Upgrading OS on Cisco SAN switch

To upgrade IOS on Cisco SAN switch use following steps (Tested on MDS9148S):

1. Open Device Manager in browser after configuring IP address
2. Download latest iOS and corresponding kickstart file from Cisco site
3. From Device Manager go to Admin -> Licenses. Use the copy option to copy files from a Linux machine using scp.
4. Install new OS using:

   install all kickstart m9100-s5ek9-kickstart-mz.7.3.0.DY.1.bin system m9100-s5ek9-mz.7.3.0.DY.1.bin
   #Takes long time for many checks.  Do not press Enter as after checking it will ask (y/n) and pressing enter will cause installation to stop

5. Switch automatically reboots. New OS should now be working.
6. 'show version' to check new version. Optionally do 'show boot' to check boot configuration
