Figure 81 - Sample Fault Screen on the OIM
The fault screen is displayed until it is acknowledged by pressing any F-key or
cleared in the drive by other means.
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 moves 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.
See Accessing the Fault Queue
on page 226 for information on accessing the fault
queue using the OIM. Refer to the VS Utilities Getting Results Manual,
publication D2-3488
, for information on accessing the fault queue using
VS Utilities software.
