Migrating A Dpc; Halting Cards; Initiate A Card Halt - Cisco ASR 5500 Administration Manual

Migrating a DPC

Migrating a DPC
When the system boots up, all DPC/UDPCs 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, 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 migration.
These instructions assume you are at the root prompt for the Exec mode.
Step 1 Initiate a DPC/UDPC migration by entering the following command:
host_name
[local]
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.

Halting Cards

Cards other than MIO/UMIOs 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.

Do not initiate a card halt for an active FSC if there are less than two active FSCs in the system. The
system returns an error message if there are less than two active FSCs. There are similar restrictions when
executing the card reboot or card upgrade commands on active FSCs. Refer to the Command Line
Interface Reference for detailed information.
