OpenSolaris/OpenIndiana utility to manage drive and map wmn device name (c1txxx) to real drive using lsi sas controller — Read more

This script will hopefully make your life easier if you use ZFS on OpenSolaris/OpenIndiana with LSI controllers and some kind of backplane.

It can:

  • list connected drives, and see the mapping between wmn device name (c1txxx) and their physical location (controller, enclosure, slot);
  • turn the error led of a drive on and off (for easy identification of the drive in large enclosures with many disks);
  • be used as a pipe to enhance the output of programs like iostat to annotate disk information with the location of each disk.

It's a work in progress. It works for me, but I don't have the time to polish or clean it up; so if you want to add your favourite feature or fix some nasty bug, feel free to contribute.

Requirements

You have to get the sas2ircu tool. Install it in /usr/sbin, or edit the path in the file). An outdated revision is available here.

There is some work in progress for smartmontools support.

Usage & Available Commands

Everything happens through a CLI:

# ./diskmap.py 
Diskmap - berilia>

You can also run individual commands directly when invoking the program:

# ./diskmap.py ledoff all

discover

You need to run discover whenever the layout has changed (disk have been added/removed). It will populate a cache, which will in turn be used by other commands.

Example:

Diskmap - berilia> discover
Warning : Got the serial 5629293 from prtconf, but can't find it in disk detected by sas2ircu (disk removed/not on backplane ?)
Warning : Got the serial 5629293 from prtconf, but can't find it in disk detected by sas2ircu (disk removed/not on backplane ?)
Warning : Got the disk /dev/rdsk/c3t0d0 from zpool status, but can't find it in disk detected by sas2ircu (disk removed ?)
Warning : Got the disk /dev/rdsk/c3t1d0 from zpool status, but can't find it in disk detected by sas2ircu (disk removed ?)

disks

List all the disks, along with their associated slot, model, capacity, state, pool, and usage.

The format for the slot is <ctrl>:<enclosureid>:<drivenumber>.

Example:

ledon & ledoff

You can turn on and off the error LEDs of individual drives.

Examples:

Diskmap - berilia> ledon c1t50014EE6ABEA298Fd0
Turning leds on :   1/1
Diskmap - berilia> ledon 1:02:16
Turning leds on :   1/1
Diskmap - berilia> ledoff all
Turning leds on :   36/36

Various input format are supported; use completion to see them all.

enclosures

List detected enclosures on your system. The main purpose is to give you the enclosures ID and define aliases.

Example:

Diskmap - berilia> enclosures
{'50030480:0070d090': {'controller': 1L,
		       'id': '50030480:0070d090',
		       'index': 1L,
		       'numslot': 8L},
 '50030480:0070d320': {'controller': 0L,
		       'id': '50030480:0070d320',
		       'index': 1L,
		       'numslot': 8L},
 '50030480:0075e67f': {'controller': 0L,
		       'id': '50030480:0075e67f',
		       'index': 2L,
		       'numslot': 13L},
 '50030480:009f8c7f': {'controller': 1L,
		       'id': '50030480:009f8c7f',
		       'index': 2L,
		       'numslot': 25L}}

alias

Give an alias to an enclosure. You need the enclosure ID as shown by enclosures.

Examples:

Diskmap - berilia> alias 50030480:0075e67f BCK
Diskmap - berilia> alias 50030480:009f8c7f FNT
Diskmap - berilia> alias
{'50030480:0075e67f': 'BCK', '50030480:009f8c7f': 'FNT'}

enumerate

Helper to generate zpool create command line.

Examples:

STDIN mangling

The program can also be used in a pipe, to enhance the standard output of another program to add device locations to the output of the program.

Example (assuming the aliases defined above):

Know Limitation

At the day of writing, sas2ircu refuse to list your devices if you have more than 256 devices.

Multipath of enclosure sometime have multiple sas address. It should be easy to fix, but I didn't found any document which explain why it change and how much it can change, so right now diskmap don't handle it.
