Re: [OSR-devel] Setting the iSCSI Initiatorname

[Michael P. <MP...@Ac...>]

Hi Gordan,

it's the target that causes problems not the initiator. I have also checked against an OpenFiler based target without problems using the same Intitatorname on every Clusternode.
Nevertheless, using different Initiatornames feels "more right" to me. Perhaps the iSCSI Spec. helps here? I don't know.

Br,
Michael

Is this something specific to the HP SAN iSCSI initiator software trying to
be too smart by half in checking initiators? I don't remember having any
problems connecting to iSCSI shares with the shared config between all
nodes on RHEL5 using the distro supplied iSCSI tools.
