  Add NVMe storage to an Oracle Database Appliance X9-2L. Note that the Oracle Database Appliance X9-2S does not support additional storage.

Add disk storage in an Oracle Database Appliance X9-2-HA storage shelf.

The Oracle Database Appliance X9-2-HA storage shelf partially-populated base configuration supports storage expansion with either 7.68 TB SSDs (available in six-packs) or 18 TB HDDs (available in an eighteen-pack). Depending on your initial base storage shelf configuration, there can be up to eighteen expansion slots. These slots are labeled 6-23 as seen from the front of the system (callouts 6 through 23 in the following illustration).

Description of the illustration gxxxx-x8-2ha_optional_shelf_drives_top.jpg

• Upgrade options:

  • For a high performance shelf, you can add up to eighteen 7.68 TB SSDs (available in six-packs). You can add storage with the system running and use the appliance CLI software commands to expand the storage configuration.

  • For a high capacity shelf, you can add eighteen 18 TB HDDs (available in an eighteen-pack). You must power off the appliance, add storage, then re-image and redeploy the appliance software. This is required to reconfigure the appliance from the default high performance mode to high capacity mode.

• Expanding the base configuration storage shelf with 7.68 TB SSDs for high performance. The base configuration has slots 0-5 with 7.68 TB drives for DATA/RECO. Expansion SSDs are available in six-packs and are populated in shelf storage slots from the bottom up to also be used for DATA/RECO, as follows:

  • The first six expansion drives go into slots 6-11.
  • The second six expansion drives go into slots 12-17.
  • The third six expansion drives go into slots 18-23.

  The following illustration shows the expanded drive configuration for 7.68 TB SSDs.

• Expanding the base configuration storage shelf with 18 TB HDDs for high capacity. When expanding the storage shelf with HDDs, the base configurations SSDs will be used for FLASH and the HDDs will be used for DATA/RECO. Expansion HDDs are available in an eighteen-pack and populate the empty shelf storage slots (slots 6-23).

  The following illustration shows the expanded drive configuration for 18 TB HDDs.

• Once you expand storage to support additional disks, you cannot revert to the base configuration (no drives in slots 6-23).

• If you plan on adding another storage shelf, it must be populated identically to your first storage shelf.

• The odaadmcli commands listed here must be run as the root user.

1. Do one of the following:

   • If you are adding 7.68 TB SSDs to the storage shelf, leave the appliance powered on and proceed to the next step.

   • If you are adding 18 TB HDDs to the storage shelf, power off the appliance and proceed to the next step.

2. To install the new drives into the storage shelf, do the following:
   1. Remove one of the empty slot drive filler panels by pressing its release button [1] and removing it from the drive slot [2] as shown in the following figure.

      Note:

      Replace filler panels with drives one at a time to ensure proper storage shelf chassis cooling.

      
      Description of the illustration g5703_de3-24c_drive_removal1.jpg
   2. Open the drive lever of the new drive by pressing the release button on the drive.
   3. Slide the new drive into the drive slot [1] until it engages with the backplane connector and then close the lever to fully seat the drive and lock it into place [2] as shown in the following figure.

      Check that the drive is locked in place and flush with the other drives.

      
      Description of the illustration g5704_de3-24c_drive_replacement1.jpg
   4. Repeat steps a through c until all of the new drives are installed in the storage shelf.
3. Do one of the following:

   • If you added 7.68 TB SSDs to the storage shelf, check that the OK indicator on each new drive is steady green to indicate that it is ready. Then expand the system storage to include the new drives by typing the following command from the primary server node (node 0):

     # odaadmcli expand storage -ndisk number_of_disks -enclosure 0

     Where number_of_disks is the number of disks being added. The system will then detect and use the new storage. It can take up to 12 minutes to update the configuration. For additional storage commands, refer to the Deployment and User's Guide.

   • If you added 18 TB HDDs to the storage shelf, power on the appliance, then re-image and redeploy the appliance software as described in the Deployment and User's Guide.

4. If you are also adding a storage expansion shelf (can only be added to a system with an identically and fully populated storage shelf), you can do so after successfully completing the previous step.

   Refer to the Oracle Database Appliance Owner's Guide for information on installing a storage expansion shelf into a rack.

   Refer to the Oracle Database Appliance Deployment and User's Guide for information on cabling and storage expansion commands for a storage expansion shelf.

Replace a storage disk in an Oracle Database Appliance storage shelf.

1. Locate the failed drive on the front of the storage shelf.

   Look for the drive with its Service Required indicator and/or Ready-to-Remove indicator lit.

   Caution:

   Equipment damage. Do not remove a drive unless you have an immediate replacement.

2. Remove the drive by pressing the release button [1] to release the drive lever and then, rotate the lever open and, grasping the drive body, slide the drive out of the storage shelf [2] as shown in the following figure.

4. Slide the replacement power supply module into the chassis.

   When fully installed, you should hear a click of the release lever returning to the locked position.

5. Plug the power cord into the new power supply and attach the power cord tie strap to the power cord.
6. Place the power supply on/off switch to the "I" on position.

   The Power/OK status LED should be a steady green, and all other indicators should be off.

Replace an IO module in an Oracle Database Appliance storage shelf.

Storage Shelf SAS I/O modules are fully redundant and can be replaced while the appliance is running.

Note:

After a physical insertion or removal action of a storage component (such as a disk or SAS cable), you should wait before performing the next action to allow the system software to fully process the event. This could take up to 3 minutes to complete.

Example figure showing the DE3-24C:

Description of the illustration g5499-x6-2ha_storage_shelf_iom_callouts.jpg

Callout	Description
1	I/O module locking levers
2	I/O module 1 (top)
