Upgrading the Software on all Active Nodes
You can centrally upgrade the software on all
active nodes in a stack. To upgrade all nodes in the stack, all nodes must be running an
ExtremeXOS release that supports stacking (ExtremeXOS release 12.0 or later).
-
Download a new ExtremeXOS software release and install it
on all nodes on the active topology using the command: download image
[[hostname | ipaddress] filename {{vr}
vrname}] {partition}
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.
-
If necessary, use the use image
{partition} {primary | secondary} command to
select the image partition (primary or secondary) into which the software was saved.
-
Restart all nodes in the new release using reboot
{[time mon day year hour
min sec] | cancel}
For
example:
download image [[hostname | ipaddress] filename {{vr} vrname}] {primary | secondary}
use image {partition} [primary | secondary]
reboot
-
Before you upgrade a stack, make sure that the active
image partition is same across all nodes.
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.
-
To run the upgraded software, you must reboot the stack
after installation with the image partition that received the software
being selected.
-
If the active partition is different on some nodes, the
action you take depends on what is stored in both partitions:
If both primary and secondary partitions have the
same ExtremeXOS release, you may use the following commands to cause a node to use the
same active image as the rest of the stack:
use image {primary | secondary} slot slot-number
reboot slot slot-number
If you are using the primary image on your master
node and some other node primary image does not contain the same
ExtremeXOS version as
your master node's primary image, you may use the command:
synchronize slot slotid
to cause the node to contain the same
ExtremeXOS versions in both partitions as
it is on the master node, and to reboot the node into the primary partition.
Hitless upgrade is not supported in a stack.
