Task at Hand
Upgrade Cisco MDS (9706 specifically in my case)
Personal Blurb
I decided it was high time to upgrade our MDS 9706's to the Cisco recommended code, so I set out on the, at first glance, daunting task of upgrading our MDSes.
Prep (Very Important!)
Validate that each of your Hosts is Dual Legged so that if you need to reboot each side of the SAN that they will not lose connection to their storage.
Let's get to Work!
- Download the Target Code from Cisco's website (This requires that you have a Cisco Account)
- Use a TFTP Server to move the firmware over to the MDS Switches (I used tftpd)
- Location to Transfer to on the Switch: bootflash:
- Copy Commands
- copy tftp://<tftpd_server>/mdsfirmware/<Firmware_bin_file> bootflash:<firmware_bin_file>
- copy tftp://<tftpd server>/mdsfirmware/<firmware_bin_file> bootflash:<firmware_bin_file>
- Save your current MDS config files off to a safe location (We use Solarwinds)
- Install Firmware on Switch A
- Install Command
- install all kickstart bootflash:<firmware_bin_file_from_step_2> system bootflash:<firmware_bin_file_from_step_2>
- Validate the Install was successful on Switch A
- show module
- This should show the new version was installed
- Wait 30 Minutes (You could probably do a shorter time frame, but this is my safety net)
- Repeat Steps 2 thru 5 on Switch B
