Migrating Many LUNS to a single LUN with SF in a cluster
I'm working with a group and I am trying to migrate data from an old array to a new storage array. They used SF to expand their volumes 10GB at a time, now they have 50 LUNs in a single volume. I w...
Yes you can do this in SFW without taking the cluster offline - just add the new single LUN on the new array to the diskgroup and miror the volume containing 50 LUNs to it. When the mirror is synchronised, you can remove the old plex (mirror) and then remove the 50 old LUNs from the diskgroup.
You can do all this in VEA - just right click on diskgroup to add and remove disks and right click on Volume and choose Mirror and then add or remove.
I/O to volumes continue during all of these, but the I/O may be slowed while mirroring.
