System Hangs During Boot
After attaching the system console cable, if the system hangs during boot, try booting with the –i
option as described in the previous section. It is possible that important Linux system files
became corrupted and incorrectly saved in the flash overlay. Use zmnt as described in the
previous section to fix or remove the problem files from the overlay. If the system will not boot
with the –i option, refer to Booting the Duplicate Flash Image section in this chapter.
Booting the Duplicate Flash Image
Another recovery method, if Linux fails to boot, is to temporarily boot the factory-installed
duplicate image located in the second flash device.
Connect through the console port.
When you see the number counter appear after the zmonitor ... banner, press any key on the
console keyboard to enter the zmon application.
At the monitor prompt, type:
boot:2
You should see the counter again, but the system should boot into the secondary kernel. If you
have difficulties booting, contact Hewlett-Packard technical support.
At this point, follow the Upgrading the OpenArchitect Image section to put a new RAM disk
image in the application flash 1.
The command to program flash 1 should be similar to the following command. The image name
may be slightly different depending on the model of switch and version of the image:
zflash –d 1 rdr7100.zImage.initrd
Upgrading the OpenArchitect Image
Use telnet, or preferably, attach a console cable to the switch, and login to the switch. If you
are connecting via telnet, be aware that the upgrade process will reset the switch to the default
IP address of 10.0.0.43, so you will have to be able to reach 10.0.0.43.

IMPORTANT: Be sure not to program flash 2, since currently this is your only
bootable image.
