Understanding Hitless Upgrade—BlackDiamond 10K Switch Only
ExtremeWare XOS 11.1 Concepts Guide

Before the download begins, the switch prompts you to install the image immediately after the
download is finished. If you install the image immediately after download, the switch reboots.
●
If you download and install the software image on the active partition, you need to reboot the
switch. 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
y
to continue the installation and reboot the switch. Enter
n
to cancel.
●
If you install the image at a later time, use the following command to install the software:
install image <fname> {<partition>} {msm <slotid>} {reboot}
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 detailed information about modular software packages, see “Installing a Modular Software
Package” on page 420 . To perform a hitless upgrade, follow the steps described in the previous section,
“ Performing a Hitless Upgrade .”
Hitless Upgrade Examples
Using the assumptions described below, the following examples perform a hitless upgrade for a core
software image on the BlackDiamond 10K switch:
●
You have received the new software image from Extreme Networks named bd10K-11.1.0.14.xos .
●
You do not know your selected or booted partitions.
●
You are currently using the primary partition.
●
The image is on a TFTP server named tftphost .
●
You are installing the new image immediately after download.
●
The MSM installed in slot A is the primary.
●
The MSM installed in slot B is the backup.
●
You are running ExtremeWare XOS 11.1 or later on both MSMs.
Performing a hitless upgrade on the inactive partition (in this example, the secondary partition is the
inactive partition):
show switch
use image partition secondary msm B
download image tftphost bd10K-11.1.0.14.xos msm B
run msm-failover
download image tftphost bd10K-11.1.0.14.xos msm A
Performing a hitless upgrade on the current partition (in this example, the primary partition is the
current partition):
show switch
use image partition primary msm B
download image tftphost bd10K-11.1.0.14.xos msm B
run msm-failover
download image tftphost bd10K-11.1.0.14.xos msm A
