VXPLEX – Examples
Make a copy of a Volume
Sample volume used for this demo:
TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 pl appsvol-01 - DISABLED 204800 - - - - pl oravol-01 oravol ENABLED 204800 - ACTIVE - - # vxplex -g oradg cp oravol appsvol-01
[box type=”info” align=”alignleft” ] Once you made a copy of volume, you can associate and use it as separate volume. [/box]
Replace the old plex with newplex
TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 pl appsvol-01 - DISABLED 204800 - - - - pl oravol-01 oravol ENABLED 204800 - ACTIVE - - # vxplex -g oradg mv oravol-01 appsvol-01 TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 pl appsvol-01 oravol ENABLED 204800 - ACTIVE - - pl oravol-01 - DISABLED 204800 - - - -
Attach each named plex to the named volume
TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 pl appsvol-01 oravol ENABLED 204800 - ACTIVE - - pl oravol-01 - DISABLED 204800 - - - - # vxplex -g oradg att oravol oravol-01 TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 pl appsvol-01 oravol ENABLED 204800 - ACTIVE - - pl oravol-01 oravol ENABLED 204800 - ACTIVE - -
Detach each of the named plexes
TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 pl appsvol-01 oravol ENABLED 204800 - ACTIVE - - pl oravol-01 oravol ENABLED 204800 - ACTIVE - - # vxplex -g oradg -v oravol det oravol-01 TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 pl appsvol-01 oravol ENABLED 204800 - ACTIVE - - pl oravol-01 oravol DETACHED 204800 - STALE - -
Disassociate each of the named plexes
TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0
pl appsvol-01 appsvol DISABLED 204800 - EMPTY - -
# vxplex -g oradg dis appsvol-01
TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0
pl appsvol-01 - DISABLED 204800 - - - -
Disassociate and remove the plexes and subdisks from the configuration
# vxplex -g oradg -o rm dis appsvol-01

Convert a snapshot plex into a regular plex, or vice versa
# vxplex convert state=SNAPDONE|ACTIVE testvol-01
Cancel the effects of a snapstart
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 pl testvol-01 oravol ENABLED SNAPDIS 204800 CONCAT - WO sd oradisk02-01 testvol-01 oradisk02 0 204800 0 c3t2d0 ENA # vxplex snapabort plex 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
– This command also removes the plex & Sub Disk from configuration.
Attach the SNAPSHOT back to the volume
