304 Survivability
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 software release. If this check fails, the download operation is aborted
for that cabinet or chassis.
The data files are loaded from the primary (C:) drive of the IP Expansion
Cabinet or Chassis to protected memory when a switchover to survival mode
occurs. The database files downloaded from the main are used only when
the survivable IP Expansion Cabinet or Chassis switches to survival mode.
DWL command (download)
If the download fails, the system prints a message that indicates on which
cabinet or chassis the failure occurred. The download can be reattempted
using the new command
DWL [<cab#>] . This command triggers the
transfer of the database to the cabinet or chassis specified as a parameter,
without performing another datadump on the Main Cabinet or Chassis.
The DWL command is available in LD 43:
DWL [<cab#>]
where
cab# = specified survivable IP Expansion Cabinet or Chassis
Programming the cab# parameter is optional. If omitted, the database is
downloaded to all connected survivable IP Expansion Cabinets or Chassis.
EDD LCL command (local EDD)
The Invoke Datadump Program (EDD) command supports the Invoke
Datadump Program Local (EDD LCL) command. It performs a local
datadump where data is dumped only on the Main Cabinet or Chassis. The
databases on the survivable IP Expansion Cabinets or Chassis are not
updated. This operation is used when the database changes are tested by
the technician prior to downloading them to the survivable IP Expansion
Cabinets or Chassis.
