About Interface Deletion From A San Port Channel; Deleting An Interface From A San Port Channel - Cisco Nexus 5500 Series NX-OS Configuration Manual

Configuring SAN Port Channels
When SAN port channels are created from within an interface, the force option cannot be used.
Note
After the members are forcefully added, regardless of the mode (Active and On) used, the ports at either end
are gracefully brought down, indicating that no frames are lost when the interface is going down.
To force the addition of a port to a SAN port channel, perform this task:

About Interface Deletion from a SAN Port Channel

When a physical interface is deleted from the SAN port channel, the channel membership is automatically
updated. If the deleted interface is the last operational interface, then the port channel status is changed to a
down state. Deleting an interface from a SAN port channel decreases the channel size and bandwidth of the
SAN port channel.
• If you use the default On mode to avoid inconsistent states across switches and to maintain consistency
across switches, then the ports shut down. You must explicitly enable those ports again.
• If you use the Active mode, then the port channel ports automatically recover from the deletion.
After the members are deleted, regardless of the mode (Active and On) used, the ports at either end are
gracefully brought down, indicating that no frames are lost when the interface is going down.
