Go to Solution1 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

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

- Hi Conor
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 - After doing reconnect of the HBA, i went to the host and did a powermt config.
Somehow the devices on the 2nd HBA is only 2 devices and not 12 as it shld be.

1 qla2xxx optimal 12 0 - 2 0
2 qla2xxx optimal 2 0 - 0 0 - That¿s a good sign, at least the HBA is showing as logging in. You may need to rescan for new devices at the OS level, there are Qlogic rescan scripts available as part of their driver package, personally I think a reboot is the most consistent way of picking up the devices.
