If the switch still is unable to boot, see Booting the Duplicate Flash Image, below.
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.
1. Connect through the console port.
2. When you see the number counter appear after the zmonitor ... banner, press any key
on the console keyboard to enter the zmon application.
3. At the monitor prompt, type: boot:2
4. 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.
5. At this point, follow the Upgrading the OpenArchitect Image section to put a new RAM
disk image in the application flash 1.
IMORTANT: Do not program flash 2, since this is currently your only bootable
image. 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.
Base Interface: zflash -d 1 rdr6000.zImage.initrd
Fabric Interface: zflash –d 1 rdr7100.zImage.initrd
NOTE: If the duplicate flash image cannot be loaded, remove and return switch for
repair.
