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 this 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 bus 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 interface in an HP-PB standard backplane, the card address 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.
