Hi all,
does anybody know how i can make the SLES9 to recognize SCSI LUNs >= 8?
I have set up a SLES9 (for IA64 architecture) on a DELL 1850 hardware, which has to be connected to a HP EVA3000 SAN via two Qlogic HBAs ql2342.
The shipped drivers for the Qlogic HBAs work fine, I'm just not able to recognize virtual disks presented with LUNs >= 8, which I think is due to the module scsi_mod.
I tried the parameters "max_luns=128" and "max_reported_luns=128" for module "scsi_mod" both in /etc/modprobe.conf.local and in /boot/grub/menu.lst, but still only LUNs < 8 are recognized by the driver.
The qla2*-Modules don't seem to have any options regarding # of LUNs.
The HBA's BIOS is configured to see 128 LUNs.
It is a fresh installation with all the latest updates from Suse as of 20.1.2005.
/proc/cmdline contains:
root=/dev/sda6 max_luns=128 max_report_luns=128 vga=0x317 selinux=0 console=tty0 resume=/dev/sda2 elevator=cfq splash=silent

I don't know, but the first place I looked is the HP SAN Design Guide http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00093931/c00093931.... Per the table on page 153, Linux can see 32 LUNs per target. Unfortunately, the whole book seems to revolve around 2.4 kernel based systems. (Does HP support SLES9?) Your issue should definately fall within your SUSE support contract. I would contact them. Also Lars Marowsky-Bree works for SUSE and is helping SUSE get FC multi-pathing up to speed for 2.6 inclusion. He is therefore participating on the dm-devel mailing list. You could post there and see if you get any help. Greg -- Greg Freemyer
