ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
If you download and install the software image on the non-active partition, you do not need to
●
reboot the switch.
If you install the image at a later time, use the following command to install the software:
●
install image <fname> {<partition>} {msm <slotid>} {reboot}
7 Verify that the new backup MSM comes up correctly and that the MSMs are synchronized using the
following command:
show switch
The current state indicates which MSM is the primary (displayed as MASTER), which MSM is the
backup (displayed as BACKUP), and if the backup MSM is synchronized with the primary MSM
(displayed as In Sync).
8 Optionally, initiate failover from the new primary MSM to the new backup MSM using the following
command:
run msm-failover
When you failover from the new primary MSM to the new backup MSM, this optional step restores
the switch to the original primary and backup MSM.
9 Optionally, confirm that the failover is successful by checking the current state of the MSMs using
the following command:
show switch
You can also perform a hitless upgrade on ExtremeWare XOS modular software packages (.xmod files).
To perform a hitless upgrade of a software package, you must install the core software image first, and
the version number of the modular software package must match the version number of the core image
that it will be running with. For more information about hitless upgrade, see the ExtremeWare XOS
Concepts Guide.
Hitless Upgrade Caveats for the BlackDiamond 8800 Series Switch Only. The following is a summary of
hitless upgrade caveats for only the BlackDiamond 8800 series switch:
When you initiate failover, the MSM I/O ports on the original primary MSM are not available
●
during and this MSM I/O subsection is power cycled. It takes about 2 minutes for these MSM I/O
ports to be able to pass traffic again.
If you attempt a hitless upgrade between major releases, the switch warns you that the upgrade is
●
not hitless. You can either continue the upgrade or cancel the action. If you continue the upgrade,
the primary MSM downloads the new image to the I/O module and reboots them.
If you are running ExtremeWare XOS 11.4 or earlier, do not attempt to perform a hitless upgrade to
●
ExtremeWare XOS 11.5 or later. On the BlackDiamond 8800 series switch, these versions of software
are incompatible and cannot exist on MSMs installed in the same chassis even during the hitless
upgrade process. If attempted, the backup MSM enters the non-operational state.
To recover from the non-operational state, do the following:
a From the primary MSM, use the
of software.
b To confirm the MSMs are synchronized, use the
The current state indicates which MSM is the primary (displayed as MASTER), which MSM is the
backup (displayed as BACKUP), and if the backup MSM is synchronized with the primary MSM
(displayed as In Sync).
After you recover from the non-operational state and confirm the MSMs are synchronized, perform a
normal code upgrade to install and upgrade the image on the switch. For more information, see the
