It is a Fiber channel connectivity and I zoning has been done, I did mapping and masking for the host on DMX-4 frame.

need more details. What type of storage ? type of connectivity (FC/iSCSI/NFS) ? Do you get errors ..anything ?

so when you go into ESX and try to add storage ..what happens ?

Nothing I see the LUN under both the HBA's but can not format them or use them at all as they are not seen as storage.

I know it sounds wierd but thats how it is.

cool, so once you went to Storage Adapters in the Hardware panel and clicked Rescan, you were able to see the LUN under disk/lun list ? But when you go to Configuration tab and select Add storage, disk/Lun for storage type ..that's where you don't see your LUN ?

Yes you are right. I asked one of our architects from EMC and he was refering to the SPC2 flag too. I guess I will have to enable it as it is not enabled right now.

I hope this resolves the issue.

Thank you very much to both of you.
Why is it that other servers are able to see the storage and not this one only????
If it were the flag causing the issue it should affect all the VMware ESX hosts right?

and one more thing..

Do you think emc141648 needs to be changed as at the end in the notes section it says "This case should stay with EMC until the QLogic HBA sees the devices first. From there, it is a VMware issue".

any thoughts on this one??

what address on the FA is this device mapped to? I remember a while back you had to change a setting in VMware so that it would rescan for devices that are mapped at higher LUN addresses.

NO diffeence at all with all other VMware ESX hosts ?

i might be a silly one ..you did not forget to run symmask refresh after you were done masking your devices ?
