Pinned topic Redhat 6.2 and LNXALUA
Is there any additional configuration needed with multipath? Out of the box (and what is documented in the install guide), multipath is using the scsi_dh_rdac handler. Should it instead be using the scsi_dh_alua handler?
Right now, this seems to just work -- unless I pull a cable to simulate a path failure. A couple of systems with a forgotten link failed to find any LUNs on the associated DS3500 when it booted; I would have thought ALUA would allow the host to find everything through the existing link... I'll be trying identify all the failure modes, but first I thought I'd check if my configuration sounds sane.
(In the past I've used the RDAC drivers, but I'd like to avoid a solution that requires kernel modules to be compiled everytime I update the kernel -- although I'll need to do a little bit for GPFS.)
Thanks for the help.

Have the same issue:
Nov 07 12:38:24 | sdh: alua not supported
Nov 07 12:38:24 | sdg: alua not supported
on ubuntu 13.04
although host type is LNXALUA...
