Applying an Image Profile to the host
The whole purpose of creating an Image Profile is to assign it to a host and apply it. This is particularly useful when performing upgrades or driver updates on Auto Deployed ESX Servers.
How to do it…
The following procedure will guide you through the steps required to assign and apply an Image Profile to an ESX Server.
- Use the cmdlet
Connect-VIServerto add the vCenter Server to the PowerCLI session.Connect-VIServer -Server vcenter51 -User Administrator -Password pass123 - Use the
Get-VMHostcmdlet to fetch a list of ESX Servers inMaintenancemode.Get-VMHost –State Maintenance
- Save the output of the
Get-VMHostcommand to a user-defined variable.$esxhost = Get-VMHost -State Maintenance - Use the
Apply-EsxImageProfilecmdlet to apply the Image Profile to the ESX Servers.Apply-ESXImageProfile -ImageProfile "Profile001" -Entities $esxhost - Check whether the ESX Server is compliant with the created profile.
Test-DeployRuleSetCompliance -VMHost $esxhost
- Assign the compliance test output to a user-defined variable and then use that to do the repair (remediate) operation.
$compliance_result = Test-DeployRuleSetCompliance -VMHost $esxhost - Use the cmdlet
Repair-DeployRuleSetComplianceto remediate the ESXi server.Repair-DeployRuleSetCompliance $compliance_result[0]
How it works…
Applying an Image Profile to an ESXi host is a method to update software changes, such as a driver update. The hosts need to be in 'maintenance mode' for this to be done. Although the host is checked for compliance and remediated, the software change (for example, the inclusion of a newer device driver version) is not immediately seen by the ESXi host. The ESXi host will start using the updated image only during its next reboot.
