Compellent Statisics and statuses using PowerShell

Hello

I hope this thread is stil lalive and people are reading it

I was asked to create a simple Compellent status report and, actually, it's PowerShell is very good. Except...I can't figure out why I can't "refresh" data I get.

So, I am using Get-DellScDiskClassStorageUsage cmdlet. During the process of writing the script everything worked well. Now there were some changes (we deleted some volumes) I see that DSM's data refreshed, but PowerShell output remains the same.

 

Here is the code I was using for it:

 

# Import DellEMC PowerShell module
Import-Module C:\Windows\System32\WindowsPowerShell\v1.0\Modules\DellStoragePowerShellSDK-5.2.0.4\DellStorage.ApiCommandSet.psd1

# Check connection. If state is NOT Connected - connect to the server
$password = ConvertTo-SecureString "password" -AsPlainText -Force
$conn = Connect-DellApiConnection -HostName myDSMserver.com -User "viewer" -Password $password

$compellents = Get-DellScConfiguration -Connection $conn

.....

$array_disks_sizes = @()
foreach ($compellent in $compellents)
{

$info7K = Get-DellScDiskClassStorageUsage -Instance "$($compellent.ScSerialNumber).4" -Connection $conn 
[math]::Round($info7K.TotalSpace.ByteSize /1TB, 2) #Total Space
[math]::Round($info7K.AllocatedSpace.ByteSize /1TB, 2) #Allocated Space
[math]::Round($info7K.SpareSpace.ByteSize /1TB, 2)
[math]::Round($info7K.FreeSpace.ByteSize /1TB, 2)
$free_percent_HDD = [math]::Round($info7K.FreeSpace.ByteSize / $info7K.TotalSpace.ByteSize * 100, 2)
$infoSSD = Get-DellScDiskClassStorageUsage -Instance "$($compellent.ScSerialNumber).10" -Connection $conn
[math]::Round($infoSSD.TotalSpace.ByteSize /1TB, 2) #Total Space
[math]::Round($infoSSD.AllocatedSpace.ByteSize /1TB, 2) #Allocated Space
[math]::Round($infoSSD.SpareSpace.ByteSize /1TB, 2)
[math]::Round($infoSSD.FreeSpace.ByteSize /1TB, 2)
$free_percent_SSD = [math]::Round($infoSSD.FreeSpace.ByteSize / $infoSSD.TotalSpace.ByteSize * 100, 2)
