Checking EMC Networker configuration on new Windows Server builds

Background

You have been tasked to find out if EMC Networker is configured properly on your new Windows Server builds. This could be achieved by running an Ansible Playbook coupled with a PowerShell script.

Script

Playbook

#Define list of servers and their respective login details, this could be achieved differently depending on your infrastructure design

- name: capture servers list

hosts: localhost

vars:

- servers: "{{ myhost.split(',') }}"

gather_facts: false

- name: Check backup configuration

script: backservercheck.ps1

register: backupserver

failed_when: "'Backup client configured properly' not in backupserver.stdout"

ignore_errors: true

PowerShell

In this example, we wanted to check the backup configuration on 2 sites where each site had their own Backup servers. Hence, this script taps on the naming convention of each Windows Server to determine which Backup server it should connect to.

$hostname = $env:COMPUTERNAME

if ($hostname -like '*naming convention 1*') {

$backserverlist = @('backup server 1 - site 1','backup server 2 - site 1')

foreach ($bckupserver in $backserverlist) {

 #Define nsr command

        $command = "echo print type: nsr client; name: $hostname | nsradmin -s $bckupserver -p nsrd"

 #Run nsr command in cmd

        $output = cmd.exe /c $command

if($output -like '*scheduled backup: Enabled*') {

Write-Host "Backup client configured properly"

break

}

}

} elseif ($hostname -like '*naming convention 2*') {

$backserverlist = @('backup server 1 - site 2','backup server 2 - site 2')

foreach ($bckupserver in $backserverlist) {

$command = "echo print type: nsr client; name: $hostname | nsradmin -s $bckupserver -p nsrd"

$output = cmd.exe /c $command

if($output -like '*scheduled backup: Enabled*') {

Write-Host "Backup client configured properly"

break

}

}

}

Powershell script for checking Windows Server cluster health

Background

You have been tasked to write a script to check the health of your Windows Server clusters. Additionally, you are also required to email the cluster health report to your team.

Script

In order for the following script to work, FailoverClusters module must be imported to the sever that this script will run on. This can be achived by running the following command and it is a one-time task.

Import-Module FailoverClusters

param(

#parameter 1, cluster server list

[String]$clustersfile,

#parameter 2, email the report or not. Default is Yes.

[String]$emailtoteam="Yes"

)

#start of summary text

$summary = "############## Summary ##############`r`n"

#define log file

$logfile = "path to log file_$(get-date -f yyyyMMddhhmmss).txt"

$clusterlist = get-content $clustersfile

foreach ($cluster in $clusterlist) {

$errorflag = 0

Write-Host $cluster

$summary += $cluster

$cluster | Out-File $logfile -Append

if(Get-Cluster -Name $cluster -ErrorAction Continue) {

### cluster node

$clusternodes = Get-ClusterNode -Cluster $cluster

$clusternodes | ft | Out-File $logfile -Append

foreach ($clusternode in $clusternodes) {

if(($clusternode | select -ExpandProperty State) -ne "Up") {

$errorflag += 1 #if the status is not UP, then report error

}

}

### cluster resource

$clusterresources = Get-ClusterResource -Cluster $cluster

$clusterresources | ft | Out-File $logfile -Append

foreach ($clusterresource in $clusterresources) {

if(($clusterresource | select -ExpandProperty State) -ne "Online") {

$errorflag += 1 #if the status is not ONLINE, then report error

}

}

if($errorflag -ne 0) {

"ERROR: Check cluster`r`n" | Out-File $logfile -Append

Write-Host "Check cluster" -BackgroundColor Red -ForegroundColor White

Write-Host ""

$summary += " : Check cluster`r`n"

} else {

"OK`r`n" | Out-File $logfile -Append

Write-Host "OK" -BackgroundColor Green -ForegroundColor Black

Write-Host ""

$summary += " : OK`r`n"

}

"----------------------------------------------`r`n" | Out-File $logfile -Append

} else {

"`r`nERROR: Cannot connect to cluster, Please check manually`r`n" | Out-File $logfile -Append

"----------------------------------------------`r`n" | Out-File $logfile -Append

Write-Host "Cannot connect to cluster, Please check manually" -BackgroundColor Red -ForegroundColor White

Write-Host ""

$summary += " : Cannot connect to cluster, Please check manually`r`n"

Continue

}

}

$summary | Out-File $logfile -Append
