CAUTION:

When replacing a hot pluggable hard drive, it is importantthatyoufollowtheguidelinesinthissection.

Failure to do so could result in data loss and could void your warranty.

Removing the hard drive

Follow these guidelines when replacing hard drives:

• Never remove more than one hard drive at a time (two if using RAID 6). When you replace a hard

drive, the controller uses data from the other hard drives in the array to reconstruct data on the

replacement hard drive. If you remove more than one hard drive, a complete data set is not available

to reconstruct data on the replacement drive(s) and permanent data loss could occur.

• Never remove a working hard drive. The amber Drive Failure LED indicates a hard drive that has

been failed by the controller. Permanent data loss will occur if a working hard drive is removed

while replacing a failed drive.

• Neverremoveaharddrivewhileanotherharddriveisbeingrebuilt. Adrive'sOnlineLEDsﬂash

green (once per second) while it is being rebuilt. A replaced hard drive is rebuilt from data stored on

the other hard drives.

• If the system has an online spare drive, wait for it to complete rebuilding before replacing the

failed drive. When a hard drive fails, the online spare becomes active and begins rebuilding as a

replacement drive. After the online spare has completed Automatic Data Recovery (the online LEDs

will be continuously lit), replace the failed hard drive with a new replacement drive. Do not replace

the failed hard drive with the online spare. The system will automatically rebuild the replacement

hard drive and reset the spare hard drive to an available state.

• If you replace a hard drive while the system is off, it may be necessary to rebuild the replaced

hard drive.

NOTE:

Illustrations in this section demonstrate removing a hard drive from an MSA20 storage enclosure. The

procedure for removing a hard drive blank from an MSA30 or other storage enclosure is similar.

1. Review all warnings, cautions, and preparation procedures as detailed in the MSA1510i

Maintenance and service guide.

2. Be sure that the Online and Drive Access LEDs are both off and that the Fault LED is on.

3. Press the ejector button (1) and pull the release lever to the full open position (2).

IMPORTANT:

Wait approximately 10 seconds for the internal disk to stop spinning before pulling the

hard drive out of the enclosure. Handling a hard drive while the internal media is spinning

can damage the media.
