Description
This procedure shows how to recreate lun mapping from a show configuration or a show lun map file on a Sun StorEdge[TM]3000 array after a failed upgrade (for example) or a reset to factory default


Steps to Follow
This document explains how to recreate mapping for a Sun StorEdge[TM]3000 array after controllers were reset to factory defaults (for example, after a failed upgrade of controller firmware)

Pre-requisite:
--------------

  • Installed sccli release ( SUNWsscs installed pkg should be compliant with the used Sun StorEdge[TM]3000 array). You can find SUNWsscs package at the following URL : http://www.sun.com/download -> Storage Management -> Sun StorEdge [tm] 3000 Family Storage Products--Related Software
  • A previous and correct show configuration output containing lun mapping informations ( or a show_lun-map from se3kxtr or explorer)
  • having targets settings for the used host channels
  • IP address of the Sun StorEdge[TM]3000 array is set
  • no remainder of a previous lun mapping to avoid duplication mapping

1)After having set the correct targets for all used host channels, extract the mapping information from show configuration (or show_lun-map) to a file (for example : lun_map.txt)

It should look like this (after removing the header) :

#cat /<path_to_file>/lun_map.txt
0 33 0 ld1 4B21FCF5-00 Secondary 210100E08B3D7B7B
0 33 0 ld1 4B21FCF5-00 Secondary 210100E08B3DDD7E
0 33 1 ld1 4B21FCF5-01 Secondary 210100E08B3D7B7B
(...)

2) Here is a script to (re-)create lun mapping as the original one

% more script_mapping
#! /bin/sh

while read LINE
do
set $LINE
PARTITION=$5
CHANNEL=$1
TARGET=$2
LUN=$3
WWPN=$7
sccli <device> map $PARTITION $CHANNEL.$TARGET.$LUN $WWPN
done

or a shorter one

% more script_mapping (compact)
#! /bin/sh

while read LINE
do
set $LINE
sccli <device> map $5 $1.$2.$3 $7
done

<device> is the IP address of the array or the appropriate /dev/rdsk/cXtYdZs2 listed after executing sccli command with no argument

3)Use the script:

#./script_mapping < /<path_to_file>/lun_map.txt

Notice :
--------
. make sure the script is executable
. Field WWPN for lun filtering is optional (depending on customer's configuration) (See help map in sccli> )
