Normal System Status
The displays will vary when the system is a triple system configuration.
On a dual server system, the status command will show the system is AB, with both servers
connected to each other. A display similar to the following will appear on server A:
NRCS-A# status
A is ONLINE and has been CONFIGURED. ID is NRCS.
System is AB. Master is A.
Disk status is OK. The database is OPEN.
The system status is reported identically on both servers in the system. For instance, a
display similar to the following will appear on server B:
NRCS-B# status
B is ONLINE and has been CONFIGURED. ID is NRCS.
System is AB. Master is A.
Disk status is OK. The database is OPEN.
When the system is dual and databases are mirroring between the two servers, a story
written on one server is automatically mirrored to the database of the other server. When the
system is connected and has the normal prompt, the servers are in communication with each
other and the disk mirroring process is active.
Disconnects
If the servers disconnect from each other, the databases are no longer mirrored between the
two servers and immediate attention is required. Since mirroring has stopped, stories written
by users on server A will not be seen by users logged in to server B. There will be two
entirely separate databases.
There is no way to reintegrate two disparate databases. You must decide which database will
be retained as the master database, and the other database must be erased. The steps for
recovering from a disconnect are outlined later in “Procedures” on page 89.
