Description: Describes the type of reboot that occurred the last time the host device rebooted.
Unknown(0), unknown reboot. 0 is used as a sentinel value to denote that the reboot reporting mechanism is initialized and ready for use. If it appears in a reboot report as a reboot reason, it means that something (of unknown cause) prevented a reboot reason from being saved. This is a spontaneous reboot.
Davic/DOCSIS(1), Davic/DOCSIS switch. The set-top rebooted because the network switched from Davic to DOCSIS or vice versa. This is a controlled reboot.
User(2), User reboot. The set-top rebooted at the specific request of the user, typically the MSO, but can also be the subscriber. Includes, but not limited to, headend-initiated reboots, pass-thru and SNMP messages to reboot, new application versions that require a reboot in order to reload, the staging toolkit, hard disk re-format requests, CableCARD inserted or firmware upgrade, and more. This is a controlled reboot.
System(3), System reboot. The set-top rebooted because its software determined it cannot continue operation. This can be due to any number of reasons, including: detection of logic errors, exhaustion of various system resources, detection of memory corruption, and more. This is a spontaneous reboot.
Trap(4), Trap reboot. A fatal error detected by the CPU. This varies between CPU manufacturers; some possible causes are illegal address references, misaligned instruction or data access, memory protection violations, attempt to decode an unrecognized instruction, etc. This is a spontaneous reboot.
Silent or Watchdog(5). Depending on platform, this is either a Silent Reboot (A reboot of unknown origin that reports no information) or a Watchdog reboot. This is a spontaneous reboot.
Bootloader(6), Bootloader reboot. For use by bootloader software. This is a spontaneous reboot.
PowerUp(7), Power-up reboot. The set-top rebooted because power was lost and then restored. This is a controlled reboot.
Upgrade(8), Upgrade Reboot due to loading new resident set-top software. This is a controlled reboot.
Hardware(9), Hardware Reset reboot. This depends on the design of a particular set-top. It might be due to a hardware reset line being triggered or by a button push of some kind. Manufacturers sometimes provide a way to hard reset a box besides removing power. This is a spontaneous reboot.
CablecardError(10), CablecardError. The Host rebooted because the communication with the CableCARD was lost and could not be reestablished.
What is ocStbHostRebootType?
Reports the reason for the Host's most recent reboot, e.g. hardware(9) for a manual hardware reset, cablecardError(10) if communication with the CableCARD was lost and never reestablished, or unknown(0), a sentinel meaning the reboot's actual cause wasn't captured; distinguishing a controlled reboot (like user(2) or powerup(7)) from a spontaneous one (like system(3) or trap(4)) helps an operator tell a deliberate action from an unexpected fault.
