I have been busy last sunday with the replacement of a Brocade switch, to be specific an HP branded 4/24 in a c7000 blade enclosure. After searching both the HP and Brocade website I haven’t found any clear documentation about replace a switch in a fabric.
So I just decided to try something out to see of my ideas were correct about how to replace a switch. The procedure I came up with and which seems to work is the following:
- Make sure your replacement switch has the same licenses as the original switch. If not, contact Brocade or the OEM vendor, in my case HP, for a license move of your licenses to the replacement switch
- Do not connect your replacement switch to the fabric yet, but connect it to your network and, if neeeded, give an IP-address.
- Be sure to have a saved configuration of the original switch ready. Regularly schedule a backup with ‘configupload’ to save it.
- Know the firmware version of the switch which is to be replaced and make sure your replacement switch has the exact same firmware version.
- Change the default passwords of the replacement switch
- Disable your switch with ‘switchdisable’. The reason for this is that it needs to be disabled to do the next step.
- ‘configdownload’ the configuration of the original switch to your replacement switch and reboot the replacement switch
- In my case the ‘configdownload’ didn’t apply the switchname and DNS settings in the configuration to the replacement switch so I configured these two.
- Verify the configuration in the replacement switch, check the settings. Most importantly the configuration setting e.g. domain id
- Clear the complete zoning configuration with ‘cfgdisable’, ‘cfgclear’ and ‘cfgsave’. Verify this step 🙂 !
- Now it’s time to connect it to the fabric and to your hosts and storage array’s
- Voilá, everything should be okay now
This list seemed to be okay for the situation I replaced the switch in. It consisted in total of 10 switches and one HP MPX200 router.
Please leave comments if this didn’t work out for you or if you think I forgot some steps…
