Get the netapp cluster mode count and the total sizeper disks type

[tchuise92]

Good afternoon,

I am new in powershell and i want to know if someone could help me collecting the count of disks and also the total usable space per each disks type.

$AllDisks7M += $NonMetroDisks7M
$AllDisks7M += $MetroDisks7M
$AllDisks7M += $ReplicationDisks7M
ForEach($Disk7M in $AllDisks7M)
{
$foundType = 0
for($i = 0; $i -le $DiskTypes7M.Length-1; $i++)
{
if($DiskTypes7M[$i][0] -eq $Disk7M.PhysSpace)
{
$DiskTypes7M[$i][1] ++
$foundType = 1
}
}
if(!$foundType)
{
$DiskTypes7M += ,@($Disk7M.PhysSpace, 1)
}
}
$DiskTypes7M = $DiskTypes7M | sort-object @{Expression={$_[0]}; Ascending=$false}

I used that script for collecting on 7 mode but it is not working on cluster mode prompting this message:

You cannot call a method on a null-valued expression.
At line:103 char:1
+ $p.TotalSize = $PDCTSizeCM.toString()

What is the expected output of your script?

[tchuise92]

 this for example is the output of the 7 mode

PS C:\Users\XXXX> $DiskTypes7M

4000787030016

200

1778132385792

231

588124522352

701

587421531156

305

293710764580

216

288196759322

457

I want to have this type of matrix for the cluster mode as well

for example for the first 2 lines

the longer number is the total size of the 200 disks type X306-XXXXXXXX of my system

Interesting..

start with get-ncdisk

And to convert the numbers use convertto-formattednumber cmdlet

[tchuise92]

When I use this command it show the size of the different disks not the total size like I was thinking

ConvertTo-FormattedNumber 4000787030016

ConvertTo-FormattedNumber 4000787030016

ConvertTo-FormattedNumber 1778132385792

ConvertTo-FormattedNumber 588124721152

ConvertTo-FormattedNumber 587421536256

ConvertTo-FormattedNumber 293710766080

ConvertTo-FormattedNumber 288196759552
4T
4T
2T
588G
587G
294G
288G

Here's what I came up with...you'll want to adjust depending on what you want to see.

$diskReport = @{}

Get-NcDisk | %{
    $diskCapacity = ConvertTo-FormattedNumber ($_.DiskInventoryInfo.BytesPerSector * $_.DiskInventoryInfo.RightSizeSectors)
    $id = "$($_.DiskInventoryInfo.DiskType)_$($diskCapacity)"

    if ($diskReport.Keys -notcontains $id) {
        $diskReport.$($id) = @{ 'Capacity' = 0; 'Count' = 0; }
    }
    
    $diskReport.$($id).Capacity += $_.Capacity
    $diskReport.$($id).Count++
        
}

$diskReport.GetEnumerator() | Select @{'N'="DiskType";'E'={ $_.Name }}, @{'N'="TotalRawCapacity";'E'={ ConvertTo-FormattedNumber $_.Value.Capacity }},@{'N'="Count";'E'={ ConvertTo-FormattedNumber $_.Value.Count }}

This will show the disk type (SAS, SSD, SATA) and the right size value as a single field, e.g. "SAS_1T", along with the total raw capacity of the disk type in the system and the count.

DiskType TotalRawCapacity Count
-------- ---------------- -----
SAS_445G 43T              96   
SAS_1T   49T              40   
SSD_406G 3T               8

This is great thanks! How can this be iterated for many filers?  tx.

If you want to use disk model for the "type" information that's an easy modification from what I had originally...

$diskReport = @{}

Get-NcDisk | %{
    $id = $_.DiskInventoryInfo.Model

    if ($diskReport.Keys -notcontains $id) {
        $diskReport.$($id) = @{ 'Capacity' = 0; 'Count' = 0; }
    }
    
    $diskReport.$($id).Capacity += ($_.DiskInventoryInfo.BytesPerSector * $_.DiskInventoryInfo.RightSizeSectors)
    $diskReport.$($id).Count++
        
}

$diskReport.GetEnumerator() | Select `
    @{'N'="DiskType";'E'={ $_.Name }}, `
    @{'N'="TotalRawCapacity";'E'={ ConvertTo-FormattedNumber $_.Value.Capacity DataSize "0.00" }}, `
    @{'N'="Count";'E'={ ConvertTo-FormattedNumber $_.Value.Count }}

Which results in:

DiskType         TotalRawCapacity Count
--------         ---------------- -----
X438_1625400MCSG 2.95 TB          8    
X425_HCBEP1T2A10 44.26 TB         40   
X421_FAL12450A10 38.46 TB         95   
X421_HCOBD450A10 414.58 GB        1    

Note I changed Convertto-FormattedNumber to use more precision in the output also.

Thank you a lot Andrews, I have been off work for a while that helps me a lot.I will test it in my environment
