MSA2012i LUNs not visible

jdudmesh — Tue, 31 Mar 2009 06:47:11 GMT

I've got an MSA2012i which has had 6 disks and 3 LUNs running quite happily got the last 3 months.

Last week I hot added an additional 6 disks and 3 LUNs and although everything appears to be configured correctly, the LUNs are not visible to any of the iSCSI initiators I point at it. The original 3 LUNs are still visible and working correctly.

I knew it had to be something simple!

That's fixed it - thanks very much.

I should add that it was necessary to remap the volumes as all the mappings get deleted when the vdisk owner changes.
