使脱机磁盘进入联机状态。Takes the offline disk to the online state. 对于基本磁盘,此命令尝试使所选磁盘和该磁盘上的所有卷联机。For basic disks, this command attempts to bring online the selected disk and all volumes on that disk. 对于动态磁盘,此命令会尝试将未标记为 "外部" 的所有磁盘都置于本地计算机上。For dynamic disks, this command attempts to bring online all disks that are not marked as foreign on the local computer. 它还尝试使动态磁盘集上的所有卷联机。It also attempts to bring online all volumes on the set of dynamic disks.

如果磁盘组中的动态磁盘处于联机状态,并且它是组中的唯一磁盘,则会重新创建原始组,并将磁盘移到该组。If a dynamic disk in a disk group is brought online and it's the only disk in the group, then the original group is recreated and the disk is moved to that group. 如果组中有其他磁盘并且它们处于联机状态,则磁盘只会重新添加到组中。If there are other disks in the group and they're online, then the disk is simply added back into the group. 如果选定磁盘的组包含镜像卷或 RAID-5 卷,此命令还会重新同步这些卷。If the group of a selected disk contains mirrored or RAID-5 volumes, this command also resynchronizes these volumes.
