Moving Objects Between Dynamic Disk Groups

68 VERITAS Volume Manager User’s Guide - VEA

Notes:

◆ Before moving volumes between dynamic disk groups, stop all applications that are

accessing the volumes, and unmount all ﬁle systems that are conﬁgured in the volumes.

◆ The objects to be moved must be self-contained, meaning that the disks that are moved

must not contain any other objects that are not intended for the move.

◆ This operation fails if it would remove all the disks from the source dynamic disk group.

◆ Volume states are preserved across the move.

◆ The reconﬁguration must involve an integral number of physical disks.

◆ Objects to be moved must not contain open volumes.

◆ Data change objects (DCOs) and snap objects that have been dissociated by Persistent

FastResync cannot be moved between dynamic disk groups.

◆ If your system supports VERITAS Volume Replicator (VVR), then it should be noted that

VVR objects cannot be moved between dynamic disk groups.

◆ For a dynamic disk group move to succeed, the source dynamic disk group must contain

at least one disk that can store copies of the conﬁguration database after the move.

◆ For a dynamic disk group move to succeed, the conﬁguration database in the target

dynamic diskgroup must be ableto accommodate informationabout all theobjects in the

enlarged dynamic disk group.

◆ The operation can only be performed on the master node of a cluster if either the source

dynamic disk group or the target dynamic disk group is shared.
