Re: SRX 100 cli dead - /bin/csh: Input/output error

1. Plug a USB drive into a known healthy SRX which is of the same model and configuration as the faulty device. Run the following command:

>request system snapshot media usb

1. When the snapshot is complete, power down the faulty SRX. Remove the USB from the healthy SRX and plug it into the faulty SRX.


1. Power on the faulty device on and see if it will boot from the USB drive.


1. If it does, then snapshot the image from the USB drive back onto the compact flash (CF) with the following command:

>request system snapshot media internal
This will load the image from the USB onto the SRX's internal compact flash.

1. Then reboot the device from the compact flash. Use the following command:

>request system reboot media internal
Note: Taking a snapshot of the healthy device will also take a snapshot of the configuration, and will load the same configuration on the faulty device.
