Edit: I still love handy scripts.

IBMer Glenn Lehman posted this script on a mailing list, and with his permission I’m posting it here. Glenn offered this introduction and description: “I search for various 4-digit IBM storage types. My example is coded to recognize 2810, 2107,1750 (which translates to XIV, DS8300, DS6800).
“I share this as an intro… because prior to starting, our team was concerned with how we would keep track of all this configuration information, so I wrote and we now use my handy script. It gathers and parses and organizes all the info we wanted to track into neat columns. It’s all automatic, and all real-time.
“Our environment was all p570 frames — and strictly NPIV (no vSCSI). We have dual SAN fabrics and dual VIO servers per frame for redundancy and disk multi-pathing.
“Let me know if you find this useful, or if you make any changes or modifications so we can share it with others.”
He adds that the following should be customizable for those familiar with ksh scripting.

#@============================================================================
# Script : Collect and display FC/Disk/SAN info for given VIOS pair
# Author : Glenn Lehman / IBM
#
# History : Created: Thu Jan 26 EST 2012
# Modify : Jan 30 2012 – add dph VIOS option
# : Jan 31 2012 – add ping test to confirm VIOS is active
# : Feb 06 2012 – add uniq date suffix to TMP filename
# : Feb 09 2012 – add disk type and count to output
#
# Usage : Invoke from remote LPAR with NPIV frame parameter
#=============================================================================
#
########################## Assumptions ################################
# There is a remote server that can access all VIO-servers & VIO -clients
# and that remote server is where this script resides and invokes from
# There are 2 VIO-Servers in a given frame
# There is a distributive shell method configured in the environment
# The LPAR profile name is VIO-…
# Example: Profile=> VIO-hostAix61prd
# Hostname=> hostAix61prd
# Storage types are one of the following:
# XIV – 2810
# DS8300 – 2107
# DS6800 – 1750
# There are dual SAN Fabrics with unique domains, so that the FCIDs
# can pinpoint the fabric
# Example:
# 0x15 Fabric vs. 0x16 Fabric
########################## Customization Step #########################
# Assign the distributive shell command and usage options
