Troubleshooting Cisco SAN-OS Software Upgrades and Downgrades

Note

Before exiting the session, be sure that the upgrade process is complete. The wizard displays 
status messages as the upgrade proceeds. Check the lower left-hand corner of the wizard for the 
status messages. First, the wizard displays the message

 

Success

 

followed a few seconds later 

by 

InProgress Polling

. Then the wizard displays a second message 

Success

 

before displaying 

the final 

Upgrade Finished

.

Installing Cisco SAN-OS Software from the CLI

To perform an automated software upgrade on any switch from the CLI, follow these steps:

Step 1

Log into the switch through the console, Telnet, or SSH port of the active supervisor. 

Step 2

Create a backup of your existing configuration file, if required.

Step 3

Perform the upgrade by issuing the

 install all

 command.

The example below demonstrates upgrading from SAN-OS 2.0(2b) to 2.1(1a) using the 

install all

 

command with the source images located on a SCP server.

Tip

Always carefully read the output of 

install all 

compatibility check. This compatibility check 

tells you exactly what needs to be upgraded (BIOS, loader, firmware) and what modules are not 
hitless. If there are any questions or concerns about the results of the output, select 

n 

to stop the 

installation and contact the next level of support.
