|title||Missing device in non-replicated configuration|
|description||A device could not be opened and no replicas are available.|

|impact||The pool is no longer available|
|response||No automated response will be taken.|
For an active pool
If this error was encountered while running 'zpool import', please see the section below. Otherwise, run 'zpool status -x' to determine which pool has experienced a failure:
# zpool status -x pool: test state: FAULTED status: One or more devices could not be opened. There are insufficient replicas for the pool to continue functioning. action: Attach the missing device and online it using 'zpool online'. see: https://illumos.org/msg/ZFS-8000-3C scrub: none requested config: NAME STATE READ WRITE CKSUM test FAULTED 0 0 0 insufficient replicas c0t0d0 ONLINE 0 0 0 c0t0d1 FAULTED 0 0 0 cannot open errors: No known data errors
If the device has been temporarily detached from the system, attach the device to the system and run 'zpool status' again. The pool should automatically detect the newly attached device and resume functioning. You may have to mount the filesystems in the pool explicitly using 'zfs mount -a'.
If the device is no longer available and cannot be reattached to the system, then the pool must be destroyed and re-created from a backup source.
For an exported pool
If this error is encountered during a 'zpool import', it means that one of the devices is not attached to the system:
# zpool import pool: test id: 10121266328238932306 state: FAULTED status: One or more devices are missing from the system. action: The pool cannot be imported. Attach the missing devices and try again. see: https://illumos.org/msg/ZFS-8000-3C config: test FAULTED insufficient replicas c0t0d0 ONLINE c0t0d1 FAULTED cannot open
The pool cannot be imported until the missing device is attached to the system. If the device has been made available in an alternate location, use the '-d' option to 'zpool import' to search for devices in a different directory. If the missing device is unavailable, then the pool cannot be imported.
