vCenter 6.5 tip: Enabling vCenter HA? do so when things are quiet in your environment

Picked up this useful tip from the vCenter Server HA performance and Best Practices guide (see – http://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/techpaper/vcha65-perf.pdf)

Will see on Pg 23 it will refer to the fact that:

“As a best practice, it is highly recommended to pick a time period with a very light workload to enable VCHA. Otherwise, the newly cloned Passive node PostgreSQL DB could lag behind too much and not be able to catch up with the Active DB due to transaction logs on the Active DB getting purged on the Active node. We are working on adding archivelog support to address this issue in upcoming releases.”

Sensible advice, might mean weekend work for some folk mind 😦
