NetApp disk model and firmware reporting

Some times you want a quick report of the disk types and firmware versions with the number of disks on each version.

Recently NetApp put out a billiton about older disk firmware failing more often that they should. I was given the task of making sure all our disks where OK. To archive that I had to update a lot of disks. The process is straight forward and I may do a post about that. But once you have uploaded the necessary firmwares you may need to keep track of the progress.

So here is a quick script i made in to a function

It basically gets an array of all the disks

gets all the disks in to an array
creates a array of all unique disk models
loops through the disk model array and gets firmware versions in to another array
now loops through the firmware array getting the number of disks at that version

so you end up with something this

Disk model 100, firmware 100, disks 5
Disk model 100, firmware 101, disks 2
Disk model 103, firmware 105, disks 10
Disk model 103, firmware 106, disks 50

Using this I can quickly see what model disks are on what version of firmware. I run it after the I uploaded the firmware to track the upgrade process.

So here is the script

import-module posh-ssh

$cred = Get-Credential
$AFF = "MyFAS.lab.local"

$Connection = Connect-NcController $AFF -Cred $Cred


function Get-NCdiskFirmwares
{
    $Disks = get-ncdisk

    # get a n array of unique disk models
    $diskMods = $Disks.model | sort -Unique

    # loop through each disk model
    foreach ($diskMod in $diskMods)
    {
        # get an array of disk of the current model
        $FWversionDisks = $Disks | where{$_.model -eq $diskMod}

        # get an array of all the unique firmware versions
        $FWVersions = $FWversionDisks.FW | sort -Unique

        # loop though each firmware version
        foreach ($FWVersion in $FWVersions)
        {
            # get an array of the current model and current firmware version and count the number of disks, print it to the screen
            $NumDisks = ($Disks | where{$*.model -eq $diskMod -and $*.FW -eq $FWVersion}).count
            "disks, model " + $diskMod + " , FW  " + $FWVersion + " , number " + $NumDisks
        }
    }
}

now run the function and you will get a list of the number of disks at a specific model and firmware version.

Get-NCdiskFirmwares

disks, model X4002S172A3T8NTE , FW NA02 , number 22
disks, model X4002S172A3T8NTE , FW NA03 , number 14
disks, model X4011S172B3T8NTE , FW NA54 , number 24
disks, model X4011S17333T8NTE , FW NA50 , number 47
disks, model X4011S17333T8NTE , FW NA51 , number 15
disks, model X4016S172B3T8NTE , FW NA54 , number 12
