The fault screen is displayed until it is acknowledged by pressing
any F-key or cleared in the drive by other means.
12.5.1 About the Fault Queue
The drive automatically retains a history of faults that have occurred
in the fault queue. The fault queue is accessed using the OIM or VS
Utilities software.
The fault queue holds the eight most recent faults. The last fault to
occur is indicated in queue entry #1. As new faults are logged into
the queue, existing fault entries are shifted (for example, entry #1
will move to entry #2). Once the queue is full, older faults are
discarded from the queue as new faults occur.
All entries in the fault queue are retained if power is lost.
The Time Stamp
For each entry in the fault queue, the system also displays a fault
code and time stamp value. The time stamp value is the value of an
internal drive-under-power timer at the time of the fault. The value of
this timer is copied to PowerUp Marker (242) when the drive powers
up. The fault queue time stamp can then be compared to the value
in PowerUp Marker to determine when the fault occurred relative to
the last drive power up.
The time stamp is cleared when the fault queue is cleared.
Refer to section 12.8.1 for information on accessing the fault queue
using the LCD OIM.
