[Cross posting to ha-clusters-discuss]
Hi Octave,
Given that iSCSI targets are purely a network thing, i doubt
very much if using them with or without LDoms has any difference.
That leaves the question of how SC/OHAC supports iSCSI disks.
I believe that we (SC) have focused on OpenSolaris/OHAC for iSCSI support
given the rather large number of issues they have on S10. Perhaps
someone on ha-clusters-discuss can shed more light on this question
(both general iSCSI support as well as supporting those as Quorum disks).
Regards,
-ashu
