Enabling automatic boot file updating
CAUTION:
•
After automatically loading the master’s boot file, a subordinate switch configures the file as the boot
file to be used at the next boot and reboots automatically.
•
To ensure a successful auto upgrade, check that the storage device of the subordinate switch has
sufficient space.
If you want to upgrade the BootROM (see the release notes for detailed requirements) when you
upgrade the boot file, follow these steps to upgrade the BootROM:
1.
Upload the software version file to be used to the master, and then use the
bootrom upgrade
command to upgrade the BootROM of the master.
2.
Use the
boot-loader
command with the
slot
all
keywords to specify the software version file as the
boot file to be used at the next reboot and apply this configuration on all member switches.
3.
Reboot the all member switches in the IRF virtual device to complete the software upgrade process.
When you add a switch to the IRF virtual device, the automatic boot file updating function compares the
software versions of the switch and the IRF master. If the versions are different, the switch automatically
downloads the boot file from the master, sets the downloaded file as the boot file for the next reboot,
and automatically reboots with the new boot file to re-join the IRF virtual device.
If automatic upgrade of boot file is enabled, as soon as a switch is added into an IRF virtual device, the
IRF virtual device compares its software version with that of the master. If the versions are not consistent,
the switch automatically downloads the boot file from the master, reboots with the new boot file, and
joins the IRF virtual device again. If the downloaded boot file and the local boot file have duplicate file
names, the local file is overwritten.
