Increases the volume size to a specified length.growto
Increases the volume size by a specified amount.growby
Reduces the volume size to a specified length.shrinkto
Reduces the volume size by a specified amount.shrinkby
Extending to a given length
To extend a volume to a specific length, use the following command:
# vxassist [-b] [-g diskgroup] growto volume length
If you specify the -b option, growing the volume is a background task.
For example, to extend volcat to 2000 sectors, use the following command:
# vxassist -g mydg growto volcat 2000
If you want the subdisks to be grown using contiguous disk space, and you
previously performed a relayout on the volume, also specify the attribute
layout=nodiskalign to the growto command.
Extending by a given length
To extend a volume by a specific length, use the following command:
# vxassist [-b] [-g diskgroup] growby volume length
If you specify -b option, growing the volume is a background task.
For example, to extend volcat by 100 sectors, use the following command:
# vxassist -g mydg growby volcat 100
If you want the subdisks to be grown using contiguous disk space, and you
previously performed a relayout on the volume, also specify the attribute
layout=nodiskalign to the growby command .
Shrinking to a given length
To shrink a volume to a specific length, use the following command:
# vxassist [-g diskgroup] shrinkto volume length
For example, to shrink volcat to 1300 sectors, use the following command:
# vxassist -g mydg shrinkto volcat 1300
