Solaris MPXIO on a P4500?

Can anyone help or point me in the right direction for setting up SunOS software initiators using MPIO to a P4500 cluster, we cant find any documentation for this, it seems nobody is using solaris and lefthands, most info is for FC MPxIO.

Thanks

We used the information in this Sun Blueprints document

http://www.sun.com/blueprints/1205/819-3730.pdf

We stuck to using IPMP and have had it working successfully on a couple of Solaris 10 clusters for a few months now.

Re: Solaris MPXIO on a P4500?

I too am trying to do this and while I can easily get the volumes connected to my Solaris server, it shows up as 4 different devices. (I have 4 P4500 G2s in my cluster, but I am not sure that correlates though.) I am also very frustrated that there is zero documentation on this.

In my case each has its own ISID, but the same TPGT so they are see individually. Am I missing something on getting multipathing to work on Solaris 10 so it see all 4 of these as the same volume? So with all of the link aggregation we have, it is not using any of it since there is only one session. I have looked at that Blueprint document too many times to count and IMO, it is just not detailed enough where it counts. Plus, it is nearing 6 years old. Is the HP P4500 using MC/S and does Solaris 10 now support this method? I have seen in other docs where as of Solaris 10 update 4 in some and Solaris 10 update 5 in other docs, it will be supported.

Any ideas?
