Thinking about HA Active-Passive
Hello, good afternoon, thank you very much for your collaboration as always, please your help and support to clarify the following:
Thinking about HA issues, I understand that the recommendation will always be to use Active/Passive OK on that side.
I have a couple of questions about HA:
-When a FAILOVER occurs based on the example of a Link Monitor and/or a Path Monitor. The passive team goes on to take the ROLE of passive. Then let's say that the initial failover condition is validated and recovered to return the Main device to Active again, this must be done manually, right?
-Derived from the above, the issue of the preemtive is in relation to restarts, let's say when there are restarts or when an upgrade is typically performed and you must deactivate the preemtive and then restart for the upgrades, at this point when activating the Preemtive again, With the two computers already restarted and operational, the preemtive will not leave the Principal as active again, the one with the best priority, automatically or should it be manually?
I remain attentive, thank you very much as always, greetings and attentive to your comments.
With preempt enabled on both devices, the member with lowest priority # becomes active If preempt is not enabled on one or both members, fail over only happens manually (or if something fails)
