F5 Failover
Apologies for what is probably a really basic question but I've just inherited this with minimal handover. Anyway, here goes:
We have two F5 LTM's in a Sync-Failover pair. They're load balancing some critical production services. They are automatically sync'ed We need to power one (the current primary) down to physically move it in a rack. Management is very twitchy about risks to live services as there have been a few unplanned outages (not the F5's) in recent weeks.
As far as I can see from the documentation, powering the primary down automatically fails over to the secondary. What is not clear is if there is any loss of service during the failover. One document says no another says there might be. It's also not clear whther it's better to manually fail the service over to the secondary before powring off the primary.
So I have two questions. 1. Should I just power off the primary or manually fail the service over and then power it off? 2. In either case what is the risk of any service outage?
