Oracle RAC - Linux Server on VMAX
Hi All,
We have a requirement to connect a two node Oracle RAC to VMAX. The DBA needs a dedicated LUN to Node#1, another dedicated LUN to Node#2, and a shared LUN for RAC for both nodes. To fulfill this requirement, we will need to create 3 different Views as follows:
- One view for Node#1, which has the initiator group for Node#1 HBAs
- One more view for Node#2, which has the initiator group for Node#2 HBAs
- Another view for both nodes, which has the cascaded initiator group containing the HBAs of both nodes.
Can somebody confirm if this is the right configuration or there is any other way to fulfill this requirement? The nodes will run Linux 6.x.
Thanks in advance..

We have not done it yet but this is the design I came up with:
Two Masking views:
- host1_MV
- host2_MV
host1_MV contains
- host1_IG
- our standard port group for the server based on location
- parent storage group that is host specific which contains
- host specific storage - host1_HSG
- cluster storage - host1_CSG
host2_MV contains
- host2_IG
- our standard port group for the server based on location
- parent storage group that is host specific which contains
- host specific storage - host2_HSG
- cluster storage - host2_CSG
Can someone comment on whether this design would work (fairly sure it will) and more important the pros and cons of each design. We considered both designs but this one seemed to fit our needs better.
too complicated for my liking.
MV1 - host1 initiator + host1 storage group + port group
MV2 - host2 initiator + host2 storage group + port group
MV3 - host1 initiator group + host 2 initiator group + "shared devices" storage group + port group.
need to add individual devices just drop them in to host specific storage group, need to add shared ASM devices just drop them into "shared devices" storage group.

that's exactly what we do in our shop. Cascaded initiator group will contain initiator groups for individual nodes.
