Mapping OS Devices to Veritas Device names in Veritas 5.1

With Veritas 5.1, if you are using native DMP, enclosure based naming is mandatory.

Now this is good as 5.1 has enhancements where the device name now includes the LDEV number for the array and it makes it easy for storage grows.

But this can kind of be a PITA if you are building fresh or you don’t have the LDEV number and are just trying to find the veritas device name for a set of luns.

This is a expansion of a 1 liner I posted awhile back, it has been expanded to include the Veritas Device name in the output.

Here it is and you can copy/paste it into a bash session. You can change the order and padding by modifying the awk statement

for c in $(iostat -En | grep Soft | awk '{print $1}' | cut -d t -f1 | sort | uniq); do 
for i in `iostat -En | grep Soft | awk '{print $1}' | grep "$c"`;do 
vxdisk list $i &>/dev/null || continue
DEV=`vxdisk list $i | grep Device | awk '{print $2}'`
SZ=$(iostat -En $i | grep Size | cut -d'<' -f2)
echo "$i ${SZ%% *} $DEV" | awk '{printf ( "%s\t%s %4d GB (%d MB)\n", $1, $3, $2/1024/1024/1024+.05, $2/1024/1024+.05) }'
done | sort -t d +1 -n; done

This is the output of vxdisk list

Now here is the script with only 2 columns. Since format works on the Unix Devices and vxdisksetup on the Veritas Device name. This script is useful for building a input file for a multivariable read while loop to label and then initialize the disk.

for c in $(iostat -En | grep Soft | awk '{print $1}' | cut -d t -f1 | sort | uniq); do
for i in `iostat -En | grep Soft | awk '{print $1}' | grep "$c"`;do
vxdisk list $i &>/dev/null ||  break
DEV=`vxdisk list $i | grep 'Device:' | awk '{print $2}'`
printf "%s\t%s\n" $i $DEV; done  | sort -t d +1 -n; done
