Well, today I had another idea (basically like the one I wrote for SVC’s VDisk mappings a while back) for a script:

; html-script: false ]#!/bin/bash KEY_FILE="/root/.ssh/netapp.dsa" SSH_OPTS="/root/.ssh/netapp-ssh_config" if [ $# -ne 3 ] ; then echo "fas-copy-lunmap: FAS_CONTROLLER SOURCE_IGROUP TARGET_IGROUP" echo echo "Copy the LUN map from one igroup to another, ie for ESX reinstallation" echo echo " Usage:" echo " - FAS_CONTROLLER: Hostname/IP-adress of the DATA ONTAP controller" echo " - SOURCE_IGROUP: igroup that is used as a reference for the copy process" echo " - TARGET_IGROUP: igroup that is actually modified" echo exit 1 fi FAS_CTRL=$1 SOURCE=$2 TARGET=$3 ssh_fas() { # $@: commands for Data ONTAP COMMANDS="$@" /usr/bin/ssh -i $KEY_FILE -l root -F $SSH_OPTS $COMMANDS } #set -x # Get the lun list. for lun in $( ssh_fas $FAS_CTRL lun show -g $SOURCE | awk '{ print $1 }' | sort -u ); do # Get the LUN number its mapped LUN_ID="$( ssh_fas $FAS_CTRL lun show -m $lun | grep "^/vol" | awk '{ print $3 }' )" # If the LUN id is 0, skip otherwise we would copy the boot LUN if [ "$LUN_ID" != "0" ] ; then # Actually map the lun to our host echo "Mapping $lun to $TARGET as LUN_ID $LUN_ID" ssh_fas $FAS_CTRL lun map $lun $TARGET $LUN_ID fi done #set +x |
I’ll post the counterpart of the script (to remove the LUNs) in a second post later on.
