User Guide217www.nec-computers.comNote: While hard disks are in the disk array configuration(RAID1 or RAID5), a single failed hard disk does not affect theoperation of the server. However, it is recommended to replacethe failed hard disk and auto-rebuild (reconfigure) the harddisks as soon as possible. (You can hot-swap such a failed harddisk.)■ Blinking alternately green or amber- Indicates that the hard disk is being rebuilt (this status is not a failure). If thedefective hard disk is replaced with a new one in the disk array configuration,the data is automatically rebuilt (auto rebuild function). During the rebuild oper-ation, the lamp is lit green or amber alternately.- The lamp goes off when the rebuild is terminated normally. The lamp goes onamber if the rebuild fails.Note: To abort rebuilding, power off the server. In such acase, restart the server, hot-swap the failed hard disk, andrestart rebuilding. Observe the following notes to use the auto-rebuild feature.Caution■ Do not power off the server. (If the server is powered offbefore rebuilding hard disks, the auto-rebuild feature will notstart.)■ When you removed a hard disk, wait at least 90 secondsbefore installing the hard disk back again.■ Do not replace another hard disk while rebuilding is inprogress.
