Disconnects

Jul 13 07:46:25 nrcs-a disconnect: B COMPUTER DISCONNECTED
In addition to console warning messages, a warning message is broadcast to all users
currently logged in to the system via a popup window at the workstations.
Types of Disconnect
When the servers disconnect, one may disconnect from the other, or they may both
disconnect from each other.
If they have disconnected from each other, each will report that it is a single system, with
itself as the master:
NRCS-A# status
A is ONLINE and has been CONFIGURED. ID is NRCS.
System is A. Master is A.
Disk status is OK. The database is OPEN.
The single system status is reported identically on both servers:
NRCS-B# status
B is ONLINE and has been CONFIGURED. ID is NRCS.
System is B. Master is B.
Disk status is OK. The database is OPEN.
The other possibility is that servers will disconnect, but one of the servers will not note the
disconnect. In this case, one will report that the system is single while the other states the
system is still AB.
Regardless of the report, once one of the servers has disconnected, the system must be
recovered following the procedures in this chapter. The steps outlined are the only way to
recover and get the servers back in mirror.
c
If the system has disconnected, you cannot simply reboot the servers and bring it back
up normally. Rebooting and connecting two servers together after a disconnect can
lead to database corruption!
