TLX48 2RU KVM Matrix Switch Product Manual

Rev. B, May 2022
At system power up, after initial boot-up, the
Primary Controller Card
will only evaluate its Partition Table
(upstream.csv file) once upon becoming active. The
Back-Up Controller Card
will NOT evaluate its Partition
Table (upstream.csv file) at initial boot-up, but it will when a switchover occurs from Primary Active to Back-Up
Active. If an
upstream.csv
file is found, a log entry to the
deamon.log
file is made indicating “Partition
ENABLED.
” If no file is found, then a log entry of “Partition DISABLED” is made.
The inactive Back-Up Controller Card will not verify its Partition Table (csv file), so it will not log error messages
with current time stamp entries until it becomes active. Also, any errors that occur during the Partition Table
evaluation process will be logged as “error” with a
field and line invalid
identifier. The
daemon.log file
will be at
the following location on the controller card:
/var/log/daemon.log
.
For access to the
daemon.log
file via SSH, refer to THE NETWORK INTERFACES section of this manual on pg.
for correct IP addresses of controller cards when in Primary Active or Back-Up Active mode.
To verify the
system’s
Partitioning policy
, Thinklogical recommends the following:
1) Review the
daemon.log
file on the active controller card and correct any errors in the Partition Table
before implementing multiple levels of security classification domains on the same Matrix Switch.
2) Fully verify the
Partitioning
on the active Primary Controller Card before implementing multiple levels of
security classification domains on the same Matrix Switch.
3) In a redundant system, make the Back-Up Controller Card active by disconnecting the LAN cable from
the Primary Controll
er Card’s LAN port. Check the
daemon.log
file on the Back-Up Controller Card for
any errors in the Partition Table and correct them before implementing multiple levels of security
classification domains on the same Matrix Switch
using the Back-Up Controller Card.
4) Fully verify the Back-
Up Controller Card’s
Partitioning Domains
before implementing multiple levels of
security classification domains on the same Matrix Switch.
There are cases where updates to the Partition Table need to be made in an active system.
When an
update is made to the table, the Controller will not evaluate the updated table until the procedures outlined below
are followed.
When updates are made to the Partition Table in a
non-redundant system
, Thinklogical recommends the
following
(This procedure will be disruptive to system connections)
:
1) Update the Partition Table of the Primary Controller Card.
2)
Take the Primary Controller Card out of service by following guidelines in the “Safely Remove an Active
Controller Card” section of this document on pg.
.
When updates are made to the Partition Table in a
redundant system
, Thinklogical recommends the following
(This procedure will NOT be disruptive to system connections)
:
1) Update the Partition Table of the inactive Back-Up Controller Card.
2)
Take the Primary Controller Card out of service by following guidelines in the “Safely Remove an Active
Controller Card” section of this document on pg.
. This will cause the Back-Up Controller Card to
become active and evaluate its Partition Table.
3) Update the Partition Table of the inactive Primary Controller Card with the same table used for the Back-
Up Controller Card.
4) Extract and re-inserted the Primary Controller Card back into the chassis to cause the system to make the
Primary Controller Card the active controller and begin using the updated Partition Table. Ensure that the
LAN connection to the Primary Controller Card is restored promptly.
Note: When using a Back-Up Controller configuration, both controllers must have the same
Partition Table file(s) to maintain the security of the system.
