Assign LUN

sergio_57 — Mon, 20 Sep 2010 06:43:20 GMT

i have a msa2012i iSCSI connect a Windows cluster 2008 (with name HYPERV) with 3 node's, i have configuring a two vdisk on msa2012i (storage0 and storage1). I assign the first volume on vdisk storage0 to LUN 0 on the HYPERV,the second volume to LUN 1 , and so on until 9. Now i have assign to first volume on storage1 to LUN 0 to HYPERV, the second to LUN 1 , and so on.
It's correct ?? or should i assign LUN 10, LUN 11 and so...?
thank

Better way is start the LUN from 1, 2, 3 , 4, and so on..

The same LUN number can be maintained for all the hosts. Suppose 3 LUNs preseting to 3 node hyper-v cluste.. volume1 to LUN1 for all 3 hosts, volume2 to LUN2 and volume3 to LUN3 for all hosts.

ok, i have:
vdisk1 with volume1 mapping to hyperv1,hyperv2,hyperv3 with LUN1
vdisk1 with volume2 mapping to hyperv1,hyperv2,hyperv3 with LUN2
vdisk1 with volume3 mapping to hyperv1,hyperv2,hyperv3 with LUN3
but i have also...
vdisk2 with volume1 and i mapping to hyperv1,hyperv2,hyperv3 with LUN.. (LUN 1 or LUN 4) ??
vdisk2 with volume2 and i mapping to hyperv1,hyperv2,hyperv3 with LUN.. (LUN 2 or LUN 5) ??

ok this for first cluster with node hyperv1,hyperv2,hyperv3.
For a second cluster with node1,node2,node3 , for use a new volume on the same vdisk1 i have to map , for example , new volume 4 to LUN 1 , volume 5 to LUN 2 .....
it 's correct ???

thank you
