Looking to see if someone has experience with the following scenarios.

Solaris 9 (no VxVM)

Host A & B have primary devices presented, sort of a poor man's
cluster. These are also R1 devices of SRDF.
Host C has clone devices of the primary devices presented.
Host D has R2 devices presented of the SRDF.

>From what I have found metaset may be an option however it seems you
can only have two hosts in a metaset but I have three. I am looking
to automate the process whether it's using metasets or manually
modifying the metadb on each of the target hosts (C & D).

If this were VxVM it would be very straightforward but I am not too
experienced with SVM.

Advice appreciated.
