issues are encountered due to improper download of Adv firmware to a stack
containing legacy N3000 Series switches, recover the stack by downloading
AdvLite (itb) firmware.
To add a new member to an AdvLite or Adv mixed stack, load the new
member with an ITB image, power off the unit, cable the new member into
the stack and power it on. Then perform stack firmware synchronization
using the boot auto-copy-sw command from the mixed stack master. Do not
fail over to the new member prior to performing stack firmware
synchronization.
To upgrade an AdvLite mixed stack to Adv mono-culture stack using the .stk
firmware, power off the stack, re-cable the stack with the legacy N3000
switches removed from the stack (only N3000E-ON and N3132PX-ON
switches can operate with the Adv firmware) and power on the stack starting
with the desired stack master unit. Once the stack is fully powered, use the
clear config command to remove the configuration of the units that are no
longer participating in the stack. The no member/no slot commands in stack
configuration mode also clear the stack member configuration, however,
other configuration that references those members is not cleared and may
cause issues on a reboot of the stack.
After the member configuration has been removed for all N3000 Series
switches and the configuration has been saved, it is possible to download
N3000Advv6.5.1.X.stk firmware to the stack master. Once downloaded, the
master unit will distribute the images to other members of the stack. Use the
show bootvar [unit] command to display the stack unit firmware. After code
distribution is complete, reboot the stack.
This same technique may be used on the legacy N3000 switches that were
configured in an AdvLite stack to allow them to download mono-culture
N3000 (stk) firmware.
