RedHat Linux and HSG80

[Andrew Diller]

Hello:

I have an HSG80 that I'm trying to use with RedHat.

My quesion is this: using recent RHEL 4/Fedora systems do I need any compaq/hp specific drivers any more?

My Fedora host sees the hsg80 and assigns the luns ( sda and sdb) but all I get when I try and fdisk or otherwise access them are scsi I/O errors.

I know that the SWCC Stream Agent used to be used in the Compaq days- is that still necessary on the newer kernels from RedHat?

Andrew:

Check your connection types on the HSG80. You may need to set them to a different OS. If you can see the disks, then you probably have all the necessary drivers.

OK- I'll try that. I read on some older SWCC docs that you set the type for RedHat to SUN, which it is, but I'll try a number of them.

I was hoping that since the host see the device as a SCSI target that no futher drivers were necessary.

I don't have any access to those STREAM SWCC agents for Redhat.

Also... how is your zoning set up on your SAN switches?

Sometimes improper zoning causes weird errors.

Unfortunately, changin the OPERATING_SYSTEM didn't affect anything.

I've remove all access to the one unit, then added back in just access to the Redhat server.

The unit was just created and is set to RUN.

Whenever I remove and re-load the qla2200 module (to re-scan the fiber) it picks up the CCL luns for both HSG's and the sda, but it spits out about 60 i/o error and buffer errors when 'reading' various sectors of sda.

I have no Zones on the SAN, and the only devices are the HSG80 and the one RedHat host. The switch is a Brocade Silkworm 2800.

Very strange.

I solved the issue: I switched in another QLogic card (this one was SC, the first was copper) and this card seems to work as expected.

I set OPERATING_SYSTEM = SUN on the unit and removed and modprobed the qla2200 kernel module and the LUN from the HSG80 came up fine. I could partition and put a file system on it.

So I'm going to call this card defective. It's the only copper one that I've used, and I'll just continue to stick with the fiber ones.
