You can also use this command to prevent an audible alarm from sounding, in
the case where a known condition will set off the alarm, by muting the alarm
in advance.
If an error condition or degraded state is detected, the enclosure alarm or
buzzer will be audible. To silence the alarm, you may either set the state of the
alarm to OFF, or you may mute the alarm.
The default values are UNMUTE and OFF.
Example:
//localhost> /c0/e0/alm0 set alarm=unmute
Setting alarm audibility setting of /c0/e0/alm0 to [unmute] ...
Done.
Help Commands
The Help commands provides brief on-line help.
You can get overview help by typing Help at the top-level prompt. This
displays a brief definition of commands. (For an example, see the discussion
of the command “help” on page 135.)
You can also get help with specific commands, by entering help before an
object name, or by typing a question mark (?) at the point in a command
where you are uncertain what the attributes are.
Help with specific commands
If you enter the help command at the top level, you are considered to be in the
Shell Object, and the help command will provide help on the Shell commands
focus, show, flush, rescan, and commit. Using the help command on objects
(such as /cx, /cx/ux, /cx/px, /cx/bbu, /ex, /ex/slotx, /ex/fanx, and /ex/tempx),
displays all possible sub-commands associated with the object.
For example:
help on the controller object /cx, will display all the sub-
commands associated with the controller /cx, like this:
Note:
Some enclosures support alarms but not the mute/unmute function. For
these enclosures, using this command to set the alarm to
mute
will return an error
message indicating that the feature is not supported. For these enclosures, the
alarm is not mutable, however it can be turned OFF.
If you set this command to
unmute
for an enclosure that does not support mute,
the command will appear to complete and will not report an error. However in this
case, there is no mute setting to change to unmute.
