While booting, the Security Analytics appliance is hung at a screen during the boot process that says, "Give root password for maintenance (or press Control-D) to continue). If you press Control-D, the server may continue to boot or it may reboot.
There is a file system inconsistency. Typically you will see a message on the boot screen complaining about a file system. You may see a message like "UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY". Pay attention to which volume it is complaining about. In the below example, the problem volume is /VAR
Security Analytics S500
Press Control+D to continue booting. If the server comes up, attempt to reboot again and see if it hangs at the same location. You may have to run a manual fsck, which can only be run if the partition is not mounted. You may need to boot into single user mode. Contact Broadcom support for assistance.
