44Clears device errors in a pool.
45If no arguments are specified, all device errors within the pool are cleared.
46If one or more devices is specified, only those errors associated with the
47specified device or devices are cleared.

49If the pool was suspended it will be brought back online provided the
50devices can be accessed.
51Pools with
52.Sy multihost
53enabled which have been suspended cannot be resumed.
54While the pool was suspended, it may have been imported on
55another host, and resuming I/O could result in pool damage.

57.It Fl -power
58Power on the devices's slot in the storage enclosure and wait for the device
59to show up before attempting to clear errors.
60This is done on all the devices specified.

62.Sy ZPOOL_AUTO_POWER_ON_SLOT
63environment variable to always enable this behavior.
64Note: This flag currently works on Linux only.
