# Turn off disk's enclosure slot if it becomes FAULTED.
|

|
|
#
|
||
|
|
# Bad SCSI disks can often "disappear and reappear" causing all sorts of chaos
|
||
|
|
# as they flip between FAULTED and ONLINE. If
|
||
|
|
# ZED_POWER_OFF_ENCLOUSRE_SLOT_ON_FAULT is set in zed.rc, and the disk gets
|
||
|
|
# FAULTED, then power down the slot via sysfs:
|
||
|
|
#
|
||
|
|
# /sys/class/enclosure/<enclosure>/<slot>/power_status
|
||
|
|
#
|
||
|
|
# We assume the user will be responsible for turning the slot back on again.
|
||
|
|
#
|
||
|
|
# Note that this script requires that your enclosure be supported by the
|
||
|
|
# Linux SCSI Enclosure services (SES) driver. The script will do nothing
|
||
|
|
# if you have no enclosure, or if your enclosure isn't supported.
|

|
# Exit codes:
|
||
|
|
# 0: slot successfully powered off
|
||
|
|
# 1: enclosure not available
|
||
|
|
# 2: ZED_POWER_OFF_ENCLOUSRE_SLOT_ON_FAULT disabled
|
||
|
|
# 3: vdev was not FAULTED
|
||
|
|
# 4: The enclosure sysfs path passed from ZFS does not exist
|
||
|
|
# 5: Enclosure slot didn't actually turn off after we told it to
