    Your volume is an 8-way stripe (STRIPE 8/512) so you will need 8 LUNs to increase the size of the volume.

    If you don't have 8 LUNs, then you will need to with do a "vxassist relayout" which just needs a relatively small tmp space to relayout, but takes a while to relayout and effects peformance of volume or you can mirror to a new LUN as concat and then remove old mirror, but this requires you temporarlly assign double the storage, but has less impact on performance - see https://www-secure.symantec.com/connect/forums/how-expand-dg-vgbackup-and-after-filesystem-prod01p

Hello,

What is the structure of the volume ? can you paste the output of vxprint ?

It is quite possible that striped volume is getting spread across multiple disks & the available space is all available from one or multiple disk however not enough to equally cut the stripes to grow the volume ..

so if the volume has 3 stripes, you should have spaces available in 3 different disks in order for resize to succeed ...

Alternatively, you can try below technote
