disk-shelf-tool

Shelf Tool - CLI tool for managing JBOD disk shelves on Linux / Ubuntu. Designed to make it quick and easy to identify which disks in your system are physically in each shelf and interact with them on a per-shelf basis.

Written for and tested on Ubuntu 16.04, but should work on any recent and similar Debian-esqe distro.

#Dependencies: apt-get install sdparm php5-cli

For non-Debian-like distro's - you'll need your version of sas_blink_disk. This tool uses the /dev/disk/by-id/ directory for discovery, so if your distro doesn't support this then this tool won't work.

Usage:

./shelf-tool <help|list|blink|deps|run> [shelf id] [command]

#Commands:

• help -- displays this message

• list -- lists shelves (green) and their disks (red) -- displays paths as /dev/disk/by-id/X

• list-sdx -- lists shelves (green) and their disks (red) -- Displays paths as /dev/sdX

• blink -- blinks all disks in a shelf

• run -- runs a command on all disks in a shelf interactively, one at a time -- for example, use parted to format or partition disks

#Examples:

List disks in the system, grouped by shelf:

• ./shelf-tool list

Identify a shelf, or find out which disk(s) aren't being detected in a shelf:

• ./shelf-tool blink exp0x00000000000

Run parted interactively on each disk in a shelf (one by one) to create labels and partitions:

• ./shelf-tool run exp0x00000000000 parted

Get a list of drives in a shelf and their parameters (in this case, the model number):

• ./shelf-tool run exp0x00000000000 "hdparm -I" | grep "Model Number|/dev/"

Set all drive in a shelf to spin down if not used (great for backup / infrequently used storage)

• ./shelf-tool run exp0x00000000000 "hdparm -S 120"

#Todo: This project is not actively being developed by me, so over to you Open Source Community...

• Display vendor / SAS enclosure number information for the shelves to make them easier to identify
• List size / vendor and/or partition information next to each disk

No external libraries used, but the heavy lifting is done by Linux, PHP and the sdparm package.
