I am installing new HP MSA2212fc. It is connected thru a SAN switch to 2 DL360G4 servers running ESX3.5.
I configured 2 Vdisks on the MSA. Each is showing as controlled by a different controller. When i do a rescan, one LUN is detected (controlled by Controller B) while the other one is not showing.
Any ideas ?
There is the Virtual Disk owner on each vDisk. You can set this to Auto rather than specifying Controller A or Controller B.
This should sort it out. Doing this from memory so appologise if I am not totally acurate.
Thanks for your help, I found an option to change Vdisk onwer to Controller B not to Auto.
When I did this, both LUNs were available.
Does this mean that Controller A is not active or is there anything wrong in the setup ?
Sounds like there is an issue with ControllerA. Are you using 2 SAN switches and connecting the 2 fibre ports on each controller to separate SAN switches?
Could also be a zoning issue on your SAN switch. Do you have both controllers specified in you zone?
I am using one SAN switch configured without zones and both controllers are connected to it.
