ZCOM Tables and Data Structures
Interface Table
ISTIME - Time of last ZMON restart/shutdown this card.
This field contains the time (seconds since the Epoch) when ZMON last
processed a restart or shutdown request for t his card. It is used
internally by ZMON to detect and ignore multiple restart/shutdown
requests.
BC1_ADDR - First level bus converter address for this MUX interface
card
For HP9000 Series K systems the address is of the form bc1/bc/s. This
field refers to the first level bus converter address indicated as bc1. For
other systems this field is initialized to zero.
BC_ADDR - Bus converter address for this MUX interface card
This field contains the I/O b us converter address representing the I/O
bus that the MUX interface card is installed in. On systems that contain
only one I/O bus (S8x7, I30, H50, etc), this field is initialized to zero.
CARD_ADDR - Card address for this MUX interface card
This field contains the I/O card address representing the I/O slot number
that the MUX interface card is installed in. It is initialized by TTGEN
from the slot value specified in the MUX statement of the TTGEN
configuration file.
INHPA - Interface HPA value (from TTGEN)
The HPA value is built as follows:
For the Mux interfacein an HP-PBstandardbackplane, the cardaddress
is 4 x slot number. In the TTGEN configuration file, the card address is
given as BUS:SLOT (e.g., 0:48), or BUS:BUS:SLOT. Here the 10-bit Bus
Address field is translated from the 1’s complement of BUS (i.e.,
1023-BUS). The Slot field is specified by SLOT/4. The Module, Page,
Register Set, and Reg No. fields are set to 0. For the example of
BUS:SLOT=0:48, the HPA is 0xFFFB0000. For EISA standard
backplanes the address is the slot number.
