rx6600 Linux HBA problem

[MartyB]

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:

Thanks!

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]

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!

post "/etc/modprobe.conf"

[skt_skt]

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

[MartyB]

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

# cat /etc/modprobe.conf
alias scsi_hostadapter usb-storage

alias eth1 e1000
alias scsi_hostadapter2 mptbase
alias scsi_hostadapter3 mptscsi

alias scsi_hostadapter5 mptsas
alias scsi_hostadapter6 mptscsih
alias usb-controller ehci-hcd
alias usb-controller1 ohci-hcd
options scsi_mod max_luns=255
install qla2xxx /sbin/modprobe qla2xxx_conf; /sbin/modprobe --ignore-install qla2xxx
remove qla2xxx /sbin/modprobe -r --first-time --ignore-remove qla2xxx && { /sbin/modprobe -r --ignore-remove qla2xxx_conf; }
options qla2xxx ql2xfailover=0 ConfigRequired=0
alias scsi_hostadapter1 qla2xxx_conf

we dont use the install and remove entry

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??

[skt_skt]

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.

[MartyB]

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!
