Re: Oracle 10g ASM Disk Group Question

ASM doesn't know "what disks you really have".

When you add a new disk ( alter diskgroup asm command ) and point to a 50 gig LUN ASM think's it has a new disk.

Most of the benefit of adding 50 gig at a time to the ASM instance is the fact that you are doing it less often than if you were adding 2 or 5 or 10 gig at a time.

Each time you add storage and trigger an ASM rebalance the IO hit is probably considerable as ASM moves around extents to "what it thinks" is a new disk drive. Received on Tue Apr 25 2006 - 11:37:07 CDT
