Hi Maureen, thanks for clarifying that you will be deploying single-instance
Oracle (not RAC) on a Veritas CFS with ServiceGuard - the bundling of the
latter two products is called the HP ServiceGuard Cluster File System for
Oracle, and is part of the HP ServiceGuard Storage Management Suite (HP SG SMS)
family of products.
You are correct in assuming that you do not need to install Oracle CRS as part
of your target stack. If you were to deploy Oracle RAC (releases 10g and
later), then at that time you would need to install CRS.
It is highly recommended that you use Oracle Disk Manager (ODM) to
significantly improve performance of your DB on the CFS (ODM is included for
free) - for a detailed white paper on improving single-instance Oracle on ODM
performance, and how to enable it, please see here -
http://docs.hp.com/en/10404/ODM_SingleinstanceOracle.pdf.
Additional HP SG SMS documents can be located here - http://docs.hp.com -> High
Availability -> SG SMS. A shortcut is
http://docs.hp.com/en/ha.html#HP%20Serviceguard%20Storage%20Management%20Suite.
In addition, the base ServiceGuard docs can be of help, particularly if you are
transitioning from JFS/LVM to CFS/CVM - please see Chapter G in the "Managing
ServiceGuard 15th edition" doc off http://docs.hp.com -> High Availability ->
ServiceGuard - shortcut is http://docs.hp.com/en/B3936-90135/B3936-90135.pdf.
I hope this helps! Thanks! Regards!

Thank you all for your responses. I passed your questions to the
system administrator who came back to me today with some more info.
It looks like we really do not need to install crs since we are not
using RAC. There is something in Service Guard that mentions RAC,
(licensing?) so the system administrator read more into it and thought
that we needed to install crs.
From what I understand, Service Guard and Veritas (VxFS?) are giving
us what we want, a clustered file system and the ability to control
what node a service/application/database runs on. If a node goes
down, the database will automatically come up on another node. It
really is pretty basic.
If anyone is running Oracle on HP-UX, any comments about your setup
would be most appreciated, especially if you are using Service Guard
and/or Veritas...or even crs.
Thanks again for all of your comments!
- Maureen
