You can the LEDs and the storage management software to check the status of your controllers and trays.
Procedure
- 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.
- If any of the controller-drive tray’s Service Action Required LEDs are on, or if the Controller Service Action Required LED is on:
- Check that the controller canister has been installed correctly and that all of the cables are correctly seated. Reinstall the controller canister, if necessary.
- 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.
- For a duplex configuration, repeat step 1 through step 2 for controller B.
- 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.
