Viewing Pool and Device Status (BUI)

You can check the status of pool and component devices. If there is a problem with a pool, details about device status will also be listed.

1. From the Configuration menu, select Storage.
2. Click on a pool to select it and see more details.

   Refer to the following table for a description of the pool status.

   Pool Status	Description
   Online	A pool that has all devices operating normally.
   Degraded	A pool with one or more failed devices, but the data is still available due to a redundant configuration.
   Faulted	One or more component devices are offline and there are insufficient replicas to continue functioning.
   Offline	A pool was explicitly taken offline.
   Unavailable	A pool with corrupted metadata, or one or more unavailable devices and insufficient replicas to continue functioning.
   Exported	A pool is active on the cluster peer and is ready for a cluster failback to occur.
   Retention	A pool has at least one actively retained file with the mandatory file retention policy. The retention status is also listed with the timestamp of the last or latest file retained within any of the pool's filesystems with mandatory retention, and "(expired)" is displayed if that time has passed. The number of filesystems with mandatory file retention and their files is also displayed.

3. View pool encryption properties.
   • If the appliance is at software release OS8.8.0 or later and the "Enable Pool Encryption" deferred update is applied, an ENCRYPTED column is displayed. For more information, see Enable Pool Encryption Deferred Update in Oracle ZFS Storage Appliance Customer Service Manual, Release OS8.8.x.
   • If a pool is not encrypted, then the ENCRYPTED column is blank.
   • If a pool is encrypted, then a lock icon is displayed in the ENCRYPTED column, and hovering the mouse pointer over the lock icon displays the encryption type.
   • If the selected pool is encrypted, then information about the encryption type, keystore, and key name is shown. See Encryption Properties.
     • If the value of the Key Status field is unavailable, then the key has been deleted. In addition, an indicator is displayed to the right of the lock icon and shows that the key for this pool is deleted.
     • If the Key Last Update field is blank, then the key value has not been changed since the pool was created.
4. View the selected pool's device statuses under the Device Status section.
   Refer to the following table for a description of the device status.

   Device Status	Description
   Online	The device is online and functioning. You may not see this status, and instead see the message "No device faults have been detected in the storage pool."
   Degraded	The device is not in an optimal state. Either it is expected to fail soon, or a spare has not finished resilvering yet.
   Faulted	The device is faulty; more information can be found in the maintenance logs.
   Offline	The device was explicitly taken offline; no reads or writes will occur to this device until it has been onlined.
   Removed	The device has been physically removed.
   Hot Spare	This spare device is actively being used as a data disk in the pool as a replacement for a device that failed.
   Unavailable	The device could not be opened or the pool could not detect this device.

5. To see more detailed pool and device error information, do the following:
