211Examples of using ISP

Resizing a volume

Note: The following examples show how to resize volumes that do not contain

file systems (volume type gen). If an application is using the volume to store

data, use the appropriate utility to reduce the size of the data object before

reducing the size of the volume, or to increase the size of the data object after

increasing the size of the volume.

For volumes that contain file systems (volume type fsgen), use the

vxresize

command to change both the size of the file system and the volume.

Grow a volume by 5 gigabytes:

# vxassist -g exdg growby vol1 5g

Grow an existing 10-gigabyte volume to 15 gigabytes without using disks from

the enclosure e1:

# vxassist -g exdg growto vol1 15g \

use_storage='noneof("Enclosure"="e1")'

Shrink a volume by 10%:

# vxassist -g exdg growby vol1 10%

Shrink an existing 15-gigabyte volume to 10 gigabytes:

# vxassist -g exdg shrinkto vol1 10g

Adding or removing mirrors

Add a mirror to an existing volume:

# vxassist -g exdg mirror vol1

Add two mirrors to a volume:

# vxassist -g exdg mirror vol1 nmirror=2

Add a mirror to the volume vol1, where the new mirror is like the existing plex

p1:

# vxassist -g exdg mirror vol1 plexname=p1

Remove a mirror from a volume:

# vxassist -g exdg remove mirror vol1

Remove the plex p1 from the volume v1:

# vxassist -g exdg remove mirror vol1 plexnames=p1
