Status Description

PWR

Power button/indicator

Yellow and green

  • Off: The compute node is not powered on.
  • Blinking yellow: The power button on the compute node is locked.

    When iMana 200 is being started during the compute node power-on process, the power button is locked.

  • Steady yellow: The compute node is to be powered on.
  • Steady green: The compute node is properly powered on.
NOTE:
  • When the server is powered on, pressing this button will shut down the OS properly or cause the server to become unresponsive.
  • When the server is powered on, holding down this button for 6 seconds will power off the server.
  • When the server is in the standby state, pressing this button will power on the server.

UID

UID button/indicator

Blue

The Unit Identification (UID) indicator helps locate a compute node in a chassis. You can control the UID indicator status (off, on, or blinking) by remotely using the MM910.

  • Off: The compute node is not located or is not powered on.
  • On: The compute node is located.
  • Blinking: The compute node is being located.
NOTE:
  • You can press this button to turn on or off the UID indicator.
  • You can hold down the UID button for 4 to 6 seconds to reset iMana 200.

HLY

Health status indicator

Red and green

  • Off: The compute node is not powered on.
  • Steady green: The compute node hardware is operating properly.
  • Blinking red (at 1 Hz): A major alarm is generated for the compute node.
  • Blinking red (at 5 Hz): A critical alarm is generated for the compute node, or the compute node is not securely installed.

Hard disk active indicator

Green

  • Off: The hard disk is not detected or is faulty.
  • Blinking green: Data is being read from or written to the hard disk.
  • Steady green: The hard disk is inactive.

Hard disk fault indicator

Yellow

  • Off: The hard disk is operating properly.
  • Blinking yellow: The hard disk is being located, or RAID is being rebuilt.
  • Steady yellow: The hard disk is not detected or is faulty.

0-14

Hard disk status indicator of dual colors

Red or green

The indicator is on the front panel and has the following status:

  • Off: The hard disk is not installed or in a RAID.
  • Steady green: The hard disk is installed, but no data is being read from or written to the hard disk.
  • Blinking green (at 4 Hz): (1) The hard disk is reading or writing data properly. (2) The primary hard disk (or hot spare disk) is synchronizing data to the secondary hard disk. This indicator status is described for the primary hard disk (or hot spare disk).
  • Blinking green (at 1 Hz): (1) The secondary hard disk is synchronizing data from the primary hard disk (or hot spare disk). This indicator status is described for the secondary hard disk. (2) The hard disk is faulty, and the hot spare disk is synchronizing data from the faulty hard disk. This indicator status is described for the hot spare disk.
  • Blinking red (at 1 Hz): The hard disk is being located and stops transferring data.
  • Blinking red (at 4 Hz): (1) The hard disk in a RAID is removed. (2) The hard disk is faulty and is synchronizing data to the hot spare disk.
  • Steady red: The hard disk is faulty.

DRW

TEMP

Hard disk drawer indicator

Yellow

  • Off: The hard disk drawer is completely closed.
  • Steady yellow: The hard disk drawer is pulled out.
