What is the documentation for adding and removing disks to an ASM Diskgroup. New disks were provisi
What is the proper procedure for removing a few of the disks to an existing ASM Production diskgroup?
Here is the scenario:
1. Running low on space, requested 2 200GB(DATA_05,DATA_06).
Volumes in DATA diskgroup are 200GB and currently have (DATA_01 - DATA_04)
2. So when the disks were presented provisioning did not show size and added the disks to the diskgroup. I know have DATA01-DATA06
3. However, once balanced and checked, I noticed that they inadvertently gave me 2@100GB versus 2@200GB.
4. So I now have a mix of 2@100GB and 4@200GB … per oracle best practice …. These should all be @200GB
5. So requesting the Linux team to present me new 2@200GB as DATA_07 and DATA_08 and adding them to the cluster is a alter diskgroup add ...
