HPUX script

I would like to run a script to check the dual path of each and every server from a central server. Our storage i using EMC powerpath and our servers are combination of HPUX and Linux. Please ssend me a script to check the path before and after we replace one SAN switch
at a time. Thanks

Create a file "serverlist" containing the network name or IP address of each of your servers, one per line, then run

while read server; do
echo "------ $server ------"
ssh -n $server powermt display paths
done < serverlist

Check the "I/O Paths" column values for "Total" and "Dead"

Please note that you must have ssh access to each of the servers in "serverlist".

How can I filter this into meaningful output that show only the output from the symmetrix logical device . Can you help me filter the output. I dont want to see the other decommissioned storage frames such as Clarion, Hitachi,invista, hp xp, ESS

Here is the script

#!/usr/bin/sh
while read server
do
echo ======= $server =================
ssh -n root@$server "/sbin/powermt display paths"
if [ $? -ne 0 ]; then
echo "[ FAIL ]"
else
echo "[ done ]"
fi
done < hosts_dp_dev

======= server1.dev.na.lafarge.com =================

The above script is very good when the server had the powermt installed. How about if the server is using the native redundancy such as below:
root@server.prd # ioscan -m dsf

This is the output of the script.
How can I identify the redundant path

/dev/rdisk/disk1_p2 1
/dev/rdisk/disk1_p3 1

/dev/rdisk/disk7 1
[ done ]

It's the number in the last column.

Since it's all ones ("1") there are no redundant paths.

From this output, how can I modify the output to give me only the "disk" and not the tapes.
How about the disk with 4 and 6 at the end of the output? What does it mean?
