Troubleshooting Cisco SAN-OS Software System Reboots
Recovering Both Supervisor Modules With Corrupted Bootflash
If both supervisor modules have corrupted bootflash, follow these steps:
Step 1 Boot the switch and press the Esc key after the BIOS memory test to interrupt the boot loader.
Note Press Esc immediately after you see the following message:
00000589K Low Memory Passed
00000000K Ext Memory Passed
Hit ^C if you want to run SETUP....
Wait.....
If you wait too long, you will skip the boot loader phase and enter the kickstart phase.
You se e t he
loader> prompt.
Caution The loader> prompt is different from the regular switch# or switch(boot)# prompt. The
CLI command completion feature does not work at this prompt and may result in undesired
errors. You must type the command exactly as you want the command to appear.
Tip Use the help command at the loader> prompt to display a list of commands available at this
prompt or to obtain more information about a specific command in that list.
Step 2 Specify the local IP address and the subnet mask for the switch.
loader> ip address 172.16.1.2 255.255.255.0
