Powering down the compute module

Before powering down the compute module for any upgrade or maintenance procedures, perform a backup of the system and all data. Then, shut down, as appropriate, applications and operating systems. A successful shutdown is indicated by the system power LED displaying amber.

IMPORTANT:

Always attempt a graceful shutdown before forcing a nongraceful shutdown. Application data can be lost when performing a nongraceful shutdown of applications and the OS.

Before proceeding, verify the following:

  • The compute module is in standby mode by observing that the system power LED is amber.

  • The UID LED is not flashing blue.

    NOTE:
    • When the compute module is in standby mode, auxiliary power is still being provided to the system.
    • If the UID LED is flashing blue, a remote session, or a firmware update is in progress.

To power down the compute module, use one of the following methods:

  • To perform a graceful shutdown of applications and the OS when powering down the compute module to standby mode, do one of the following:
    • Press and release the Power On/Standby button.
    • Select the Momentary press power off selection in HPE OneView.
    • Select the Momentary press virtual power button selection in HPE iLO.
  • If a graceful shutdown fails to power down the compute module to standby mode when an application or OS stops responding, force a nongraceful shutdown of applications and the OS. Do one of the following:
    • Press and hold the Power On/Standby button for more than four seconds.
    • Select the Press and hold power off selection in HPE OneView.
    • Select the Press and hold virtual power button selection in HPE iLO.
