Issues with 3ware card (9550sx) and centos 4.6?

Post by bwragg » 2008/09/02 03:17:19

Hi all,

I've been running a system on centos 4.4 x86_64 and last night we did a yum upgrade to 4.6. Just before I restarted the server I wanted to check if there is any issues with the 3ware (9550sx) support in 4.6? I'm a little scared that I'm going to reboot and the new kernel isn't going to be able to see the controller and raid packs. I've read dozens of threads on this and can't get a clear answer.

When I do a cat /sys/class/scsi_host/host0/stats it shows we are currently running "3w-9xxx Driver version: 2.26.04.010" which I beleive is the version that came with 4.4. Will this just work with the new kernel?

when I do a "locate 3w" I can see 3w-9xxx.ko and 3w-xxxx.ko files in the /lib/modules/2.6.9-42.0.3.ELsmp/kernel/drivers/scsi/ directory (the current kernel) and the same files in the /lib/modules/2.6.9-67.0.22.ELsmp/kernel/drivers/scsi/ directory.

Does this show that the 4.6 kernel has these drivers installed? Or do I need to compile/install soem new ones?

Thanks

If it fails to boot, just boot the older kernel.

Thanks gerald_clark.

The server is physically located about 400kms away so I do everything remotely, hence I was concered I wouldn't be able to select the other kernel at boot time.

This morning I rebooted it and all is fine. So for the record, despite what the 3ware site seems to indicate, the 9550sx cards are supported on Centos 4.6 (well at least if your on 4.4 and do a yum update to 4.6; don't know what happens if your doing a fresh 4.6 install)

Thanks again.
