Creating & Migrating Lun

grshankar — Wed, 05 May 2010 08:31:32 GMT

Dear all, I have few questions
1. How to configure a VA7410 to a new server and present the lun, as the VA is already connected to one of the server.
2. Is there any practice to migrate the lun’s of a volume group to a new server in VA7410?
3. Can we use the vgexport & vgimport for the above one?

Assume a lun of 100 GB from the VA is mounted on a server, umount the filesystem & present the same lun to another server and mount the filesystem.
