RAC ASM storage migration ...
We have a diskgroup with the following configuration:
+DG_DAT_01 (redundancy normal)
FAILGROUP A : disks1, disk2, disk3, disk4
FAILGROUP B: disk5, disk6, disk7, disk8
We want to move diskgroup contents to another storage, we're gonna do:
Setp 1: add new disks to the diskgroup
alter diskgrup +DG_DAT_01 add
failgroup EMC_1 disk 'diskA','diskb','diskc'
failbroup EMC_2 disk 'diskd','diske','diskf' rebalance power 0;
Step 2: Remove the actual disks in use
Step 3: Start rebalance operation.
Our questions:
1 - Can we remove all disks in the same command ?
2 - Can we add all the disks in the same command ?
3 - Is it better to remove one disk at a time ?
