#VERSION:  0.3.2
#MODIFIED: 17 Jun 2012
#AUTHOR:   Milhouse
#
#DESCRIPTION: Created on FreeNAS 8.0.1-BETA4 with LSI 9211-8i HBA
#             Tested on FreeNAS FreeNAS 8.0.2-RELEASE with LSI 9211-8i HBA
#
#  This script will attempt to stop disks in a ZFS pool connected
#  by a SAS HBA controller, using the camcontrol command. In effect,
#  this is a poor mans ATAIDLE.
#
#  The script is designed to run as a "daemon" process, running
#  constantly from bootup. The idea is that it will consume standard
#  input, which will itself be the output of "zpool iostat n" where n
#  is a time interval, usually 60 (seconds).
#
#  A count (--timeout) is specified as an argument for the script, and this
#  quantity is decremented each time there is no iostat activity, and reset
#  whenever there is iostat activity. When the count reaches zero, the disks
#  will be stopped using "camcontrol stop" (unless the --test option is
#  specified).
#
#  The amount of time elapsed before disks are stopped is calculated as
#  the product of the timeout and the value n specified for zpool iostat.
#  For example, a timeout of 15 and an interval of 60 gives 15 * 60, or
#  900 seconds (ie. 15 minutes). The default timeout is 30.
#
#  By default, disks will be stopped asynchronously (ie. simultaneously)
#  however if this is a problem, specify the --sync option to stop disks
#  in sequence, one after the other.
#
#  If a system has multiple pools, run individual commands for each pool.
#
#  If the script is unable to automatically detect disks/devices, specific
#  devices can be specified using the --devices argument.
#
#CHANGELOG:
#
#  0.1.0: 2011-08-01  - Initial version
#  0.2.0: 2011-09-05  - Tweak CAMCONTROL detection
#  0.2.1: 2011-10-08  - Rewrite device detection to read devices from SQLITE db
#  0.2.2: 2011-11-11  - Log when new disc activity detected after a stop (disable with --nologstart)
#                       Simplify logging.
#  0.2.3: 2011-11-12  - Minor fix for logging.
#  0.3.0: 2012-06-04  - Add support for multiple pools and pool specific devices
#  0.3.1: 2012-06-05  - Minor coding style corrections, remove trailing comma from default pools
#  0.3.2: 2012-06-17  - Fix regression decoding devices and expansion of args
#
#
#USAGE:
#  Execute the script with the -h or --help arguments.
#
#EXAMPLES:
#   zpool iostat tank 60 | sh sasidle --timeout 15
#   zpool iostat tank 60 | sh sasidle --timeout 15 --devices "/dev/da[2-3]"
#   zpool iostat tank 60 | sh sasidle --timeout 15 --devices "tank:/dev/da[1-2] music:/dev/da[3-4]" --pool tank,music
#   zpool iostat tank 60 | sh sasidle --timeout 15 --sync
#   zpool iostat tank 60 | sh sasidle --timeout 15 --test --verbose

-n POWERMODE, --nocheck=POWERMODE
    [ATA only] Specifies if smartctl should exit before performing any checks when the device is in a low-power mode. It may be used to prevent a disk from being spun-up by smartctl. The power mode is ignored by default. A nonzero exit status is returned if the device is in one of the specified low-power modes (see RETURN VALUES below).

    Note: If this option is used it may also be necessary to specify the device type with the '-d' option. Otherwise the device may spin up due to commands issued during device type autodetection.

    The valid arguments to this option are:

    never - check the device always, but print the power mode if '-i' is specified.

    sleep - check the device unless it is in SLEEP mode.

    standby - check the device unless it is in SLEEP or STANDBY mode. In these modes most disks are not spinning, so if you want to prevent a disk from spinning up, this is probably what you want.

    idle - check the device unless it is in SLEEP, STANDBY or IDLE mode. In the IDLE state, most disks are still spinning, so this is probably not what you want.
