Important Guidelines About Replacing
Hot-Plug SCSI Hard Drives
NOTE
: For more information on interpreting hard drive LEDs, see Chapter 3,
“Server Operation.”
When replacing hot-plug hard drives, these guidelines must be followed:
■
Never remove a hot-plug drive if the LED is green. Replace a hot-
plug hard drive only when the drive’s LED is amber.
■
Never remove more than one drive at a time. When a drive is
replaced, the controller uses data from the other drives in the array to
reconstruct data on the replacement drive. If more than one drive is
removed, a complete data set is not available to reconstruct data on the
replacement drive(s).
■
Never remove a working drive when another drive has failed. Drives
that have been failed by the controller are indicated by the amber Drive
Failure LED on the drive tray. Permanent data loss will occur if a
working drive is removed when replacing a failed drive.
■
Never remove a drive while another drive is being rebuilt. A drive’s
Online LED will be flashing green whenever it is being rebuilt. A
replaced drive is restored from data stored on the other drives.
■
Never turn a ProLiant Storage System off while the server
controlling it is powered on. Doing so will cause the server's Smart
Controller to mark the drives as "failed." This could result in permanent
data loss.
■
If an online spare drive is installed, wait for it to complete
rebuilding before replacing the failed drive. When a drive fails, the
online spare will become active and begin being rebuilt as a replacement
drive. After the online spare has been completely rebuilt (Online LED
will be solid green), the failed drive should be replaced with a new
replacement drive. Do not replace the failed drive with the online spare.
