I have two ASAs 5516 in Active / Standby failover.
From my active unit, I can not ping any standby IP, except may be for failover.
Following is my config:

Imp: When i ping standby IP of management interface, in the log, I see the source as 'inside' interface's IP not management's. I have other firewalls which on which I can reach standby IPs, and the source IP ( in ping) is 'management' interface and not 'inside'.
