Initiating a Full System Check
A Full System Check verifies and synchronizes the entire protected file set by performing the same block level
check of all the files identified by file filters in the initial startup synchronization and verification.
Procedure
1 Click Full System Check in the File Hierarchy pane to initiate a Full System Check.
A confirmation dialog asks you to confirm the request and warns you that depending on the amount of
data under protection, this task can take a long time to complete (possibly a number of hours).
Note While a Full System Check (FSC) is in progress, a manual failover cannot be initiated, and in this
case the recovery point time simply shows the age of file updates which have not yet been applied on the
passive node. When the FSC is complete, then the recovery point shows the age of the oldest file update
on the active node which has not yet been transmitted to the passive.
2 Click Yes to perform the check.
Note VMware recommends that once an FSC is initiated, you allow it to run to its conclusion. Canceling
the FSC leaves the file system status Unchecked. Depending on the amount of data, resynchronization
may take substantial time to complete. A manually initiated failover is not permitted until after the task is
complete and the File System Status is Synchronized.
Enabling Fast Check
Fast Check is a process used by vCenter Server Heartbeat to rapidly verify files between nodes prior to starting
applications. Fast Check compares file time stamps and attributes rather than check sums of the data thereby
accelerating startup and synchronization processes. If the time stamp or attribute check fails, than normal
verification and synchronization processes will initiate. Fast Check allows you to configure the length of time
to wait for Fast Check to complete before starting applications.
Fast Check is beneficial after a graceful shutdown where servers were synchronized before shutdown. Fast
Check allows the node to check file synchronization rapidly and start to service clients. If Fast Check detects
files that are out-of-sync, it initiates a full Verify and Synchronize process to resynchronize your data.
Procedure
1 Navigate to Data: Replication.
2 Click Configure.
3 Select the Fast Check tab.
4 Select the Use Fast Check check box.
5 Configure 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 configured in addition to Controlled Shutdown, vCenter Server Heartbeat can
be configured to perform an unattended restart. For more information about Controlled Shutdown, see
“Controlled Shutdown,” on page 72.
