LUN Comparison Report

[uswbnc53]

Luc has this great script to create a report of disks being used, in my case I need to map duplicate RDMs mapped to virtual machines across hosts, and I'm having issues getting it to run. My hosts, virtual machines, clusters all have "-" in them.

Anybody have experience with getting this to work? Your help is greatly appreciated!

http://www.lucd.info/2010/04/09/lun-report-datastores-rdms-and-node-visibility/

I have tried to add the line
$LunInfoDef += (“`n`tpublic string ” + ($_.Name.Split(“.”)[0].Replace('-','')) + ";")

And attempted to modify all lines with "-".

Example:
Hostname: okc-clu-esx01
VM: okc-clu-vm01

Cluster: okc-cluster1

I'm getting these errors, plus the others mentioned in the post referenced.

Cannot index into a null array.
At C:\users\nulluser\desktop\LUN.ps1:40 char:36
+             $scsiTab[$key] = $scsiTab[$key][ <<<< 0], $dsName, $scsiTab[$key][2]
    + CategoryInfo          : InvalidOperation: (0:Int32) [], RuntimeException
    + FullyQualifiedErrorId : NullArray

Yes, that is a known problem.

Unfortunately the sript uses the hyphen as a seperator in the key. and the hyphen is also a valid character for VM and Hostnames in vSphere.

You can replace the hyphen in 5 lines with another character to solve the problem.

See also one of my earlier replies on that post.

In any case, in the attached script, the hyphen is replaced by a hash character ('#').

Try that one.

Hey Luc,

I ran the script you sent and I'm still getting the same error. It keeps failing on 40 char:36.

Strange, I'll drop you an email to ask for some details.
