Survivability
3 The data is then written to the primary flash drive.
4 When the database files in the primary flash drive are updated, data and
patches are written to the internal backup flash drive (Z:).
Note: LD 43 and 143 are not available on an IP expansion cabinet or
chassis in survival mode.
SWP, RES, and RIB commands for Survivability
To ensure the database synchronization on the main and the survivable IP
expansion cabinet(s) or chassis, the Swap (SWP), Restore (RES), and Restore
Backup (RIB) commands are modified to produce the same results on the
survivable IP expansion cabinet(s) or chassis as on the main cabinet or
chassis.
The optional parameter, [<cab#>], allows the technician to select a specific
cabinet or chassis in order to restrict the effect of the command to a specific
cabinet or chassis.
If no parameter is provided, the command is first performed on the main
cabinet or chassis. The technician is then prompted with a confirmation
request. If <YES>, the command is performed on all survivable IP expansion
cabinets or chassis.
As with the database download operation, preliminary security checks are
performed by the main cabinet or chassis against the security ID and software
release of the survivable IP expansion cabinet(s) or chassis. If these security
checks fail for any cabinet or chassis, synchronization is aborted for that
cabinet or chassis.
SWP command
The SWP command is used to swap the regular and "*.bak" copies of the
database on the primary flash drive. It restores the database to the state prior
to the most recent datadump. Figure 133 on
of the SWP command. Only one IP expansion cabinet is shown for illustration
purposes.
