The "DGC RAID" will be recognized as a emc asymmetric array and use
emc vendor specific failover mode, "DGC VRAID" won't be recognized.
I heard of that EMC Clariion supported ALUA, solaris mpxio should work
with it by using ALUA failover mode. If you don't want to use ALUA mode
and want "DGC VRAID" being recognized as some emc asymmetric failover
type, you may need to go thru RFE, solaris mpxio certification process.

I believe the Clariion array has default setting in MPxIO.
I'll check with the developers and get back...

I am not sure what you mean here. The failover mode is the same (type
1). Its just the device identification changed from "DGC RAID" to
"DGC VRAID"

mpxio had knowledge of the "original" clariion failover modes. If a new one
has been added then it would have to be re-coded to know of the new mode, or
probably in this case, the raid type.
I'd have to go dig through some of the code but if you know the name of the
emc asymmetric failover module - I think they're all listed in
scsi_vhci.conf - you could try and use that mode for the new LUN ID instead
of trying to fake it out as a symmetric LUN.
Of course mpxio already knows how ALUA failover works so if your array came
up in ALUA mode mpxio should see it out of the box.

to clarify I currently use mpxio with clariion raid5 luns in failover
mode 1, so why do I need to use failover mode 4 (ALUA) for raid6 luns?

Is there a way to make it work without enabling ALUA? I really dont
want to do that.

I am having a problem configuring a lun (raid-6) from EMC clariion
under
mpxio.
the raid-6 luns have a different id than raid5 (DGC VRAID), so I
had to add the following to scsi_vhci.conf:
device-type-scsi-options-list =
"DGC VRAID", "symmetric-option";
symmetric-option = 0x1000000;
Trying to fake out mpxio by telling it that the Clariion is a symmetric
array is a bad idea. Put it into ALUA mode, take out the bits above, and
it
should work out of the box.
