Important Guidelines for Replacing
Hot-Pluggable Hard Drives
Follow these guidelines when replacing drives:
n 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) and permanent data loss could occur.
n Never remove a working drive.
Drives that have been failed by the controller are indicated by the amber
Drive Failure LED on the drive carrier. Permanent data loss will occur if a
working drive is removed while replacing a failed drive. See Figure 1.
n Never remove a drive while another drive is being rebuilt.
A drive’s Online LED will be flashing green while it is being rebuilt. A
replaced drive is rebuilt from data stored on the other drives. See Figure 1.
n Never turn a disk enclosure off while the initiator or controller is powered
on or active.
Doing so may cause the initiator or controller to mark the drives as “failed.”
This could result in permanent data loss.
n If the system has an online spare drive, 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 completed Automatic
Data Recovery (The Online LED will be continuously lit), the failed drive
should be replaced with a new replacement drive. Do not replace the failed
drive with the online spare. See Figure 1.
n If a drive is replaced while the system is Off, it may be necessary to rebuild
the replaced drive.
Follow the instructions on the screen or the instructions outlined in the
system's reference guide.

1 Press the ejector button of the hard drive.
2 Pivot the lever into the full open position.
