Taking the Rear Card Offline in a QFX3008-I Interconnect Device
To prevent data loss, we recommend that you take a rear card offline and power it off before removing it from a QFX3008-I Interconnect device.
The rear cards provide switching functionality for a QFX3000-G QFabric system. We recommend that you install all eight rear cards in each QFX3008-I Interconnect device for normal device operation. When you take a rear card offline, the switching capacity of the QFX3000-G QFabric system will be reduced until the rear card is replaced.
To take the rear card offline in a QFX3008-I Interconnect device:
- Log into the QFabric default partion on the Director device
and start the CLI.
[root@dg0] # cli
- Discover the device connection status and the alias name
(identifier) by issuing the show fabric administration inventory
interconnect-devices command.
root@qfabric> show fabric administration inventory interconnect-devices Item Identifier Connection Configuration Interconnect device IC-QFX3713490033 Connected Configured QFX3713490033/RE0 Connected IC-QFXB3714010454 Connected Configured QFX3714010454/RE0 Connected root@qfabric>The card must show as connected and configured in order to have an orderly shutdown.
- Issue the request fabric administration power-off
interconnect-device serial-id |alias-name fpc slot operational mode command from
the QFabric default partition CLI. This command systematically takes
the node offline and gracefully shuts down the device while preserving
system state information. Use the name of the Interconnect device
in which the rear card you want to remove is installed, and the number
of the slot from which you are removing the rear card; the slots are
numbered from
8through15. See Slot Numbering for a QFX3008-I Interconnect Device.You see output similar to the following after entering the command:
root@qfabric> request fabric administration power-off interconnect-device IC-A0004 fpc 13 STEP 1 of 6 (Acquiring lock): Acquiring lock to perform this operation Acquired lock to perform this operation STEP 2 of 6 (Performing pre-checks): interconnect-device IC-A0004 is online STEP 3 of 6 (Gracefully offlining the interconnect linecard): Gracefully offlining the fpc fpc is successfully offlined STEP 4 of 6 (Waiting for convergence): Waiting for convergence(this will take few minutes) request fabric administration power-off interconnect-device IC-A0004 Convergence complete STEP 5 of 6 (Powering-off the interconnect linecard): Now, powering-off the fpc on the interconnect-device Powered-off the fpc on the interconnect-device STEP 6 of 6 (Releasing lock): Releasing the lock root@qfabric>
Caution The final output of the request fabric administration power-off interconnect-devices serial-id |alias-name fpc slot CLI command is the following message: The device is shutting down and can be removed when the LCDs are off. Wait at least 3 to 4 minutes after first seeing this message before following the instructions in Removing a Rear Card from a QFX3008-I Interconnect Device.
