# vxvoladm -g exdg evacuate subdisk vol1 sd=sd01
Evacuate subdisks sd11 and sd12 from volume vol1:
# vxvoladm -g exdg evacuate subdisk vol1 sd=sd11,sd12
Evacuate disks disk01 and disk01 from volume vol1:
# vxvoladm -g exdg evacuate disk vol1 \!disk01 \!disk02
Evacuate columns 4 and 7 of volume vol1:
# vxvoladm -g exdg evacuate column vol1 columnnames=4,7
Evacuate mirror p1 of volume vol1:
# vxvoladm -g exdg evacuate mirror vol1 plexnames=p1
Evacuate columns 3 and 4 of mirror p1 from volume vol1:
# vxvoladm -g exdg evacuate column vol1 columnnames=3,4 \
plexnames=p1
Using Clone Pools to Implement Off-Host Processing
In this scenario, snapshots are taken of a set of five volumes, vol1 through vol5, in the data
storage pool within the hrdg disk group. These snapshots are then made available to a different
host so that a backup can be made of the data.
1. First create a clone pool, snappool1, to hold the snapshots:
# vxpool -g hrdg create snappool1
Note As snappool1 is the second storage pool to be added to the disk group after the data
pool, it is automatically created as a clone pool.
The disk group can be split and clone pool taken to a new disk group. This new disk group
should be deported from this host and imported on the host where the data from the volumes
could be backed up.
2. Create five concat volumes in the clone pool to act as snapshots for the volumes in the data
pool:
# vxvoladm -g hrdg -p snappool1 make snapvol1 10g
# vxvoladm -g hrdg -p snappool1 make snapvol2 1g
# vxvoladm -g hrdg -p snappool1 make snapvol3 50g
# vxvoladm -g hrdg -p snappool1 make snapvol4 25g
# vxvoladm -g hrdg -p snappool1 make snapvol5 20g
