Deleting a Controller
Use the command delctrlr to delete controllers that have been added to interfaces.
When one of the controllers is deleted by using the delctrlr command, the master-slave connections and
connections associated with this controller on all the UXM cards in the switch are also deleted. VSI
partitions remain configured on the node.
The deletion of the controller triggers a new VSI configuration (internal) message. This message
includes the list of the controllers attached to the node, with the deleted controller removed from the list.
This message is sent to all active slaves in the node.
As long as one controller is attached to the node with a specific partition, the resources assigned to the
partition are not affected by deletion of any other controllers from the node. The slaves only release all
VSI resources used on the partition when the partition itself is disabled.
Deleting a Slave
When a slave is deactivated by downing the last line or trunk on the card, the NPM tears down the
master-slave connections between the slave and each of the controller ports on the node. The NPM also
tears down all the interslave connections connecting the slave to other active VSI slaves.
VC Merge on the IGX
Note Because VC merge is not supported on the UXM, y-redundancy cannot be set up using a UXM-E and a
UXM without generating a feature mismatch error. If y-redundancy is set up between a UXM-E and a
UXM, the VC merge feature cannot be enabled.
VC merge on the IGX is supported in Switch Software Release 9.3.40.
Before setting up y-redundancy on two UXM-E cards, make sure that VC merge feature support is
enabled on both cards. Both cards must have the appropriate card firmware to support the VC merge
feature.
For more information on y-redundancy on the UXM-E, see the “Card Redundancy” section on page 2-15
in Chapter 2, “Functional Overview.”
Tip Before enabling VC merge, set the minimum number of channels to 550 using the cnfrsrc command. If
this minimum number of channels is not available on the card, an error message is displayed.
To enable VC merge on the IGX, perform the following steps:
Step 1 Configure the card parameters for VC merge using the cnfcdparm slot number 2 e command.
Step 2 If you receive the error message shown below, repeat Step 1.
Card rejected cmd. VC Merge NOT enabled!
Step 3
Continue with switch configuration or management.
