eDirectory Health Checks 121
B.3.2 Partitions and Replica Health
After checking the basic server health, it then checks the partitions and replica health as follows:
1. Checks the health of the replicas of the locally held partitions.
2. Reads the replica ring of every partition held by the server and checks whether all servers in the
replica ring are up and all the replicas are in the ON state.
3. Checks the time synchronization of all the servers in the replica ring, showing any time
difference between the servers.
B.4 Categorization of Health
There are three possible categories of health, based on the errors found while checking the health of
an eDirectory server:
 Normal (page 121)
 Warning (page 121)
 Critical (page 121)
The status of the health checks is logged into a log file. For more information, refer to Section B.5,
“Log Files,” on page 122.
B.4.1 Normal
All the health checks were successful and the server health is normal.
The upgrade proceeds without an interruption.
B.4.2 Warning
Minor errors were found while checking the server health.
If the health check is run as part of the upgrade, you are prompted to either abort or continue.
Warnings normally occur in the following scenarios:
 Server not listening on LDAP and HTTP ports (normal, secure, or both).
 Unable to contact any of the non-master servers in the replica ring.
 Servers in the replica ring are not in sync.
B.4.3 Critical
Critical errors were found while checking the eDirectory health.
If the health check is run as part of the eDirectory upgrade, the upgrade operation is aborted.
The critical state normally occurs in the following scenarios:
 Unable to read or open the DIB (might be locked or corrupt).
 Unable to contact all the servers in the replica ring.
