Replacing an Oracle ZFS Storage ZS3-2 HDD or SSD

HDDs and SSDs are hot-swappable and can be removed and installed while the storage controller is running without affecting other hardware capabilities. Use the following procedure to replace an Oracle ZFS Storage ZS3-2 HDD or SSD.

Note:

If you have more than one failed drive, replace only one drive at a time. Removing more than one drive in quick succession causes a hardware/pool fault. Also, do not perform a pool configuration operation while a disk firmware upgrade is occurring. To check if an upgrade is in progress, from the Maintenance BUI menu, select System, or navigate to maintenance system updates in the CLI.

Identify the faulted HDD or SSD.
- If you are not physically at the system, from the Maintenance BUI menu, select Hardware, and open the detailed view of the controller. The faulted drive has either an amber or a blue-on-amber (ready to remove) status icon. Note the ID of the faulted drive. Click the entry for that drive in the table to highlight the location of the drive in the controller illustration. To view details about the faulted drive, click its information icon and then click Active Problems.
- If you are physically at the system, the amber Service Action Required indicator on the HDD or SSD should be lit. Additionally, you can click the locator icon in the BUI to light the locator LED on the faulted drive.
Verify that the faulted drive is ready to be removed.
Caution:
Removing the drive before it is ready to be removed can result in loss of data.

Use any of the following methods to verify that the faulted drive is ready to be removed:
- In the BUI:
  - The status icon for the faulted drive in the detail view in Maintenance: Hardware has changed from amber to blue-on-amber.
  - The Component Details information window (click the information icon ) for the faulted drive shows Yes as the value for the Ready to remove property.
- In the CLI (and RESTful API), the value of the readytoremove property for the faulted drive is true:
```
hostname:maintenance chassis-000 disk-001> get readytoremove
                 readytoremove = true
```
At the front of the controller, pinch the air filter's left and right release levers inward [1].
Pivot the air filter forward and lift if out of the chassis [2].
Press the release button of the failed drive, and pivot the release lever open to the right.
Grasp the release lever and pull the drive out of the drive slot.
After at least 30 seconds, from the Maintenance BUI menu, select Hardware, and click the right-arrow icon on the system controller to verify that the software has detected that the drive is not present.
Align the replacement drive with the drive slot.
Press on the release button to slide the drive into the chassis until the release lever moves slightly inward.
Press the release lever fully closed with a click, securing the drive into the drive slot.
From the Maintenance BUI menu, select Hardware. Click the right-arrow icon for the controller, and then click Disk to verify that the online icon is green for the newly installed drive.
If a fault does not self-clear, see Repairing Active Problems.
