ESXcli 命令超时 30 分钟

Question

我正在编写一个 powercli 脚本，用于循环遍历我们环境中的每个数据存储并回收精简配置 LUN 上的空间。环境中的所有 LUN 都是 Dell Equal Logic。

vCenter 版本：5.5.0_1750787

ESXi 版本：Dell 5.5-1331820(A01)

我遇到的问题是，在脚本中执行取消映射命令后正好 30 分钟，出现以下错误：

从 PowerCLI：

Message:  An error occurred while communicating with the remote host:

我无法找到可以在脚本中调整的 30 分钟会话超时。我尝试在 PowerCLI 中删除或增加 Web 会话超时，但没有成功：

Set-PowerCLIConfiguration -WebOperationTimeoutSeconds -1 -Scope Session -Confirm:$false
Set-PowerCLIConfiguration -WebOperationTimeoutSeconds 3600 -Scope Session -Confirm:$false

关于改进以下脚本的任何指导或建议都将非常有帮助：

## 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

Answer 1

您提到：

我无法找到可以在脚本中调整的 30 分钟会话超时。我尝试在 PowerCLI 中删除或增加 Web 会话超时，但没有成功：>

请尝试此操作，因为它看起来像是 vCenter 主机本身的超时。

vpxd.cfg 文件

要配置超时和最大会话数：

使用文本编辑器打开 vpxd.cfg 文件。

vpxd.cfg 文件位于：Windows XP：C:\Documents and Settings\All Users\Application Data\VMware\VMware VirtualCenter\vpxd.cfg Windows Server 2003：C:\Documents and Settings\All Users\Application Data\VMware\VMware VirtualCenter\vpxd.cfg Windows Server 2008：C:\ProgramData\VMware\VMware VirtualCenter\vpxd.cfg

在文件中找到标签。设置 maxSessionCount 和 sessionTimeout 参数。

例如：

... 500 30

注意：会话超时值以分钟为单位指定。在 vCenter Server 2.5.x 中，默认值为 30 分钟和 100 个会话。进行此更改后，您可能还需要重新启动 VMware VirtualCenter Server 服务。

• vCenter Server 日志报告错误：已达到 SOAP 会话计数限制 (2004663)

Answer 2

尝试这个

Set-PowerCLIConfiguration -Scope Session -WebOperationTimeoutSeconds -1

信用

Answer 3

我也遇到了同样的问题。按照本帖前面提到的方法先设置超时。

Set-PowerCLIConfiguration -WebOperationTimeoutSeconds -1

然后如果可能的话直接连接到主机。

$h = Connect-VIServer "hostname"

$ESXCLI = Get-EsxCli -VMHost "hostname" -server $h

这对我来说是有效的。就我而言，似乎是 vCenter 超时了，而不是我的 powercli。
