The reset may take several minutes to complete. After the server has been reset, the Overall Status field on
the General tab displays an ok status.
Avoiding Unexpected Server Power Changes
If a server is not associated with a service profile, you can use any available means to change the server power
state, including the physical Power or Reset buttons on the server.
If a server is associated with, or assigned to, a service profile, you should only use the following methods to
change the server power state:
• In Cisco UCS Manager GUI, go to the General tab for the server or the service profile associated with
the server and select Boot Server or Shutdown Server from the Actions area.
• In Cisco UCS Manager CLI, scope to the server or the service profile associated with the server and use
the power up or power down commands.
Do not use any of the following options on an associated server that is currently powered off:
Important
• Reset in the GUI
• cycle cycle-immediate or reset hard-reset-immediate in the CLI
• The physical Power or Reset buttons on the server
If you reset, cycle, or use the physical power buttons on a server that is currently powered off, the server's
actual power state may become out of sync with the desired power state setting in the service profile. If the
communication between the server and Cisco UCS Manager is disrupted or if the service profile configuration
changes, Cisco UCS Manager may apply the desired power state from the service profile to the server, causing
an unexpected power change.
In Cisco UCS release 2.0.1, power synchronization issues can lead to unexpected server shut downs or restarts
