You will receive the following prompt:

Step 2

Press Y to start the switchover.

Step 3

Verify that the busy-out was successful by entering the show card table command at the Exec mode prompt:

Check the entry in the Oper State column next to the DPC/UDPC or DPC2/UDPC2 just busied-out. Its state should be

Standby.

Migrating a DPC

When the system boots up, all DPC/UDPCs or DPC2/UDPC2s enter the "standby" mode. The standby mode

indicates that the card is available for use but is not configured for operation. Installed components can be

made active through the software configuration process. Cards that are not configured to enter the "active"

mode will remain in standby mode for use as redundant components.

In the event of the critical failure of a DPC/UDPC or DPC2/UDPC2, tasks will be automatically be migrated

from the active card to a redundant card in standby mode.

In the event that an issue arises that is not severe enough for the system to perform an automatic migration,

a manual migration can be initiated. Follow the instructions below to manually initiate a DPC/UDPC or

DPC2/UDPC2 migration. These instructions assume you are at the root prompt for the Exec mode.

Step 1

Initiate a DPC/UDPC or DPC2/UDPC2 migration by entering the following command:

[local]host_name#

You will receive the following prompt:

Are You Sure? [Yes|No]:

Step 2

Press Y to start the migration.

Step 3

Verify that the migration was successful by entering the show card table command at the Exec mode prompt.

Check the entry in the Oper State column next to the packet processing card that was just migrated from. Its state should

be Standby. The state of the packet processing card migrated to should be Active.

Use the show rct stats verbose command to review planned recovery (migration) statistics.

Cards other than MIO/UMIOMIO2s that are in either the Active or Standby modes can be halted. Halting

these cards places them into the "offline" mode. In this mode, the card is unusable for session processing as

either an active or redundant component.

If a card in the active mode is halted, its tasks, processes, or network connections will be migrated or switched

to a redundant component prior to entering the offline mode.

This section describes how to initiate a card halt and restore halted components.
