Each VG will be 2 or 4 LUNs from SVC. I am not worried about the logs and storage pools. Only the DB.

Your Volume groups are made up of 1 or more hdisks provided locally or from the SAN. I've split my VG's into 5 types of VGs Dbvg <- Databases Logvg <-Logs Instvg <-Instance Bkvg <- DB Backup Stgvg <- Disk storage pools And all have 2 hdisks mirrored across two SANs for protection with exception of the stgvg as this is just a staging area for the transient data. This is just one way of doing it. With Two VGs you would just have to structure your Logical Volumes (Filesystems) Across the 2 Volume Groups. If you only have a small amount of hdisks available then you could get away with one Volume Group. Hope that is a little helpful.

We currently have 6 VGs for the DB and 3 VGs for the logs. Each VG contains 1 file system. The DB is about 375GB and the new hardware is a P8. No TSM de-dup. Should I be concerned about the DB setup?
