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.
The EDD LCL command has the same effect as the former Option 11C EDD
command. Its sequence of operations is as follows:
1 Prior to an actual dump, the main cabinet or chassis performs a security
check. If the security check fails, the datadump operation is aborted.
2 If the security check passes, the existing database files on the primary
flash drive are renamed with the extension ".bak".
