What storage system is it? Will you need to remove all vpaths/disks afterwards?

The following is an example for the 2105/2107 storage system, to remove all vpaths

rmdev -dl dpo -R (will remove all vpaths)

to remove disks:

lsdev -C -t 2105* -F name (will list the disks, if you are on 2107 change the 2105 part)

lsdev -C -t 2105* -F name | xargs -n1 rmdev -dl (will remove all disks)

If you only want to remove vpaths/disks that don't belong to a volume group you will need to manually remove each vpath and it's hdisks or script it, you can find the hdisks for each vpath by doing lsvpcfg|grep vpathx

When importing them into the new server you shouldn't have to do anything much as long as you know which vpaths belong to a volume group, then it's just

importvg -y volumegroupname vpath

I need to remove 3VGS out of many other VGS. each VG has 10vpaths and 4hdisks in each vpath. this is IBM San Vol Controller.

I am trying to move to SAN from old server to new server.
Please help me with this.
