Kevin,
The following link:.
http://docs.hp.com/en/8988/ASM-SGeRAC-tk.pdf
Is a paper on asm with SGeRAC.
.
The document here:
http://docs.hp.com/en/5971/SG-SGeRAC-EMS-Support.pdf - this is the december
version - i have the october one which states:
Support for Oracle ASM with SGeRAC, requires: SGeRAC A.11.17, Oracle 10g R2,
and ASM disk group
members must be raw volumes managed by SLVM;
.
There are a few others too, on the hp.com site, if you want the references for
those I can send the links over.

Subject: RE: ASM over SLVM
Well SGeRAC is apparently required by the application vendor. In
any case I have gone through loads of docs. I have seen the SGeRAC
support matrix and now 11.17 supports ASM, the requirement is ASM over
SLVM. It is quite confusing, in oracle doc's they say do not use asm
disks in SLVM. However the HP docs state otherwise for 11.17.
Thanks
...Do you have a reference for where it is now recommended to use ASM
over SLVM?
...As for why Oracle docs say not to use SLVM, that is very easy to
understand. Oracle
docs about ASM are about 50% marketing literature and 50% operational
know-how. Oracle
corp attempts to say that ASM is a volume manager and a filesystem but
it is neither.
It is an Oracle segment manager that scatters blocks (not RAID).
