8.2.1 Do Not Service LED on Storage Servers

Powering off an Oracle Exadata Storage Server in a cluster with reduced redundancy may cause Oracle ASM disk group force dismount and compromise data availability. To prevent human errors such as mistakenly powering off the wrong storage server, on Oracle Exadata Database Machine X7 come with a new Do Not Service LED. This LED indicates whether it is safe to power off the Oracle Exadata Storage Server for services. Starting with Oracle Exadata System Software release 18.1, the Do Not Service LED is turned on automatically in real-time when redundancy is reduced to inform system administrators or field engineers that the storage server should not be powered off for services.

For example, if a storage server or disk is offline, Oracle Exadata System Software automatically turns on the Do Not Service LED on the storage servers that contain the partner disks to indicate these servers should not be turned off for servicing. When redundancy is restored, Oracle Exadata System Software automatically turns off the Do Not Service LED to indicate that the storage server can be powered off for servicing.
