Relocating an AHV cluster to a new datacenter while maintaining the same IPs requires careful preparation to ensure minimal disruption and data integrity. The following steps are essential:
* Stop all Nutanix Files clusters:
* Nutanix Files clusters must be stopped to ensure that there are no ongoing file operations that could be disrupted during the relocation. This prevents data corruption and ensures a clean shutdown of file services.
* Shut down all user VMs in the cluster:
* Shutting down all user VMs ensures that there are no active workloads that could be interrupted.
This step is crucial to prevent data loss and ensure a smooth transition when the cluster is powered up in the new datacenter.
* Reconfigure IPMI and Relocate LDAP (Not Required):
* Reconfiguring IPMI is not necessary if the IPMI interfaces are not affected by the physical relocation.
* Relocating the linked LDAP server is also unnecessary unless the LDAP server itself is moving or changing its network configuration.
By following these steps, the administrator ensures that the cluster can be relocated safely with minimal risk of data loss or service interruption.
