# UPDATE HISTORY:
|
||||
# 22 Jul 2015: Alastair Munro:
|
||||
# Disk failures need a Enclosure and Bay location so we can get failed disks easily replaced. Thus
|
||||
# changed objectname to this for disk checks.
|
||||
# Disk checks: include the comments field for the eva, so we can easily log a ticket with HP (we
|
||||
# System check: included comments
|
||||
# include eva serial number and DC cabinet location in here).
|
||||
# If check_system and system specified; drop system name from perf data fields and add Gb.
|
||||
# Turn off perfdata for disk shelves; we don't need to graph how many fc ports it has, etc; these rarely change!
|
||||
#
|
||||
# 17 Mar 2016: Alastair Munro:
|
||||
# No --system in the help; I wanted to add this and only discovered it by looking at the code!
|
||||
# Bring back reporting number of disks checked.
|
||||
# Cleaned up error reporting on failed disks.
|
||||
# Added --option and then noemptybays. All disk shelves should be fully populated with disks and all
|
||||
# shelves have the same number of disks. If a disk fails, it may get evicted and this will catch this.
|
||||
# This is part of the check_disks mode. Report warning if bays not full.
|
||||
#
|
||||
# 04 Apr 2016: Alastair Munro:
|
||||
# notinstalled is not a valid state for fans; especially for disk shelves. Thus alert on this.
|
||||
# check operationalstatedetail is not _ok. Sometimes objects report good but the detail is not _ok (eg _attention).
|
||||
# for disk enclosure, advise enclosure name and state before printing number of sensors, fans, etc.
|
||||
#
|
||||
# 10 May 2016: Alastair Munro:
|
||||
# check_controllers: powersources searching for key status rather than state. Now identifies failed/missing power supplies.
|
||||
#
|
||||
# 20 May 2016: Alastair Munro:
|
||||
# noemptybays not working as expected; tweaked to count disks rather than highest disk.

||||
