Brocade IronStack management
NOTE
If any unit in the IronStack is running an incorrect version of the software, it will appear as
non-operational. You must install the correct software version on that unit for it to operate properly
in the stack. For more information, refer to “Copying the flash image to a stack unit from the Active
Controller” in the next section.
Copying the flash image to a stack unit from
the Active Controller
To copy the flash image to a stack unit from the Active Controller primary or secondary flash, enter
the following command.
Brocade# copy flash flash unit-id-pri 2
Syntax: copy flash flash [primary | secondary | unit-id-pri <unit-num>| unit-id-sec <unit-num>]
• primary - Copy secondary to primary
• secondary - Copy primary to secondary
• unit-id-pri - Copy active primary image to unit ID
• unit-id-sec - Copy active secondary image to unit ID
The unit-id-pri and unit-id-sec keywords are used to copy images to a stack member from the Active
Controller primary and secondary flash, respectively. For <unit-num>, enter a value from 1 through
8.
NOTE
You do not have to manually copy the flash image to a mismatched stack unit. For more information,
refer to “Auto Image Copy for stack units” on page 321.
Reloading a stack unit
To reload a stack unit, enter the following command.
Brocade# reload
Syntax: reload [after | at | cancel | unit-id <unit-list>]
• after - Schedule reloading after certain time period
• at - Schedule reloading at an exact later time
• cancel - Cancel scheduled reload
• unit-id - Stack members to reload. The <unit-list> variable can be a combination, such as
2,4-6,8. Tokens must be separated by a comma and there is no space.
Controlling stack topology
Because Stackable devices allow you to use one of the two ports intended for stacking as a regular
data port, you can control the size of your stack. The following example shows a stack where the
existing ring topology is changed so that only one unit in the upstream direction is connected
through a stacking port, which limits the size of the stack to two units.
