mask
The MPE maintains a set of status flags derived from various hardware fault
detects. These flags indicate such things as proper installation of cables and
functioning power supplies.
Displays a list of all the status flags. The ! character beside a status flag
indicates that there is a problem with the corresponding component (e.g. missing
cable). The * character beside a status flag indicates that the flag has been
masked. Note that hyphenated acronyms generally refer to cable detects (e.g.
HA-BP).
If one of these components suffers a detectable fault, the corresponding status
flag will cause the system to report an error.
If multiple related faults exist, internal diagnostics will determine which is
the true cause and report only that error.
The mask command provides the facilities for determining the state of these
flags and for disabling or masking a flag.
If a status flag is masked, a problem with the corresponding component will not
be detected directly. This can be used to stifle error messages in an incomplete
system.
