Step 2: Check status of controllers and trays

You can the LEDs and the storage management software to check the status of your controllers and trays.

Procedure

  1. Look at the LEDs on controller A to make sure that it is booting correctly.

    The Host Link Service Action Required LEDs turn green during the reboot. The seven-segment display shows the sequence OS+ Sd+ blank- to indicate that the controller is performing Start-of-day (SOD) processing.

    After the controller successfully completes rebooting, the seven-segment display shows the tray ID matching the seven-segment display on the second controller. You can then discover the new controller canister by using the storage management software.

  2. If any of the controller-drive tray’s Service Action Required LEDs are on, or if the Controller Service Action Required LED is on:
    1. Check that the controller canister has been installed correctly and that all of the cables are correctly seated. Reinstall the controller canister, if necessary.
    2. Check the controller-drive tray’s Service Action Required LEDs and the Controller Service Action Required LED again. If the problem is not corrected, contact technical support.
  3. For a duplex configuration, repeat step 1 through step 2 for controller B.
  4. Using the LEDs and the storage management software, check the status of all of the trays in the storage array. If any component has a Needs Attention status, use the Recovery Guru to troubleshoot. If the problem is not resolved, contact technical support.
