Extreme Networks ExtremeWare XOS Command Reference Manual page 1905

ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
Hitless upgrade support for the BlackDiamond 8800 series switch and the BlackDiamond 12804 switch was
introduced in ExtremeWare XOS 11.4.
You must have two MSMs installed in your switch to perform a hitless upgrade. With two MSMs
installed in the switch, one assumes the role of primary and the other assumes the role of backup. The
primary MSM provides all of the switch management functions including bringing up and
programming the I/O modules, running the bridging and routing protocols, and configuring the switch.
The primary MSM also synchronizes its configurations with the backup MSM which allows the backup
to take over the management functions of the primary.
NOTE
If you download an image to the backup MSM, the image passes through the primary MSM before the image is
downloaded to the backup MSM.
1 View current switch information using the following command:
show switch
Determine your selected and booted partition, verify which MSM is the primary and which is the
backup, and confirm that the MSMs are synchronized.
Output from this command indicates, for each MSM, the selected and booted images and if they are
in the primary or the secondary partition. The selected image partition indicates which image will be
used at the next reboot. The booted image partition indicates the image used at the last reboot. It is
the active partition.
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).
2 Select the partition to download the image to and download and install the new ExtremeWare XOS
software on the backup MSM using the following command:
download image [[<hostname> | <ipaddress>] <filename> {{vr} <vrname>} | memorycard
<filename>] {<partition>} {msm <slotid>}
NOTE
If the backup MSM is installed in slot B, specify msm B. If the backup MSM is installed in slot A, specify msm
A.
Before the download begins, the switch asks if you want to install the image immediately after the
download is finished. If you download and install the image immediately to the active partition, the
switch automatically reboots the MSM.
If you download and install the software image on the active partition, the switch automatically
●
reboots the MSM after the image is installed. The following message appears when downloading
and installing on the active partition:
Image will be installed to the active partition, a reboot required. Do you
want to continue? (y or n)
Enter to continue the installation and reboot the switch. Enter
y
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}
