dynamie disks fail. For example, because volumes can span multiple disks by

using simple disk spanning and striping redundancy mechanisms, the display

status of a volume in the Import Foreign Disks dialog box can become

complicated if not all of the disks have been moved.

Another complication can occur when you move a disk and then later move

additional disks. For example, if you move one active mirror of a volume from

one system to another, and then you move another later, one of the two mirrors

appears to be up-to-date on one system, and the other mirror appears up-to-date

on the other system. When the two mirrors are put together on the same system,

they both appear up-to-date, but they have different contents. For this reason, it

is recommended that you move all fault-tolerant and non-fault-tolerant volumes

that span disks at the same time.

For morę information about fault-tolerant disks, such as RAID-5 and

mirrored disks, see Appendix E, . Managing Fault-Tolerant Disks,. on the

Student Materials compact disc.

Groups of disks that you move from one Computer to another are grouped

according to the Computer from which they were moved. Disk Management

displays the groups of moved disks as foreign disks. If you move one or morę

disks from a disk group to another Computer that contains its own disk group,

the disk group that you move is considered as Foreign until you import it into
