rx6600 Linux HBA problem

MartyB — Fri, 29 Feb 2008 20:49:21 GMT

Hello, I am testing RHEL4U5 on one of our rx6600 systems attached to a DMX, but I'm having trouble getting the system to see the presented LUN. I've already asked our DMX admin to double check all zoning/presentation setttings. I have been able to get the SCSI layer to see it:

# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: TEAC Model: DV-28E-N Rev: C.6C
Type: CD-ROM ANSI SCSI revision: 02
Host: scsi1 Channel: 00 Id: 03 Lun: 00
Vendor: HP Model: DG072ABAB3 Rev: HPD5
Type: Direct-Access ANSI SCSI revision: 05
Host: scsi1 Channel: 00 Id: 04 Lun: 00
Vendor: HP Model: DG072ABAB3 Rev: HPD5
Type: Direct-Access ANSI SCSI revision: 05
Host: scsi2 Channel: 00 Id: 00 Lun: 00
Vendor: EMC Model: SYMMETRIX Rev: 5771
Type: RAID ANSI SCSI revision: 02
Host: scsi3 Channel: 00 Id: 00 Lun: 00
Vendor: EMC Model: SYMMETRIX Rev: 5771
Type: RAID ANSI SCSI revision: 02

But I can't get a device assigned. I'm thinking it may be the driver, but I'm not sure. Any ideas? Here's some other info that may be relevant:

If you already rebooted the server, then I had similar problems with a Solaris Host. After I changed a value in the HBA using QLogic SanSurfer, the LUNs where visible.

I don't remember exactly the value, but was something related to "publish any lun visible to host" instead of only those with persistend binding configured.

MartyB — Fri, 29 Feb 2008 23:03:08 GMT

Thanks for the reply Ivan! I think this is what you're talking about, and I believe I already have the correct option enabled:

1: Present targets that are persistently bound plus
any new target(s) (Current)
2: Present targets that are persistently bound Only
3: Bind by World Wide Port Name (Current)
4: Bind by Port ID
5: Commit Changes for this HBA
6: Return to HBA Selection Menu

If you're referring to something else, please let me know!

Re: rx6600 Linux HBA problem

skt_skt — Sun, 02 Mar 2008 03:19:00 GMT

options qla2xxx ConfigRequired=0 ql2xfailover=0

ql2xfailover=0 is to facilitate HBA failover using the qlogic driver. ConfigRequired=0 says all the LUNS discovered in this system will be presented to the OS.
If this value is set to 1, only those LUNS specified in /etc/qla2xxx.conf will be visibile to the OS

Santhosh, thanks for the tip! It appears my modprobe.conf is good, but here it is in case I'm missing something:

I went ahead and commented them out (and rebooted) hoping it'd help, but I'm still dead in the water.

Any other ideas out there??

Re: rx6600 Linux HBA problem

skt_skt — Tue, 04 Mar 2008 18:07:02 GMT

did u rebuld the initrd image(keep a backup)after the change in the modprobe.conf.

mkinitrd -f /boot/initrd-`uname -r`.img `uname -r`After the initrd is rebuilt, reboot the system for the changes to take effect.

Re: rx6600 Linux HBA problem

MartyB — Wed, 19 Mar 2008 14:54:01 GMT

Sorry for the late reply on this. Yes, when I installed the QLogic driver, it automatically rebuilt the initrd for me. Any other things I can try / look at?

Thanks!

i meant you need to rebuild the *.img(take a backup) after the chnages in modprobe.conf.

Do you power path also here? If not ignore.
PP and DM need to be present at the same time.

Nope, no PowerPath installed on this system.

FINALLY! After getting our SAN guy to take another look, there was some zoning issue that he overlooked. It's all good now.

Thanks so much for everyone's advice.
