Survivability
Special text, which is displayed on the TTY of the IP expansion cabinet or
chassis, indicates when the IP expansion cabinet or chassis is operating in
survival mode. This text informs the technician of the difference between the
remote TTY's access to the main cabinet or chassis in normal mode and the
IP expansion cabinet or chassis in survival mode. The text displayed prior to
login is as follows:
OVL111 0000 IDLE
TY 00 SCH MTC BUG 21:44
SURVIVAL MODE
The text displayed on the TTY of the IP expansion cabinet or chassis after
login is as follows:
TTY 00 LOGGED IN 21:44 3/10/1999 SURVIVAL MODE
OVL000 SURVIVAL MODE
During survival mode, survivable IP expansion cabinets or chassis use a copy
of the database that was configured at the main and previously downloaded
to the survivable IP expansion cabinet or chassis. Use the Invoke Datadump
Program (EDD) command at the main cabinet or chassis, or upon startup in
normal mode, to download the database.
Data can be changed on the IP expansion cabinet or chassis while in survival
mode, but new or changed data is lost when switched back to the main cabinet
or chassis. The local datadump (EDD) is supported only on the main cabinet
or chassis.
Datadump enhancements and new commands
With the introduction of survivable IP expansion cabinets or chassis, the EDD
command is enhanced to first perform an EDD on the main and then
download the database files to each survivable IP expansion cabinet or
chassis.
Before the file transfer, the main cabinet or chassis verifies that the software
release of the survivable IP expansion cabinet or chassis matches its own
