43.Sh DESCRIPTION
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.
48.Pp
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 when there is evidence
54that the pool was imported by another host.
55The same checks performed during an import will be applied before the clear
56proceeds.
57.Bl -tag -width Ds
58.It Fl -power
59Power on the devices's slot in the storage enclosure and wait for the device
60to show up before attempting to clear errors.
61This is done on all the devices specified.
62Alternatively, you can set the
63.Sy ZPOOL_AUTO_POWER_ON_SLOT
64environment variable to always enable this behavior.
65Note: This flag currently works on Linux only.
