Brocade IronStack management
The stack unconfigure and stack unconfigure rollback commands are unrelated and recover
different startup-config.txt files. Both commands permanently delete the current startup-config.txt
and replace it with a pre-stacking (pre-05.X) startup-config.txt file.
NOTE
When you issue the stack unconfigure rollback command to recover the previous startup-config.v4
file, DO NOT issue a write memory command, as write memory will overwrite the recovered file. You
should reboot from a pre-5.X image without doing a write memory.
If you enter the erase startup-config or stack unconfigure clean commands, all startup-config
text-related files, such as startup-config.v4 and startup-config.old are erased. You will no longer be
able to recover pre 5.X startup-config.txt files.
Syntax: stack unconfigure rollback [<stack-unit> | all | me]
• <stack-unit>- Recover the version 4 startup-config file for the stack member with this ID
• all - Recover the version 4 startup-config file for every unit including this unit
• me - Recover the version 4 startup-config file for this unit only
Displaying IronStack information
This section describes the show commands for an IronStack, including output examples and field
descriptions.
Displaying IronStack flash information
Use the show flash command to display flash memory information for all members of a stack, or for
a specified stack member.
Syntax: show flash <stack-unit>
Output from the show flash command for a stack resembles the following (for a stack with three
members).
From the Active Controller for the entire stack:
