DAS System User Manual
The overlay has two main fields: the Diagnostics field and the File System
Check field. The default selection for both fields is Execute Each Power Up.
Both fields also have an Execute Custom selection where you can specify how
often the DAS will run the diagnostics and file system checks.
When you select Execute Custom you can specify the number of days (up to 14)
to skip before executing the diagnostics or file system check. You can also
specify the number of power up cycles that the DAS can bypass (up to five)
before executing the diagnostics or file system check. The DAS will execute the
diagnostics and file system check depending on which criteria is fulfilled first,
that is, the number of days or the number of power up cycles. The File System
Check field has a third selection that allows the DAS to execute the file system
check only after an abnormal system shut down.
Information under the BOOT ACTIVITY summarizes the most recent diagnos-
tics and file system check activity. It indicates the last time that diagnostics were
checked and the last time that the file system was checked.
Changes to the overlay take effect at the next power-on cycle.
Use function key F4: DEFAULT CHECKS to return the Diagnostics field and
the File System Check field to the default settings (Execute Each Power Up).
