Managing OmniSwitch 6850/6850E Series Stacks Reloading Switches Reloading the Secondary Management Module If the switch with secondary management role is reloaded, the idle switch with the lowest slot number will automatically assume the secondary role. The reloaded switch (the former secondary) will assume an idle role when it comes back up. Meanwhile, the switch with the primary management role, as well as any other idle modules in the stack, continue operations without interruption. To reload the secondary management module, use the reload command. Be sure to include the syntax secondary in the command line. For example: -> reload secondary Note. A secondary management module reload can also be scheduled for a later time or date. For information on scheduling a secondary module reload, as well as additional command details, refer to the OmniSwitch CLI Reference Guide. Primary - Slot 1 Secondary - Slot 2 Idle - Slot 3 Idle - Slot 4 1 In this stack of four switches, the slot 1 switch is the primary man- agement module. The slot 2 switch is the secondary. Slots 3 and 4 are operating in idle roles. -> reload secondary 2 The user reloads the stack's secondary management module by issuing the reload secondary command. Any data flow on the secondary switch's Ethernet is interrupted. Primary - Slot 1 Booting... Secondary - Slot 3 Idle - Slot 4 3 The idle switch with the lowest slot number-in this case, slot 3-automatically becomes the secondary management module. The slot 4 switch remains unaffected. In addition, Ethernet traffic on slots 1, 3, and 4 remains unaffected. Primary - Slot 1 Idle - Slot 2 Secondary - Slot 3 Idle - Slot 4 4 When the rebooted switch comes back up, it assumes an idle role within the stack.
