Problem
EX device is complaining about errors which boil down to it complaining about being able to read/write to its disk.
The JTAC will usually ask you to do a format install of the switch before they will authorize a RMA, even though I've personally never seen this do anything other than waste time.
(Pro Tip: Tell the JTAC in your initial contact with them that you performed a format install and that the disk issues persisted after that.)
A "format" install has the switch reformat its disk partitions, in an effort to produce usable file systems for the installer.
As a side effect of this,
you will lose your configuration.
Solution
- make sure you have an installable copy of the running configuration
- connect a console
- reboot the device
- interrupt the boot process when it says
Press SPACE to abort autoboot
- enter the following, with appropriate substitutions (note that the gatewayip may not be necessary if you are on the same subnet as your tftp server)
- the switch will boot the new kernel, format the partitions, then install the firmware. On a EX2200 this took in excess of 40 minutes to run.
- the switch will reboot into Amnesiac state.
