pool_name=pond/vdev_name=id1,sd@n5000c500335dc60f/a"
Status : faulty

Description : ZFS device 'id1,sd@n5000c500335dc60f/a' in pool 'pond' failed to open.

Response : An attempt will be made to activate a hot spare if available.

Impact : Fault tolerance of the pool may be compromised.

Action : Use 'fmadm faulty' to provide a more detailed view of this event.
Run 'zpool status -lx' for more information. Please refer to the associated reference document at http://support.oracle.com/msg/ZFS-8000-LR for the latest service procedures and policies regarding this diagnosis.

2. Replace the faulty or retired device or clear the device error.
For example:

# zpool clear pond c0t5000C500335DC60Fd0
If an intermittent device error occurred but the device was not replaced, you can attempt to clear the previous error.

 

3. Clear the FMA fault. For example:

# fmadm repaired zfs://pool=86124fa573cad84e/vdev=25d36cd46e0a7f49/pool_name=pond/vdev_name=id1,sd@n5000c500335dc60f/a

fmadm: recorded repair to of zfs://pool=86124fa573cad84e/vdev=25d36cd46e0a7f49/pool_name=pond/vdev_name=id1,sd@n5000c500335dc60f/a

4. Confirm that the fault is cleared.

# fmadm faulty

If the error is cleared, the fmadm faulty command returns nothing.
