- Oracle 11gR2
- 2 failure groups - normal reduncancy
- Each failure group associated with a single disk
Failure Group Alpha is one Disk 1 and Failure Group Bravo is on Disk 2
We recently ran into an issue on one of our Oracle servers. One of our disks (let's call it Disk 1/Failure Group Alpha) failed while Oracle was running. When we restarted the server Oracle would not come up because we did not have enough disks to satisfy our redundancy requirements.
How can we recover from this failure?
- Is there a way to tell Oracle to start the instance with a failure group down, we don't care, we will fix the disk issue later?
- Or do we have to pop a new disk in before the instance can be brought up again?
This happened in one our of staging areas and we would like work out what could be done in the future... particularly if a spare disk was not available.
