RE: Thoughts on crs installation on HP-UX

I generally agree, with the two notable exception that using SG+CRS gives you the option of a clustered filesystem, something that you don't get with just CRS, and failover interconnects, which I believe you still can't do with CRS. If you don't care about those things though, or just don't want to deal with the added complexity.

Thanks,
Matt

Conversely, I don't know why you'd use SG+CRS if you're doing
active/passive, since CRS by itself is a perfectly respectable HA clustering
solution :). With CRS and ASM-managed database storage, there's nothing
you'd be missing. If you aren't using ASM, though, you'd have to use RAW
devices or some other cluster filesystem since OCFS isn't available on HPUX.
