|Applies To||RSA Product Set: RSA NetWitness Platform|
RSA Product/Service Type: Core Appliance
RSA Version/Condition: 11.4.x
Platform (Other): NetWitness Series 4S appliance
O/S Version: 7
|Issue||After NetWitness upgrade to 11.4.x and rebooting the appliance to complete the upgrade, the appliance does not come back online.|
The appliance console shows that the boot has failed with error "Dependency failed for /boot" and the boot stops at maintenance mode login.
|Cause||Some NetWitness Series 4S appliances were shipped using the internal SD cards as the boot partition.|
NetWitness 11.4.x includes an additional security configuration which disables USB storage, like the SD card, so the new OS cannot mount the /boot partition.
|Resolution||To fix this at the emergency mode prompt, login with the root password.|
If the known root password doesn't work then try the default password, netwitness
In the /etc/modprobe.d/ directory look for the file, disable-usb-storage.conf, move or remove the file, and then reboot the appliance.
mv /etc/modprobe.d/disable-usb-storage.conf /root/disable-usb-storage.conf
The OS should now be able to see the SD card and boot with the new kernel version.
|Workaround||Another temporary work-around is to boot the appliance with the old kernel.|
Reboot the appliance and monitor the appliance console for the appearance of the Grub Menu.
Press the down arrow key to select the previous kernel version and then press Enter.
|Notes||This fix might get reversed with the next kernel update in a future NetWitness version upgrade.|
It is highly recommended to rebuild the appliance with the SD cards disabled.
