We have configured Mirroring on SQL server 2008 R2 as HA on different site and today I saw on Principle DB server that all Databases are in disconnected mode so tried lot and then finally stopped and restarted SQL server Service.
Then opened SQL Management studio and surprised to see databases status was (In Recovery), waited for some and tried by refresh but no change in database status. Even databases was not accessible
So executed command
ENDPOINT Mirroring STATE
Clicked on refresh button and seen all databases status changed to (Principal, Synchronized) J
