Hi All,

We have been trying to install a new HBA card (Qlogic) in the Linux Server ( RedHat Linux AS

2.1- Kernel 2.4.9-e.34summit).
We already have existing 2 HBA cards installed/configured in the system . This new card is of

same make. So drivers/compatibility should not be a problem. Still the OS could not

detect/install this new third HBA card on its own. which I feel it should.

Now my questions to you are ,

1. What do we have to do for OS to detect/configure this third HBA card ?
2. Whether the kernel 2.4.9-e.34summit is not supporting 3 HBA cards at the same time ??
3. Shall I use modprobe , if yes how ?

HBA card is not faulty , as it is well detected in the lates kernel of RedHat 2.4.9-e.65summit.
But somehow we have to get it installed in the kernel 2.4.9-e.34summit.

Please help.

Make sure that the card is actually being detected in the bios. We have some IBM systems that are fussy about where the cards are actually inserted. If I take a QLA2344 and stick it any any slot other than slot 6 in an IBM6217 the sytem will not even boot. On the 2.4 Kernel make sure that you are running the 7.01.01 driver. If you are trying to run with three cards it may wery well not be supported by the hardware and/or kernel. What model of HBA are you using? If you need 6 ports I would go with a QLA2342 and a QLA2344, they are very happy together.

You can get your driver version by first doing a ls /proc/scsi/qla2xxx

and then a cat /proc/scsi/qla2xxx/<port#>

All of that said I'm not sure if 3 HBAs are supported anyway, I have never seen it.
