◊
Ensure that all power cords are firmly plugged into the proper
receptacles.
•
If the system is plugged into a switched, multiple-outlet box, make sure
the switch on the outlet box is turned to the on position.
•
If the power supply still does not power up, it may be defective. Remove
and replace it with a different power supply.
•
Shut down the system and exchange the faulty unit with the other unit.
Restart the system and check both power supplies.

Hard Drives Not Responding

•
If the OS Event Log displays device timeouts, one or more hard drives
cannot access the SCSI channel due to high system or disk activity.
Device timeouts may occur in a simplex configuration of 12 hard drives. If
timeouts occur frequently, the recommended solution is to add a second
RS/12 SCSI card and connect to the host through a duplex configuration.
•
If the Drive Power Indication is not lit, check the following:
◊
Check to make sure that the HP Rack Storage/12 is powered on and
the there is power to the unit.
◊
Check that the hard drive is seated in the drive cage. Remove and
reinstall the hard drive. If the hard drive still does not spin up, replace
it with another hard drive.
•
If the Drive Activity Indicator displays green for more than one minute,
the hard drive is either spinning up or has "hung." Check the drive status
through your RAID management application.
•
If the Drive Activity Indicator is flashing yellow, the hard drive is
predicting a failure. Replace it with a new hard drive.
•
If the Drive Activity Indicator is red, the hard drive has been marked
offline or has failed. Replace it with a new hard drive.
