Note
ExtremeXOS offers the ability to synchronize a non-master slot from the master individually, but it does not support the upgrade of the entire stack with one image download to the master.download image [[hostname | ipaddress] filename {{vr} vrname}] {primary | secondary} use image {partition} [primary | secondary] reboot
To determine the active partition selected on all nodes and the ExtremeXOS versions installed in each partition, use the show slot detail command. You can install the image only on the alternate image partition and not on the active image partition.
use image {primary | secondary} slot slot-number reboot slot slot-number
Hitless upgrade is not supported in a stack.
