True. These were the days, when the interesting stuff wouldn't reside in
/usr or
/etc but in $SYS$SYSTEM.
Ah, well - and then all hell broke loose and an upstart PC-botch-shop bought the producer of the best processor and the best working cluster in the world. Like Old Joes Garage purchasing Porsche along with its racing team division.
I use "directory" exclusively as i deal only with "file system entities". I simply have nothing to do with "GUI concepts", "metaphors" or other crutches for the technically impaired.

ibdm-topo-file
IBDM-TOPO-FILE(1) IB DATA MODEL PACKAGE IBDM-TOPO-FILE(1)
NAME
ibdm-topo-file - 1IBDM Topology File
DESCRIPTION
The topology file describes the IB connectivity and systems included in the network. It serves two purposes:
1. Support for arbitrary system names to be later used in every report that IBDM generates.
2. Connectivity verification: The specified network topology is verified against the discovered one. Mismatch errors resulting from missing
cables and/or wrong connections are reported by IBADM.
The topology file is composed "system" sections. Each such section describes the connectivity of one system to other systems in the
network. The first line of each section is a declaration of the system composed of a system-type, its system-name section, and optional
configuration details. The lines to follow until the next empty line describe the connections between this system ports to the other
systems. The following is a formal definition of a system section syntax.
An example is listed afterwards.
SYSTEM-TYPE SYSTEM-NAME [CFG: <b1>=<modifier>, [<b2>=<modifier>]...]
LOCAL-PORT-PANEL-NAME -> REM-SYS-TYPE REM-SYS-NAME REM-PORT-PANEL-NAME
LOCAL-PORT-PANEL-NAME -> REM-SYS-TYPE REM-SYS-NAME REM-PORT-PANEL-NAME
LOCAL-PORT-PANEL-NAME -> REM-SYS-TYPE REM-SYS-NAME REM-PORT-PANEL-NAME
. . .
SYSTEM-TYPE SYSTEM-NAME [CFG: <b1>=<modifier>, [<b2>=<modifier>]...]
LOCAL-PORT-PANEL-NAME -> REM-SYS-TYPE REM-SYS-NAME REM-PORT-PANEL-NAME
LOCAL-PORT-PANEL-NAME -> REM-SYS-TYPE REM-SYS-NAME REM-PORT-PANEL-NAME
. . .
. . .
Where:
SYSTEM-TYPE and REM-SYS-TYPE
Any system that has a corresponding IBNL definition. See man ibdm-ibnl-file
SYSTEM-NAME
The name of the system described in this topology file section.
LOCAL-PORT-PANEL-NAME
The name of the local system port. The numbers printed on the front panel are used together with Ln for Leaf no. N or Sn for Spine no.
N.
REM-SYS-NAME
The name of the system connected to the local port.
REM-PORT-PANEL-NAME
A name of the remote system port. We use the numbers as printed on the front panel and Ln for Leaf number N or Sn for Spine number N.
EXAMPLE
The following is a topology file for a simple cluster with one 24 port switch and two HCAs. The firts HCA named H-1 and connect to the
fabric with its two ports. The second HCA named H-2. The switch is of type MTS2400 and is named S-1
MTS2400 S-1
P1 -> MT23108 H-1 P1
P2 -> MT23108 H-1 P2
P24 -> MT23108 H-2 P1
OPTIONAL CFG SECTION
This section in the system declaration line describes the special customization of each board of the system.
That is the CFG string is a set of comma-separated sub-fields. Each sub-field describes some special configuration of a corresponding
system board. The actual semantics of the specific board modifiers is defined by the IBNL of the specific system.
EXAMPLE
The following is an example of a definition-line in a topology file of the MTS9600 switch system. This switch system can have up to eight
leafs and four spines. This example of the MTS9600 lacks (R) leafs no.6,7 and 8, and lacks spines no. 3 and 4.
MTS9600 PartialGz1 CFG: leaf3=R,leaf5=R,leaf7=R,spine1=R
