Linux - FC Card - LUNs are not visible

Hi,

I have a Lpr2000 system with Linux 7.2 insalled (2.4.21-4.ELsmp). I have inserted a HP Tach TL Fibre Channel HBA to one of the PCI slots. After reboot the system is able to recognize the card using the "lspci" command,

[root@lx3 linux-2.4]# lspci
00:00.0 Host bridge: ServerWorks CNB20LE Host Bridge (rev 06)
00:00.1 Host bridge: ServerWorks CNB20LE Host Bridge (rev 06)

01:05.1 SCSI storage controller: LSI Logic / Symbios Logic 53c1010 Ultra3 SCSI Adapter (rev 01)
[root@lx3 linux-2.4]#

The host is connected to a VA7100 array via a FC switch. But it is unable to see any LUNs. "cdrecord --scanbus" shows only the internal disks. Is it required to recompile the kernel or do I have to load any kernel modules using insmod? Pl. help

Thanks,

Similar card on HP-UX works fine. The model is (from HP-UX)

swlist | grep -i fibre
FibrChanl-00 B.11.11.09 PCI/HSC FibreChannel;Supptd HW=A6
684A,A6685A,A5158A,A6795A

Change the slot for that card, is it not an interrupt issue ?

I dont think it is an interrupt issue as it is a PCI card. I also tried changing the slot ..

Is this an A6826A card? That is the only HP manufactured card that is supported on Linux.

Their other cards are only supported under HP-UX.

...dug down a little more, seems that the A6826A isn't even a true HP card. It appears to be OEM'd from QLogic since it uses the qla2x00 driver.....

It is a A5158A PCI FC card. I think as you said it is supported only under HP-UX.

The A5158A card is an HP9000 card. However, when placed into a Windows machine, the card is recognized as a D8602B. The cards are identical, except the A5158A is much more expensive (for obvious reasons)

There are no linux drivers for that card. You will need to get a different card, or run Windows.
