Question of understanding

[the_nipper]

Hi all,

please could someone help me and explain, how iSCSI and LUNs are working together (and with VMware ESX)

When I have 2 volumes, each in a seperate target, I give each its seperate LUN. That is clear. The LUN identifies the disk hardware.

With Open-E, I can assign multiple iSCSI volumes to one iSCSI target. For each assignement, I have the LUN input line in the GUI. Must I give the same LUN t o all volumes of the same target, because they represent one disk, or must I set different LUNs, as I had multiple targets?

Thank you,

Robert

You can do this in several ways depends on how you want to present it so each Target will have separate LUNs for management.

I did not see this in the doc but I may have missed it

Vmware does not like having the same Lun numbers globaly
