1. Implement Azure specific HA steps as documented:

RHEL: https://learn.microsoft.com/en-us/azure/sap/workloads/high-availability-guide-rhel-pacemaker?tabs=msi#configure-pacemaker-for-azure-scheduled-events

sudo pcs property set node-health-strategy=custom

sudo pcs constraint location 'regexp%!health-.*' \

sudo crm_attribute --node prod-cl1-0 --name '#health-azure' --update 0
sudo crm_attribute --node prod-cl1-1 --name '#health-azure' --update 0

sudo pcs resource create health-azure-events \

op monitor interval=10s timeout=240s \
op start timeout=10s start-delay=90s

sudo pcs resource clone health-azure-events allow-unhealthy-nodes=true failure-timeout=120s

2. Add additional check for pcmk_host_map to remove it if VM name is equal to hostname, or generate as per documentation:

The 'pcmk_host_map' option is required in the command only if the hostnames and the Azure VM names are not identical. Specify the mapping in the format hostname:vm-name.
