That is not going to be documented because there are way too many variables.

Ball park, I would expect 15-30 minutes with the following list of prerequisites:

  • All nodes got powered on around the same time, ESXi is booted, with storage controllers guestVMs running.
  • All uplinks ports (to FIs)/networking are up.
  • non-nested DNS/NTP are reachable (cluster didn't have time sync issues prior to outage)
  • No additional hardware failures, post bootup (i.e. no bad disks, etc)

Larger clusters may take longer to heal/complete resync.

 

It is important to confirm all physical servers are powered on, ESXi  is booted and not in maint mode, the storage controller guestVMs are all running.  Having a nested Vcenter, generally requires tracking down which ESXi host is associated with the Vcenter guestVM, and making sure it is started.
