The following configuration guidelines apply when synchronizing the active and standby CPMs on the 7210 SAS-R6 and 7210 SAS-R12 systems:
The active and standby CPM should boot from same boot drives (cf1:\, cf2:\, or uf:\). For example, if the active CPM is booted from cf1:\, the standby CPM must use cf1:\ to bootup. Although it is possible to make the CPMs operational by booting them using any drive on active and standby, Nokia recommends that the same drives should be used to boot the system.
The user should ensure that a valid bootstrap image (boot.tim) and BOF (bof.cfg) exist in the cf1:\, cf2:\, or uf1:\ drive of both active and stand-by CPM cards. The user must verify that bof.cfg resides on the same drive as the boot.tim.
The TiMOS application images (cpm.tim and iom.tim) and the configuration file can reside in any location (local or remote), but the locations in the BOF should be configured identically on both active and standby CPM for primary, secondary, and tertiary locations.
Boot-env synchronization must be performed before config synchronization. To do so, run the admin redundancy synchronize boot-env command, followed by the admin redundancy synchronize config command.
Synchronization can only occur locally between compact flash drives cf1:Active to cf1:Standby, cf2:Active to cf2:Standby, and uf1:Active to uf1:Standby. Synchronization across different drives is not supported.
If the active and standby CPM are not synchronized for some reason, users can manually synchronize the standby CPM by running the admin redundancy synchronize boot-env CLI command, and rebooting the standby CPM by running the admin reboot standby command.
