Re: Virtual Disk Mapping to Linux
In essence each path is assigned a unique name and those are tied together using udev. The DataCenter Linux working group had more documentation on that, but it was gone last time I checked, so unless you know your ways around udev I suggest you just wait a day :)

Re: Virtual Disk Mapping to Linux
The drivers available here:
http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=12169&prodSeriesId=439556&prodNameId=315741&swEnvOID=1080&swLang=8&mode=2&taskId=135&swItem=co-47070-1
contain versions for both 2.4 and 2.6 kernels. If I recall correctly, you have to remember to select the failover option when installing the drivers...
You might also need to ensure that the firmware on the QLogic cards is at the latest release to enable failover support.
Hope this helps,
Cheers,
Rob
