Backing Up the System Configuration
Important
Backing Up the System Configuration
Prior to replacing a failed card of any type, it is good practice to save the current configuration to an external
USB device or remote network location.
Refer to Verifying and Saving Your Configuration in the System Administration Guide for detailed instructions
Synchronize File System
To assure that the configuration files on both MIO/UMIOs are identical, run the Exec mode filesystem
synchronize all command.

Preparing a Card for Replacement
To minimize service disruptions, traffic currently being processed by a failing or failed circuit card should be
switched to another card. You have the following options based on the type of card being replaced:
• MIO/UMIO – If the active MIO/UMIO fails, a switchover to the standby MIO/UMIO is automatic. In
• DPC/UDPC and DPC2/UDPC2 – An Exec mode card busy-out slot_number command moves processes
• DPC/UDPC and DPC2/UDPC2 – In the event of the critical failure of a DPCx/UDPCx, tasks will be
• FSC – The FSCs are configured for n+1 redundancy. When an active FSC fails, an automatic switchover

an issue arises that is not severe enough for the system to perform an automatic migration, a manual
migration can be initiated using the Exec mode card migration from original_slot# to final_slot#
is made to the standby FSC. At least one FSC must be in standby mode prior to initiating a switchover.
In the event that an issue arises that is not severe enough for the system to perform an automatic
switchover, a manual switchover can be invoked by executing the Exec mode card switch from
slot_number to slot_number command.
An FSC-200GB (equipped with two 200GB SSDs) can be replaced with an FSC-400GB (equipped with
a single 400GB SSD) only if the StarOS release supports the non-RAID 0 configuration of the FSC-400GB.
