Hi,
during testing of OSR in an iSCSI setup, the iSCSI-Target (HP Lefthand)
has problems caused by
using the same Initiatorname on every node.
Here is a patch that uses an extended rootsource syntax for setting an
node-specific Initiatorname.
The syntax used is: <rootsource
name="iscsi://<target-ip>:<port>/<Initiatorname>"/>
Currently this could be CentOS/RHEL specific as the file
/etc/iscsi/initiatorname.iscsi is written.
The patch is against the beta repo.
I hope this could be usefull for someone else.
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.

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

Hi Gordan, Michael,
@Michael: could you please sent this patch as attachement?
for me this looks like a general problem that could be not only related to the
lefthand storage.
Although I didn't have problems using iscsi at least this patch makes life
with iscsi more configurable.
Besides as the iscsi-url we are using is and was never conforming to any
standard I'll go with this and push it upstream. And it does no look like it
would influence the standard behaviour in any way.
Regards and Thanks
Marc.
