Re: SRX300 reboots and get stucks in db mode when inserting USB Key
[ Edited ]
Please make sure that you are the right USB for it. Also, format a USB storage device in MS-DOS format.
On SRX300, SRX320, SRX340, SRX345, SRX380, and SRX550M devices, frequent plug and play of USB keys is not supported. You must wait for the device node creation before removing the USB key.
If an installation error occurs, the LEDs turn red, which might indicate that the Junos OS image on the USB flash drive is corrupted. An installation error can also occur if the current configuration on the SRX Series device is not compatible with the new Junos OS version on the USB or if there is not enough space on the SRX Series device to install the image. You must have console access to the SRX Series device to troubleshoot an installation error.
Also, do you have an "auto-snapshot" set in your system section of the SRX? It should automatically repair the primary partition when it boots to the secondary partition by overwriting it. Then the next time the box reboots it should try booting from the primary again.
Hope this helps 🙂
