Comments on How To Create A Fiber Channel SAN Using SCST With QLogic HBA On Linux Debian 6
How To Create A Fiber Channel SAN Using SCST With QLogic HBA On Linux Debian 6 I created this how-to as none of the other instructions on the internet work correctly. This is done specifically for Ubuntu and Debian and is based on the 2.6.32 although with some common sense this should work with any distro and any kernel.

Works great.. One question:Is it possible to create a replicated pair for HA? My thought would be to replicate using DRBD between two identical nodes. The only gotcha would be figuring out how to failover in a hypervisor such as XenServer where there are a number of fields that are used to identify LUNS and SCSI disks.Would love to hear your thoughts.
