Solaris

often a geocluster is a good example for a local only storage...

I understand geocluster to require data replication using one of AVS, TrueCopy or RDF.

Thanks guys, I do have some knowledge on the AIX's LVM work. Eventually, did the solaris behave in such so.

When there are 2 storages (Storage1 and Storage2). On cluster point of view, only LV can be seem; these regardless on which Pyshical Storage (Storage1 and storage2) having issue. Is that concept correct?

| Node1(PRI) | |Node2(SEC) |

v v

|Logical Volume| <----- Cluster concern

--------------------------------------------------------------------------
------------------ -----------------
| storage1 | mirror |Storage2 | <---- Correct?

In your drawing (please add code tags for it to be readable), there is a single mirrored storage.
