Issue on Multipathing Script

dinu03 · 2022-01-23T10:29:50.000Z

Hi

“hostname” | % { write-host $_ -ForegroundColor green ; (gwmi -ComputerName $_ -Namespace root\wmi -Class mpio_disk_info).driveinfo | Select-Object {“Name: $($.name) Paths: $($.numberpaths)”}}

Instead of below output:

hostname
“Name: $($.name) Paths: $($.numberpaths)”

Name: MPIO Disk0 Paths: 2
Name: MPIO Disk1 Paths: 2
Name: MPIO Disk2 Paths: 2
Name: MPIO Disk3 Paths: 2
Name: MPIO Disk4 Paths: 2

I want ouptut as below:

Name Paths

MPIO Disk0 2
MPIO Disk1 2
MPIO Disk2 2
MPIO Disk3 2
MPIO Disk4 2

Create a PSCustomObject and you can easily format it the way you want.

You can use calculated properties with your Select-Object:

Select-Object @{n='Name';e={$_.Name}},@{n='Paths';e={$_.NumberPaths}}

Just about every post you post, I ask you to please use the insert code button and you keep ignoring it…

If you post code, please use the ‘Insert Code’ button. Please and thank you!

PLEASE READ BEFORE POSTING! Read if you're new to the PowerShell forum! Programming & Development

Hi, and welcome to the PowerShell forum! Don’t apologize for being a “noob” or “newbie” or “n00b.” There’s just no need – nobody will think you’re stupid, and the forums are all about asking questions. Just ask! Use a descriptive subject. Don't say "Need help" or "PowerShell Help", actually summarize what the problem is. It helps the rest of us keep track of which problem is which. Don’t post massive scripts. We’re all volunteers and we don’t have time to read all that, nor will we copy, past…

In general PLEASE FOLLOW POWERSHELL BEST PRACTISE.

You are using an alias ( % ), rather than ‘foreach-object’
powershell does not need a ( ; ) at the end of the line
your calculated property syntax is wrong
you should use ‘cim’ rather than WMI as much as you can

e.g.

$hostnames = "hostname"

foreach($host in $hostnames){
    $driveInfo = (Get-CimInstance -ComputerName $host -Namespace root\wmi -Class mpio_disk_info).driveinfo
    foreach($drive in $driveinfo){
        [pscustomobject]@{
            HostName  = $host
            DriveName = $drive.name
            DrivePath = $drive.path
        }
    }
 }

please adhere to standards. sure it works if you don’t follow them, but man it makes troubleshooting and asking for help much easier and the next person who is going to have to read your code will be thankful as well.

Maybe the OP is using a mobile phone to post.
The insert doesn’t work from an iPhone.
At least I haven’t found the way.
You have to know the syntax and write your own HTML.
I emailed myself the syntax, so I know how but I doubt 1/1000, if that many, do.

From a mobile phone you can do (I know I’m going to screw this up but let’s see……): From a mobile device, post formatted PowerShell using:


< pre class="syntax powershell" >

  Code goes here….   

< /pre>

Let’s test this:


[Array]$things=“Red”, “White”, “Blue”

foreach ($thing in $things) {

    write-host $thing

}

BTW, the illustration 2 posts above showing the syntax necessary to format a post as PowerShell is nested in an HTML Syntax block
