Hot-Plug Hard Drive LEDs

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 (1), connectivity (2), and fault (3) 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 the illustration in Figure 4-6in conjunction with Table 4-7to 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.
