Expand storage capacity and replace disks in Oracle Database Appliance.
Topics:
Depending on the available drives, you can expand Oracle Database Appliance X6-2S, X6-2M, or X6-L storage to add NVMe disks or replace existing NVMe disks.
Use the ODAADMCLI commands to perform appliance storage maintenance tasks, including perform storage diagnostics and collect diagnostic logs for storage components.
Changing NVMe Storage Disks
The default configuration for Oracle Database Appliance X6-2S or X6-2M includes two (2) NVMe disks. You can expand storage by adding two (2) additional disks for a total of four (4) NVMe disks. When you expand storage, you must add both NVMe drives, adding just one is not supported.
The default configuration for Oracle Database Appliance X6-2L includes six (6) NVMe disks. You can expand storage by adding three (3) disks for a total of nine (9) NVMe disks. When you expand storage, you must add all three NVMe drives, adding just one or two is not supported.
Oracle Database Appliance uses special commands to add or remove NVMe storage.
WARNING:
Pulling a drive before powering it off will crash the kernel, which can lead to data corruption. Do not pull the drive when the LED is an amber or green color. When you need to replace an NVMe drive, use the software to power off the drive before pulling the drive from the slot. If you have more than one disk to replace, complete the replacement of one disk before starting replacement of the next disk.Drive LED Indicators
Each NVMe drive slot has a light-emitting diode (LED) indicator indicating the disk status:
Green LED: OK/Activity. Disk is working normally. It is not save to pull the drive when the green indicator light is on.
Amber LED: Service needed or there is a critical warning. It is not safe to pull the drive when the amber indicator light is on.
Blue LED: The disk is powered off and it is safe to remove the drive from the system.
