We recently moved moved our stoage and they assigned new to LUN to our host, but in VG it is holding the old LUN. We are running windows 2008. How do we remove the old lun and add the new LUN to the VG?
Did you had a look at Storage Foundation administrators guide ?
If yes, did you found the answer there ?
I could find an answer in guide to what you are looking for :)
Once the new lun is presented to Windows, go into VEA and connect to the server. Expand Disks on the left hand side to find the new disks. Online the disk/lun and initize it as needed. Right click on the new disk/lun and select "Add Disk to Dynamic Disk Group...". Follow the wizard to add it to the disk group.
From there I'm guessing that you will need to mirror or subdisk move the volume(s) to the new disk/lun.
Once the old disks no longer have any volumes or logs on them, you can right click on them and select "Remove Disk from Dynamic Disk Group..). Then it is just a matter of unzoning them from the server.
