As in previous versions, if the volume is striped, you should firstly relayout the volume to add one column to your stripe.

vxassist relayout <vol> ncol=...  <you_new_lun>

Then grow the volume :

vxassist growby <vol> ...

Then grow the filesystem :

Hi Experts,

A question regarding to resize the UFS filesystem through vxvm volume,
here's the situation:

There are three vxvm striped volumes created within same diskgroup which
accross on 5 individual LUNs,and one of volume capacity is used up and need
expand,can we do that as:

- add one or more(less then 5) physical LUN with same size as above LUNs to OS
- join new assigned LUNs into above vxvm diskgroup
- resize the volume to be expanded online by "vxresize" command
- growup ufs filesystem online

In earlier vxvm such as 3.x,above attempt may fail as the target volume is
accrossing on 5 physical LUNs and must add new disks by the same amount
(means at least 5 new LUNs need adding) if resize the volume online.

I wonder if the latest vxvm 5.x can support it ?
