Storage Account vnet details - azure

Question

I am trying to create a report to find all the storage account and its associated vnet details.
& {
foreach ($storageAccount in Get-AzStorageAccount) {
$storageAccountName = $storageAccount.StorageAccountName
$resourceGroupName = $storageAccount.ResourceGroupName
$context = (Get-AzStorageAccount -StorageAccountName $storageAccountName -ResourceGroupName $resourceGroupName).NetworkRuleSet.VirtualNetworkRules.VirtualNetworkResourceId
$splitarray = $context.Split('/')
$vnetid = $splitarray[8]
$subscriptionid = $splitarray[2]
New-Object psobject -Property #{
Name = $storageAccountName;
Context = $vnetid;
ResourceGroupName = $resourceGroupName
Subscriptionid = $subscriptionid
}
}
} | Format-Table Name, Context, subscriptionid, ResourceGroupName
I am currently getting the below output:
storage account vnet report
As you can see from the output the vnet name is not properly fetched for the storage accounts.
Storage account testfnapp2oct16 has vnet testfnvnet attached, this is correct.
Storage accounts unz2versvaultea, cs1f7b27d61e31e, win10guestdiag954 doesn't have any vnet attached but 'testfnvnet' is repeated until the value changes for a different storage account.
Storage account testfnapp9eb7 has two vnets but only testvnet1 is shown and the value 'testvnet1' is repeated for next storage account.
Any help is much appreciated.

Answer 1

I tried to reproduce the same in my environment it's work me successfully.
I have created sample storage account fetched with vnet and without attached with vnet when I tried, your code I got the same error as below.
To resolve this issue Please utilise the condition I have changed in the code below to execute this issue's solution properly.
& {
foreach ($storageAccount in Get-AzStorageAccount) {
$storageAccountName = $storageAccount.StorageAccountName
$resourceGroupName = $storageAccount.ResourceGroupName
$context = (Get-AzStorageAccount -StorageAccountName $storageAccountName -ResourceGroupName $resourceGroupName).NetworkRuleSet.VirtualNetworkRules.VirtualNetworkResourceId
$ErrorActionPreference = ‘SilentlyContinue’
if ($context -eq $null){
New-Object psobject -Property #{
Name = $storageAccountName;
Context = "Empty" ;
ResourceGroupName = $resourceGroupName
Subscriptionid = $subscriptionid
}
}
else {
$splitarray = $context.Split('/')
$vnetid = $splitarray[8]
$subscriptionid = $splitarray[2]
New-Object psobject -Property #{
Name = $storageAccountName;
Context = $vnetid;
ResourceGroupName = $resourceGroupName
Subscriptionid = $subscriptionid
}
}
}
} | Format-Table Name, Context, subscriptionid, ResourceGroupName
Result:
Now, whichever vnet are not fetched in my storage account it's show Empty like below.
