Which document you are talking about? We never say 'no more than 2
disk groups per cluster'.

Btw your initial plan seems perfect.

I see a similar question to this has already been posted, but just wondering
if anyone's actually had to configure something like this before.

Subject: More than 2 ASM Diskgroups in a RAC Enviornment with 2 Databases


---- Start ----
Config Details:

2 Node 10gR2 RAC
HP-UX (PA-RISC) 64 Bit, 11.23
Serviceguard 11.17
ASM used as storage option for database and recovery files.

---- End ----

This 2 node cluster will host 2 RAC databases. Looking at the best practices
document for ASM, I see it says that typically you should have no more than
2 diskgroups per RAC cluster.
However, the initial plan was to create 4 diskgroups - 2 for each database.
Just wondering if anyone has done something similar to this, or if anyone
has more than 1 rac database using asm as the storage?
