Q: How are static IP addresses handled by Azure Site Recovery?
A: Azure Site Recovery has several replication channels available for site-to-site (your sites). In Windows Server 2012 and later, for Hyper-V to Azure, Azure Site Recovery uses Hyper-V Replica; for VMware to Azure, it uses InMage Scout. Each approach handles static IP addresses differently.
For site-to-site, if a virtual machine has a static IP address, then Azure Site Recovery automatically reserves an IP address for the virtual machine when protection is enabled. This IP address is injected into the virtual machine during a failover.
For site to Azure, you would perform the IP address injection as part of your runbook. The following code shows an example Azure Automation runbook that sets a virtual machine with a static IP address.
workflow SavillTestStaticIP
{
param(
[Object]$RecoveryPlanContext
)
$AzureConnectionName = "SavillTech Internal Consumption"
$VMMVMGUID = "3c396415-0fba-4a00-nnnn-nnnnnnnnnnnn";
$IP = "10.7.115.14"
Connect-Azure -AzureConnectionName $AzureConnectionName
Select-AzureSubscription -SubscriptionName $AzureConnectionName
$VMContext = $RecoveryPlanContext.VmMap.$VMMVMGUID
Write-Output $VMContext
if ($VMContext -ne $null)
{
InlineScript
{
Get-AzureVM -ServiceName $Using:VMContext.CloudServiceName -Name $Using:VMContext.RoleName | `
Set-AzureStaticVNetIP -IPAddress $Using:IP | Update-AzureVM
}
}
}
Note that the actual virtual machine to be modified is automatically fetched from the recovery plan and stored in the $VMContext variable.
