Dear erman,



External redundancy

Oracle ASM does not provide mirroring redundancy and relies on the storage system to provide RAID functionality. Any write error causes a forced dismount of the disk group. All disks must be located to successfully mount the disk group.

We are using raid 5,do we need to take any manual action if any of the disk in external diskgroup is lost?

How does it behave for raid 10?
We are having voring disk also inexternal redundancy with raid.

Pls advise

Thanks,
Satish
