Hi
Have a V240 running S8 with SVM 4.2.1 ( +latest patch ) and SFK 4.4.8
( again with latest patches ).
Have 2 QLogic QLA2340 HBAs connected via a SAN fabric ( actually 2
independent fabrics, one per HBA ) to 2 controller channels on a
transtec 6600 fibre array.
Using SUNWqlc ( leadville ) drivers to manage the HBAs ( also tried
QLogic's own drivers and fail over but they give the same problem -
QLogic support then recommended that we don't use their drivers apart
from on Linux as they are not developing for other OS's ).
Using mpxio for the luns on the array which load balances across both HBAs.
Normal course of events, everything's fine, if disable one of the HBAs
( by disabling port on switch ) remaining path is ok and re-enabling
the HBA path works as well.
However, if out any of the array LUNS into a metaset, then if the path
through which SVM issues the SCSI reservation on the LUN is disabled,
it tries to reissue the SCSI reservation through the other path finds
a conflict and consequently the host panics ( as would be expected )
I have searched all the Sun documentation I can find as well as
googled extensively but I cannot find anything which mirrors my
situation exactly - has anyone had similar issues and if so did they
ever resolve them.

PS. using metasets because eventually plan to share these LUNs between
two or more hosts but currently just testing with one host ( one of
the docs I was reading from Sun even suggested use metasets even if
not shared LUNs )
