One of my customers was doing some work on their storage network and so wanted a list of all ESXi hosts and their WWNs.  This struck me as another excellent scripting opportunity, so I pulled out my old Brocade 1:1 Zoning script and went to work.  I really only needed a one-liner for this situation, so I extracted my needed syntax from that script and quickly put it together.  Here's the (admittedly, ugly) command that I came up with: get-vmhost | select name,@{N="WWNs";E={($_.ExtensionData.config.storagedevice.hostbusadapter.PortWorldWideName | % {("{0:X}"-f$_ -split '(..)' | ? {$_}) -join ':'}) -join ", "}} That'll spit out a list with two columns, ESXi host names in one, and a comma separated list of WWNs in the other.  So, what's that ugly expression in that select statement doing?  Well, it's collecting all of the port WWNs on that ESXi host, then converting each one from decimal into hexadecimal (the "{0:X}...

A while back, I posted a quick script to create commands for  1:1 Zoning on a Brocade Fiber Switch .  I was recently helping someone go through that exact process on a set of switches that had a lot of aliases already defined on them.  Their challenge was that they weren't sure which aliases were for their current SAN vs. a retired SAN.  Rather than just creating zones for both SANs, I decided to put together a quick script that would scrape their current Aliases and check which ones have active WWNs currently in the system.  They could then use this information to prune the Aliases that are no longer needed, in addition to only creating the required zones for our project. In order to do this task, I had to do some quick string parsing into PowerShell objects .  Good thing I already know how to do that ;)  So, I put together this script which does two things: 1) It parses the Brocade Fiber Switch's configuration to look for any Aliases 2) It checks...
