Invalid or Missing Fault Displays and Event Logs
Invalid or lost notifications may occur when the client system’s connection
with a subsystem is broken. The client system receives notification for most
changing subsystem faults at monitored intervals. This means that if the client
system is no longer notified of subsystem faults, then changes to that
subsystem will not be displayed in the client system’s Navigation Tree, Storage
window, and Windows NT Event Viewer.
For example, while the client system’s connection is broken with a subsystem,
you will not receive event logs pertaining to that subsystem, except to say that
the connection has been broken.
The following list provides the reasons for broken connections. After you have
fixed the physical problem that is listed below, you will need to close and
reopen the Storage Window to obtain the latest status.
■ For RAS connections - Remote Access Service (RAS) connections are
not full time. Events that occur when there is no RAS connection are not
logged to the Windows NT Event Logging facility.
■ For serial controller connections - There may be a bad or missing serial
cable. To repair this situation, replace or plug in the cable.
■ For host port SCSI connections - There may be a bad or missing SCSI
host cable. There may be no logical units configured on the controller
that was selected at the time of Client startup.
■ For network connections - Agent may be missing or not running. There
may be network discontinuity. The Agent may not be properly
configured for your Clients.
■ The controller may have halted, reset or hung - To repair this situation,
restart or replace the controller.
■ The virtual disk being used for communicating with the subsystem is no
longer available.
