This topic applies to XInsight-managed systems running QSM 4.2 or later, XEVO 3.2 or later, or KSM 1.1 or later.

The Disk page displays the drives installed in the controller head and connected expansion units. The page provides each drive’s location, status, health, usage, interface, type, speed, capacity, and model, along with drive maintenance and security operations.

Note: JBOD drive information is available only when a supported JBOD expansion unit is connected and detected by the storage system. Systems without a JBOD display only the drives installed in the controller head.

Go to Storage > Disk. Select an array from the Array panel to display its drives. Select one or more drives from the Disk List before choosing an available action. The availability of each action depends on the selected drive’s type, usage, status, and supported features.

Disk List #

Select an enclosure to view its drives. Select one or more drives to perform the available disk actions. Actions that do not apply to the selected drives are disabled.

The disk list displays the drive location, operating condition, usage, hardware information, and encryption status. The following fields provide additional information:

• Status: Displays the current operating status of the drive.
• Health: Displays the current health condition of the drive.
• Usage: Displays how the drive is currently being used, such as whether it is free or assigned to a storage resource.
• Speed: Displays the interface connection speed of the drive.
• Block Size: Displays the logical block size of the drive in bytes.
• Encryption: Displays the supported drive encryption type.
• SED Status: Displays the current Self-Encrypting Drive (SED) status.

Hot Spare #

Use Hot Spare to assign an eligible free disk as a spare. If a disk in the protected disk group fails, the system can use the spare disk to rebuild the data.

Select a free disk, and then click Hot Spare. In the Spare Type list, select one of the following options:

• Global Spare: Makes the disk available to any compatible disk group in the system.
• Dedicate Spare: Reserves the disk for the disk group to which it is assigned.

Click Apply to save the setting.

Note: The Hot Spare button is available only when the selected disk is free and meets the requirements of the applicable disk group. A spare disk must have sufficient capacity and be compatible with the disks it protects.

Set as Free Disk #

Returns an eligible drive to the free-drive state so that it can be used to create or expand storage resources.

Select the drive, click Set as Free Disk, review the confirmation message, and confirm the action.

Warning: If the selected drive belongs to a storage pool, setting it as a free disk removes the drive from the pool. Verify the pool configuration and redundancy before continuing, as removing the drive might cause the pool to fail.

Clear Read Error #

Clears the recorded read-error condition and resets the applicable failed status after the underlying drive issue has been resolved.

Select the affected drive, click Clear Read Error, and confirm the action.

Clearing the error record does not repair a defective drive. Check the drive health and replace the drive if read errors continue to occur.

S.M.A.R.T. #

Displays S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) information reported by the selected drive. Use this information to evaluate drive health and identify indicators of a possible drive failure.

Select a drive and click S.M.A.R.T. Review the available attributes, and then close the pop-up.

Instant Erase #

Securely erases a supported drive by using its built-in erase capability.

Select an eligible drive, click Instance Erase, and confirm the warning to begin the erase process.

Warning: Erasing a drive permanently removes its data and cannot be undone. Verify that the correct drive is selected and back up all required data before continuing.

The action is available only for supported drives that are not currently in use.

Firmware Upgrade #

Updates the firmware of a supported drive.

Important: Firmware upgrades for drives assigned to a storage pool require the pool to be offline. Because taking a pool offline is not currently supported in XInsight, contact QSAN Support at support@qsan.com for assistance with firmware upgrades.

Drive Indicator #

Changes the slot indicator of the selected drive from gray to blue to help locate the physical drive in the enclosure.

Select one or more drives and click Drive Indicator to turn on their indicators. Click Drive Indicator again to return the indicators to gray.
