Initiating a Full System Check
You can verify and synchronize the entire protected le set using the Full System Check feature of vCenter
Server Heartbeat Console. A Full System Check performs the same block level check of all the les set by the
le lters in the initial startup synchronization and verication.
Procedure
1 Click Full System Check in the File Hierarchy pane to initiate a Full System Check.
A conrmation dialog asks you to conrm the request and warns you that depending on the amount of
data under protection, this task can take a long time to complete (for example, a number of hours).
2 Click Yes to perform the check.
Note Once a Full System Check is initiated, allowing it to run to its conclusion is strongly recommended
because canceling leaves the le system status Unchecked. Depending on the amount of data,
resynchronization may take substantial time to complete. Switchover is not permitted until after the task
is complete and the File System Status is Synchronized.
Enabling Fast Check
The Fast Check process is used by vCenter Server Heartbeat to rapidly verify les between servers prior to
starting applications. Fast Check compares le time stamps and attributes rather than the check sums of the
data thereby accelerating the startup and synchronization process. If the time stamp or attribute check fails,
than the normal verication and synchronization process will initiate. Additionally, you can congure the
length of time to wait for Fast Check to complete before starting applications.
Fast Check is benecial after a graceful shutdown where severs were synchronized before shutdown. Fast
Check allows the server to check the le synchronization rapidly and start to service clients. If Fast Check
detects les that are out-of-sync, it initiates the full verify and synchronization process to resynchronize your
data.
Procedure
1 Navigate to Data: Replication.
2 Click Congure.
3 Select the Fast Check tab.
4 Select the Use Fast Check check box.
5 Congure Maximum Application Delay. This is the length of time vCenter Server Heartbeat will delay the
startup of the application while it attempts to establish replication between the active and passive nodes.
6 Click OK.
Note When Fast Check is congured in addition to Controlled Shutdown, vCenter Server Heartbeat can
be congured to perform an unattended restart. For more information about Controlled Shutdown, see
“Controlled Shutdown,” on page 61.
