Hello.

I need your help .

I wonder if  relayout command will be available for work.
( Stripe layout, ncol=14 to stripe layout, ncol=7  )

I will use the following command.: ( volume relayout ncol 14 -> ncol 7 )

# vxassist -g ccrmapvg01 relayout lvol01 layout=stripe ncol=7 

Is it possible?

If you need anything let me know.

This should work fine, and I see you have plenty of free space in the diskgroup which the relayout requires.

Note there will be a degrade in performance during the relayout so you should run at a quiet period.  If you don't have any quiet periods, then you could add 7 more disks so you have 14 disks free and then mirror to these disks specifying the layout of the mirror of stripe, ncol=7.  This will still impact performance, but I think it will be less and will be quicker (as it doesn't need to copy to a tmp area).
