3.5.3 UPS Devices Status Display
3.5.3.1 UPS #
The UPS number field of the UPS DEVICES STATUS portion of the status display is simply an ordinal index number
assigned by UPSUTIL to the UPS devices, for convenience in referring to the UPSs. It has no functional significance.
3.5.3.2 LDEV #
The LDEV number field (column) of the status display shows the logical device numbers
associated with the UPSs
configured on the system. These LDEV numbers are the "handles" by which I/O devices are
known in the MPE/iX File
System. LDEV numbers are assigned to the UPS devices during the I/O configuration process of system configuration.
3.5.3.3 Alloc (Allocated Indicator)
The allocated field (column) of the status display shows whether or not a UPS device has been successfully
allocated to
(i.e. is now "owned" by) the UPS Monitor Process.
In order to control and monitor a UPS device, the device must first be allocated to the UPS Monitor Process. Allocation
is
performed in the MPE/iX File System, via the HPFOPEN intrinsic. If allocation succeeds, then the UPS Monitor
Process will attempt to monitor that UPS device, and a value of Yes will be displayed in the Alloc field.
If allocation
should fail, then the UPS Monitor Process can not monitor that UPS device.
A value of No will appear in the Alloc column
in that case.
3.5.3.4 Init (Initialized Indicator)
The initialized field (column) of the status display shows whether or not a UPS device has been
successfully initialized (i.e.
"brought online") by the UPS Monitor Process.
A value of Yes in this column indicates that the UPS device has been successfully initialized by the UPS Monitor
Process, and is in a "ready to be monitored" condition.
A value of No in this column indicates that either initialization of the UPS device failed (in which case there will be
log
entries in the system log file showing what errors were encountered during initialization), or that
initialization is in progress but not yet completed (in which case, a later repetition of the STATUS command
will show
a Yes in this column, denoting completion of initialization).
