 ROUND - gen pl oravol02-01 oravol02 DISABLED CLEAN 204800 CONCAT - RW sd oradisk02-01 oravol02-01 oradisk02 0 204800 0 c3t2d0 ENA
Writes zero blocks to all plexes in the volume, up to the length of the volume
# vxvol -g oradg init zero oravol02 v oravol02 - ENABLED ACTIVE 0 ROUND - gen pl oravol02-01 oravol02 ENABLED ACTIVE 204800 CONCAT - RW sd oradisk02-01 oravol02-01 oradisk02 0 204800 0 c3t2d0 ENA
Enables the volume and its plexes but leaves the volume uninitialized
# vxvol -g oradg init enable oravol02 v oravol02 - ENABLED EMPTY 0 ROUND - gen pl oravol02-01 oravol02 ENABLED EMPTY 204800 CONCAT - RW sd oradisk02-01 oravol02-01 oradisk02 0 204800 0 c3t2d0 ENA
Sets the state for all plexes associated with volume to ACTIVE
# vxvol -g oradg init active oravol02 v oravol02 - ENABLED ACTIVE 0 ROUND - gen pl oravol02-01 oravol02 ENABLED ACTIVE 204800 CONCAT - RW sd oradisk02-01 oravol02-01 oradisk02 0 204800 0 c3t2d0 ENA
Put volume into maintenance mode
# vxvol -g oradg maint oravol VxVM vxvol ERROR V-5-1-1222 Volume oravol is enabled, use -o force
To make the volume force maintenance
# vxvol -g oradg -o force maint oravol v oravol - DETACHED ACTIVE 204800 SELECT - fsgen pl oravol-01 oravol ENABLED ACTIVE 204800 CONCAT - RW sd oradisk01-01 oravol-01 oradisk01 0 204800 0 c3t1d0 ENA
Set the read policy for a volume
# vxvol -g oradg rdpol round oravol v oravol - ENABLED ACTIVE 204800 ROUND - fsgen pl oravol-01 oravol ENABLED ACTIVE 204800 CONCAT - RW sd oradisk01-01 oravol-01 oradisk01 0 204800 0 c3t1d0 ENA pl oravol-02 oravol ENABLED ACTIVE 204800 CONCAT - RW sd oradisk02-01 oravol-02 oradisk02 0 204800 0 c3t2d0 ENA
Perform synchronization operation
# vxvol -g oradg -o bg resync oravol
Re-sizing the volumes
Sample volume:
v oravol - ENABLED ACTIVE 204800 SELECT - fsgen pl oravol-01 oravol ENABLED ACTIVE 204800 CONCAT - RW sd oradisk01-01 oravol-01 oradisk01 0 204800 0 c3t1d0 ENA
After Re-sizing the volume:
# vxvol -g oradg -o bg set len=value oravol
v oravol - ENABLED ACTIVE 102400 SELECT - fsgen
pl oravol-01 oravol ENABLED ACTIVE 204800 CONCAT - RW
sd oradisk01-01 oravol-01 oradisk01 0 204800 0 c3t1d0 ENA
[box type=”warning” align=”alignleft” ]To resize the volume, always use vxresize. If you set the incorrect length using vxvol , then volume may not be startable. [/box]
Enable fastresync on Volume
# vxvol -g oradg set fastresync=on oravol
Start the specified Volume
# vxvol -g oradg -o bg start oravol
start the specified volume forcefully
# vxvol -g oradg -f start oravol
Stop the specified Volume
# vxvol -g oradg -o force stop oravol v oravol - DISABLED CLEAN 204800 SELECT - fsgen pl oravol-01 oravol DISABLED CLEAN 204800 CONCAT - RW sd oradisk01-01 oravol-01 oradisk01 0 204800 0 c3t1d0 ENA
Start all Volumes in the disk group
# vxvol -g oradg -o bg,delayreover,slow startall
Stop all Volumes in the disk group
# vxvol -g oradg -o force -o bg stopall
