1 HBA missing in Powerpath
Hi
I have 2 RedHat Enterprise 4 Linux nodes running on a RedHat cluster on a CX300.
In each nodes, there are 2x HBA Qlogic cards.
One of the node, is showing just one HBA card, even though in reality there shld be 1 more HBA card, total 2 HBA cards.
[root@misln01 scsi]# powermt display
Symmetrix logical device count=0
CLARiiON logical device count=6

1 qla2xxx optimal 12 0 - 0 0
A run of scli Qlogic utlity confirm this.

-----------------------------------------------------------------------------
Total QLogic HBA(s) : 2
I have tried to run powermt config, but still its showing 1 HBA card.
What shld I do to get the other HBA card shown in PP without affecting the I/O.
Thanks

There is ~management under Connected Storage groups as green color.

I forgot to mention that this is a 2-node Linux cluster.
Each node having 2 HBA's.
My guess is that the HBA which was greyed out was faulty and replaced with a new HBA which is shown under the ~management.
Can I click on the Reconnect button to refresh the affected node so that the WWN no get refresh with a new WWN no. I check somewhere in this PowerPath forum that this can be done.
Thanks

Somehow the devices on the 2nd HBA is only 2 devices and not 12 as it shld be.
[root@misln01 log]# powermt display
Symmetrix logical device count=0
CLARiiON logical device count=6

I have another red hat enterprise 4 linux server on kernel 2.6 also facing same problem.HBA card is Emulex lpfc. THis is a 2-node veritas cluster.
What shld be the equivalent command for lpfc drivers?
[root@zmy02spc01 emc]# ./lun_scan.sh all
Scanning lpfc HBA instance with scsi host number : 0
Scanning lpfc HBA instance with scsi host number : 1

I've tried, still i cannot get the 2nd HBA.
I even unplug and plug the 2nd HBA, still cannot see the HBA online
My colleague was telling me that she has to reboot the server a few times
in order to get both HBA's online.
Is this a sign that the HBA is bad?
Is there any Emulex utlitity that I can get the HBA online, just like scli in Qlogic.
