Re: RAID and Oracle Databases

Last week, I went from an all RAID5 to partial Raid5 and Raid1. This was acomplished by copying the data to a temporary storage device, then reconfiguiring the RAID, then restoring the data back onto the RAID. After this was done, I had to rename the datafiles to place them on thier corresponding RAID drives. I'm not familiar of the logic behind having 5 drives on RAID1, I didn't know it was possible. You can always use the 4 drives in RAID1 and if possible, the extra drive as a "dump" drive to store your backups (you should keep a copy on tape as well) and other stuff.

Anyway...Good luck to you and to battle the Budget Gods, just have the database crash at low peak times, and lie to them it was the lack of drive space that caused the crash. (By the way, this is not a good idea and should not be taken seriously)
