Hot-Plug Hard Drive LEDs

This section provides the following information about hot-plug hard drive LEDs:

• An illustration detailing the location of each hot-plug hard drive LED

• A table of the possible LED configurations and what each combination means

The hot-plug SCSI hard drive LEDs, located on each physical drive, are visible on the front

of the server or external storage unit. They provide status information regarding drive

activity, connectivity, and fault status for each corresponding drive when configured as part

of an array and connected to an array controller. Their behavior may vary, depending on the

status of other drives in the array. Use Figure 4-7 with Tables 4-7 and 4-8 to analyze current

status for hot-plug hard drives that are connected to an array controller.

CAUTION: To avoid data loss, read “Hot-Plug Hard Drive Replacement Guidelines” in the

Compaq Servers Troubleshooting Guide before removing a hard drive.
