The internal health LED identifies service events for internal components in a
pre-failure or failed condition. To identify status LED combinations for the
internal health LED and the system LEDs, see Appendix D,
“Troubleshooting.”
Hot-Plug SCSI Hard Drive LEDs
Each hot-plug SCSI hard drive has three LED indicators 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 attached to a
powered-on Smart Array Controller. Their behavior may vary depending on
the status of other drives in the array. Use Figure E-2 and Table E-2 to analyze
the status of each hot-plug SCSI hard drive.
WARNING: Before removing a hard drive, read the “Hot-plug Hard Drive
Replacement Guidelines” section in the Compaq Servers Troubleshooting Guide.
