Troubleshooting secure-setup
Secure-setup can be used to form linear and ring stack topologies. For information about the
procedure, refer to “Scenario 1 - Three-member IronStack in a ring topology using secure-setup” on
page 250. During this procedure, if secure-setup does not detect all the units that should be
detected, perform the following checks:
• Make sure that all the cables are properly connected
• Make sure that all the relevant ports are in UP state
• Make sure that all the units are running the same image
• Make sure that you issue the stack enable command only on the unit that will serve as the
Active Controller
• Make sure that stack disable is not configured on any prospective members
• Make sure that the connection is sequential (refer to “Brocade IronStack terminology” on
page 237, Sequential Connection)
If secure-setup times out (this may happen due to inactivity), you will not be able to make any
changes in your configuration or stack topology until you restart the session by entering the stack
secure-setup command.
The unit discovery process is triggered when secure-setup is initiated. However, if the stack unit is
placed in a topology where another unit in the stack is already running the discovery process, the
current discovery process is terminated. If this is the case, you will see a message similar to the
following.
"Topology discovery is already in progress originated from <mac-address>. Please
try later."
This means a discovery process is already active and was initiated from the unit with the
<mac-address> mentioned in the message. You will need to re-issue secure-setup.
If there is already an active discovery process, secure-setup may not discover all the intended units.
If this is the case, you will need to restart the secure-setup process.
Troubleshooting unit replacement issues
If you are unsuccessful in building a stack using the automatic setup process (refer to “Scenario 2 -
Three-member IronStack in a ring topology using the automatic setup process” on page 254), or
adding or replacing a unit in a stack, consider the following issues:
• Make sure that the number of units in your stack does not exceed the maximum of 8
• Make sure that the replacement unit is a clean unit (does not contain a startup-config.txt file)
• Make sure that the replacement unit running configuration does not contain “stack enable”
• Make sure the replacement unit running configuration does not contain “stack disable”
• Make sure that the configurations of the stack ports on the Active Controller match the
physical connections to the unit
