Hard Drive Problems
Use this section to troubleshoot hard drive problems. For more troubleshooting
tips, also see “SCSI Device Problems” later in this appendix.
IMPORTANT:
If the hard drive Fault LED is on, follow the proper troubleshooting
procedures, find the cause of the problem and fix it. One common mistake with failed
hot-plug drives in a fault tolerant array is hot-plugging (removing the drive for a few
seconds and reseating the same drive) without fixing the cause. Hot-plugging often
causes the Fault LED to turn off, but does not solve the problem that caused it to light
initially. Usually the drive needs replacing, but in some situations a problem could exist
with the drive cage, the SCSI cable, or the controller.
Each hot-plug SCSI hard drive has three LEDs located on the front of the
drive. The LEDs provide activity, online, and fault status for each
corresponding drive when configured as a part of an array and connected to a
powered-up Smart Array Controller. The LED behavior can vary, depending
on the status of other drives in the array. Refer to your server-specific user
documentation for specific information about drive statuses.
WARNING:
To reduce the risk of personal injury and damage to the equipment,
read the “Hot-Plug Hard Drive Replacement Guidelines” in the next section of
this appendix before removing a hard drive.
For more information on individual drive specifications, refer to your
server-specific user documentation, the maintenance and service guide, the
drive documentation, and the array controller documentation.
