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 4-6 in
conjunction with Table 4-7 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.
