Tôi đang làm việc trên một tập lệnh powercli để lặp qua từng kho dữ liệu trong môi trường của chúng tôi và lấy lại không gian trên các LUN được cung cấp mỏng. Tất cả các LUN trong môi trường là Dell Equal Logic.
phiên bản vCenter: 5.5.0_1750787
Phiên bản ESXi: Dell 5.5-1331820(A01)
Vấn đề tôi gặp phải là chính xác là 30 phút sau khi thực hiện lệnh unmap trong tập lệnh, tôi gặp (các) lỗi sau:
Từ PowerCLI:
Message: An error occurred while communicating with the remote host:

Tôi đã không thể tìm thấy thời gian chờ phiên 30 phút mà tôi có thể điều chỉnh trong tập lệnh. Tôi đã cố gắng loại bỏ hoặc tăng thời gian chờ phiên Web trong PowerCLI nhưng không thành công:
Set-PowerCLIConfiguration -WebOperationTimeoutSeconds -1 -Scope Session -Confirm:$false
Set-PowerCLIConfiguration -WebOperationTimeoutSeconds 3600 -Scope Session -Confirm:$false
Bất kỳ hướng hoặc lời khuyên nào về việc cải thiện tập lệnh sau đây sẽ rất hữu ích:

## vmware_unmap_datastore.ps1 #################################################
Usage: powershell -ExecutionPolicy Bypass -File ./vmware_unmap_datastore.ps1
Purpose: Dumps Datastore (in GB): Capacity, Free, and Uncommitted space to

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
