如何使用PowerCLI获取物理RDM LUN的路径选择策略

获取RDM磁盘信息是一件很磨人的事儿,如果你很仔细你就需要把每台都检查一遍以确保信息是一致的。研究出来两行命令,可以批量获取RDM磁盘信息。



[do_widget "Language Switcher" wrap=aside title=false]

$VM  = Get-hardDisk -VM [VM name] -DiskType RawPhysical

$VM | select ScsiCanonicalName | foreach {Get-Cluster -Name [Cluster name] | Get-VMHost | Get-ScsiLun -CanonicalName
$_.ScsiCanonicalName} | select CanonicalName,CapacityGB,MultipathPolicy,VMHost | Format-Table -AutoSize


运行前别忘了把[VM name] & [Cluster name]替换成你自己的值!

这个命令会返回RDM LUN的PSP、LUN NAA、ESXi主机名。ESXi 5.5对于物理RDM LUN的支持变成“Round Robin”模式了,升级ESXi后你需要变更一下PSP,可以看看我的文章如何使用vCLI获取或设定路径选择策略了解如何批量变更PSP。

Connect-NsxtServer shows "Unable to connect to the remote server"

When you run Connect-NsxtServer in the PowerCLI, it may show "Unable to connect to the remote server".  Because the error message is a little bit confusing with other login issues. It's not easy to troubleshoot. The actual reason is the NSX-T uses a self-signed certificate, and the PowerCLI cannot accept the certificate automatically. The fix is super easy. You need to set the PowerCLI to ignore the invalid certificate with the following command: Set-PowerCLIConfiguration -Scope User -InvalidCertificateAction:Ignore -Confirm:$false

Setup Terraform and Ansible for Windows provisionon CentOS

Provisioning Windows machines with Terraform is easy. Configuring Windows machines with Ansible is also not complex. However, it's a little bit challenging to combine them. The following steps are some ideas about handling a Windows machine from provisioning to post configuration without modifying the winrm configuration on the guest operating system. Install required repos for yum. yum -y install https://repo.ius.io/ius-release-el7.rpm yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm yum -y install https://packages.endpointdev.com/rhel/7/os/x86_64/endpoint-repo.x86_64.rpm yum -y install epel-release yum -y install yum-utils yum-config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo Install  Terraform . sudo yum -y install terraform Install  Ansible . sudo yum -y install ansible Install  Kerberos . yum -y install gcc python-devel krb5-devel krb5-libs krb5-workstation

How to List All Users in Terraform Cloud

Terraform has a rich API. However, the API documentation does not mention how to list all users. We can leverage the organization membership API and the PowerShell command  Invoke-RestMethod  to get a user list. 1. Create an organization token in Terraform Cloud. 2. Create the token variable ( $Token ) in PowerShell. $Token = "abcde" 3. Create the API parameters variable in PowerShell. $params = @{ Uri = "https://app.terraform.io/api/v2/organizations/ZHENGWU/organization-memberships?page%5Bsize%5D=100" Authentication = "Bearer" Token = $Token ContentType = "application/vnd.api+json" } Note: You need to replace ZHENGWU with your own organization name. And I used 100 at the end of the URI to retrieve the first 100 users. It can be any number.  4. Retrieve the API return and list the user's email address. $Test = Invoke-RestMethod @params $Test.data.attributes.email
