Function: Recovery Mode: Service Usage: Technical Service Description This command is used in a variety of SP or system shutdown procedures, or during triage to determine which system component is responsible for the SP booting into Service Mode. The procedures are: ● List-this option details why the current SP has booted into Service Mode. ● Set-this option manually forces the SP to boot into Service Mode the next time it is rebooted. ● Clear-this option resets all the boot control counters and instructs the SP to attempt to boot into Normal Mode on the next reboot. Note that errors or faults can still cause the system to boot back into Service Mode. In most instances, you must first address the failure condition which put the SP into service mode before proceeding with clearing the counters. ● Clear Degraded-this option resets all of the degraded mode indicators stored in both the nvram and on the local SSD boot device. Only use this option to clear Degrade Mode conditions if the reason the system is in service mode was due to an 'rrchc' code in the Rescue Reason of svc_diag that indicates that: 1. A driver on the system has decided to put the SP or system in 'degraded' mode. 2. The fault that landed the system and driver into a 'degraded' state has been cleared or fixed locally in service mode. As with the Clear option, errors or faults can still cause the system to boot back into Service Mode. ● (virtual deployments only)Tie-breaker node (TBN) options: ○ Ignore TBN once-this option sets a flag file for the UnityVSA SP to have the SP ignore TBN status the next time system boots up.

This command is used in a variety of SP or system shutdown procedures, or during triage to determine which system
component is responsible for the SP booting into Service Mode. The procedures are:
●
List—this option details why the current SP has booted into Service Mode.
●
Set—this option manually forces the SP to boot into Service Mode the next time it is rebooted.
●
Clear—this option resets all the boot control counters and instructs the SP to attempt to boot into Normal Mode on the

must first address the failure condition which put the SP into service mode before proceeding with clearing the counters.
●
Clear Degraded—this option resets all of the degraded mode indicators stored in both the nvram and on the local SSD boot

1.
A driver on the system has decided to put the SP or system in 'degraded' mode.
2.
