Installing Hardware Options 4-23 Important Guidelines About Replacing Hot-Plug SCSI Hard Drives When replacing hot-plug hard drives in a fault-tolerant configuration, these guidelines must be followed: s Never remove a hot-plug drive if the Online LED is green. Replace a hot-plug hard drive only when the drive's Fault LED is amber, indicating a failure. s 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). 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. s 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. s 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. s 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. s A POST error message will occur when the system is turned on if a drive(s) has been replaced while the system is OFF. When this occurs you will be prompted to: PRESS TO BOOT THE SYSTEM AND REBUILD THE REPLACED DRIVE , OR PRESS TO BOOT THE SYSTEM AND NOT REBUILD THE DRIVE(S). CAUTION: Pressing F2 will cause permanent data loss to the entire logical drive. F2 should be pressed only if all of the drives have been replaced or if complete data loss is desired.

Important Guidelines About Replacing Hot-Plug
SCSI Hard Drives
When replacing hot-plug hard drives in a fault-tolerant configuration, these
guidelines must be followed:
■
Never remove a hot-plug drive if the Online LED is green
. Replace a
hot-plug hard drive only when the drive’s Fault LED is amber,
indicating a failure.
■
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.
■
A POST error message will occur when the system is turned on if a
drive(s) has been replaced while the system is OFF.
When this occurs
you will be prompted to:
PRESS <F1> TO BOOT THE SYSTEM AND REBUILD THE REPLACED DRIVE , OR
PRESS <F2> TO BOOT THE SYSTEM AND NOT REBUILD THE DRIVE(S).
CAUTION:
Pressing
F2
will cause permanent data loss to the entire logical
drive.
F2
should be pressed only if all of the drives have been replaced or if
complete data loss is desired.
