Je travaille sur un script powercli pour parcourir chaque magasin de données de notre environnement et récupérer de l'espace sur les LUN provisionnés. Tous les LUN de l'environnement sont Dell Equal Logic.
Version de vCenter: 5.5.0_1750787
Version ESXi: Dell 5.5-1331820(A01)
Le problème que je rencontre est qu'exactement 30 minutes après l'exécution de la commande unmap dans le script, j'obtiens les erreurs suivantes:
De PowerCLI:
Message: An error occurred while communicating with the remote host:

Je n'ai pas pu trouver de délai d'expiration de session de 30 minutes que je peux modifier dans le script. J'ai tenté de supprimer ou d'augmenter le délai d'expiration de la session Web dans PowerCLI sans succès:
Set-PowerCLIConfiguration -WebOperationTimeoutSeconds -1 -Scope Session -Confirm:$false
Set-PowerCLIConfiguration -WebOperationTimeoutSeconds 3600 -Scope Session -Confirm:$false
Toute direction ou conseil sur l'amélioration du script suivant serait très utile:

## vmware_unmap_datastore.ps1 #################################################
Usage: powershell -ExecutionPolicy Bypass -File ./vmware_unmap_datastore.ps1
Purpose: Dumps Datastore (in GB): Capacity, Free, and Uncommitted space to
to CSV and runs ESXCli command 'unmap' to retrieve unused space
on Thin Provisioned LUNs.
Requirements: Windows Powershell and VI Toolkit
Assumptions: All ESXi hosts have access to all datastores
TO DO: Import Dell Equal Logic Module, get Used space before/after unmap
