# vxassist [-g diskgroup] [-f] growto volume length \

[attributes...]

You can use storage specification attributes with this command to restrict the

storage that is used to grow a volume.

For example, the following command expands the volume vol1 to 10 GB, but

excludes storage on controller c1 from being allocated:

# vxassist -g mydg growto vol1 10g \

use_storage=’noneof("Controller"="c1")’

This operation fails if the new length specified is smaller that the current size of

the volume.

Increasing the size of a volume by a specified amount

The following command grows a volume by a specified amount:

# vxassist [-g diskgroup] [-f] growby volume length \

[attributes...]

For example, the following command grows the volume vol1 by 1 GB by allocating

contiguous storage:

# vxassist -g mydg growby vol1 1g layout=contig

The setting layout=contig allows only contiguous regions of disk to be used for

plexes or columns. By default, the length of a volume is increased by first extending

existing subdisks in the volume if possible, and then by adding and associating

new subdisks. This default behavior corresponds to the attribute setting

layout=nocontig.

Reducing the size of a volume to a specified length

The following command reduces the length of a volume:

# vxassist [-g diskgroup] [-f] shrinkto volume length \

[attributes...]

For example, the following command shrinks the volume vol1 to 5 GB:

# vxassist -g mydg shrinkto vol1 5g

This operation fails if the new length specified is larger that the current size of

the volume.
