Comment on Linux SAN Multipathing (HP Storage) by Andreas

Hi Jorge,

please check weather “grep version /proc/scsi/qla2xxx/0″ shows “Driver version x.x.x.x” without “-fo” appended to the version. Otherwise you have enabled the failover mechanism from the QLA-driver.
You can change this setting while changeing “failover = 0″ in “/etc/hp_qla2×00.conf” and running “hp_compile_qldriver”. You will of course have to reload the kernel-module – or even better reboot.

Regards,

Andreas

Hi, I have this situation, but after install Proliant Support Pack (PSP) on my HP Blade 465c, it boots with the new initrd and only see one path for every disk, and with load on the server, the server freze if one HBA goes down. There is a way to see all the path again with the PSP installed?

Hi Thomas

Very well documented procedures. I tested pkg failover on both nodes as well. But when I shutdown the primary node and restart the cluster, the cluster is not coming up its giving error as follows
cmruncl: Validating network configuration…
cmruncl: Network validation complete
cmruncl: Validating cluster lock disk …. Done
Cannot reach node “node1″.
cmruncl failed: No such file or directory

Hello Thomas,

Many thanks for this article. It has just got my disks from an HP SAN configured nice and quickly.

Interestingly, Red Hat’s own DM Multipathing document doesn’t cover some of the configuration steps you mention (e.g. use of kpartx, the /sys/block/sda/device/* files and the /var/lib/multipath/bindings file). Knowing where to look for this information saved me some valuable time.

Thanks again,
Colin
