Working with iDRAC9 Redfish API using PowerShell - Part 4


In this article, I will explain how to use iDRAC Redfish API to Power On and Graceful Shutdown a server using PowerShell. This is applicable to all Dell EMC servers having iDRAC. It can be a general-purpose PowerEdge rack server, Ready Node, Appliance, etc. I've tested on iDRAC9.

Note: In a production environment please make sure to follow proper shutdown or reboot procedure (if any) before performing any system reset actions on the server.

[CmdletBinding()]
param(
    [Parameter(Mandatory)]
    [String]$idrac_ip,

    [Parameter(Mandatory)]
    [ValidateSet('On''GracefulShutdown')]
    [String]$ResetType
)

#To fix the connection issues to iDRAC REST API
add-type @"
    using System.Net;
    using System.Security.Cryptography.X509Certificates;
    public class TrustAllCertsPolicy : ICertificatePolicy {
    public bool CheckValidationResult(
        ServicePoint srvPoint, X509Certificate certificate,
        WebRequest request, int certificateProblem) {
        return true;
        }
    }
"@

[System.Net.ServicePointManager]::CertificatePolicy = New-Object TrustAllCertsPolicy
[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.SecurityProtocolType]::Tls12 -bor [System.Net.SecurityProtocolType]::Tls11

#Get iDRAC creds
$Credentials = Get-Credential -Message "Enter iDRAC Creds"

$JsonBody = @{"ResetType" = $ResetType} | ConvertTo-Json
$u1 = "https://$($idrac_ip)/redfish/v1/Systems/System.Embedded.1/Actions/ComputerSystem.Reset"

Invoke-RestMethod -Uri $u1 -Credential $Credentials -Method Post -UseBasicParsing -ContentType 'application/json' -Body $JsonBody -Headers @{"Accept"="application/json"} -Verbose


Hope it was useful. Cheers!

3 Node Hyper-V 2012 R2 Cluster Design

Below diagram shows a traditional 3 tier highly available cluster with 3 Hyper-V nodes and 2 shared storage nodes (storage in Active-Passive/ Active-Active mode) all connected via network switches.

Compute

*Hyper-V nodes are running on DELL PowerEdge R630 rack servers

Networking

*Shared storage is accessed via MPIO over two separate VLANs (61 and 62)
*VM traffic is over NIC teaming (Switch independent and dynamic)
*Live migration/ cluster network is also teamed together

Storage

*We are using DELL PowerEdge R320 with Open-E DSS V7 as storage nodes
*Each node has 8 x 10K SAS drives with RAID 5
*Storage can be either in Active-Passive/ Active-Active cluster mode
*In Active-Passive mode, only one of the storage nodes will be active. That means resources of only one storage node will be utilized at a time
*In Active-Active mode, both servers will be active and serving storage traffic
