Splitting A Dynamic Disk Group

70 VERITAS Volume Manager User’s Guide - VEA

Notes:

◆ Before carrying out the split operation, stop all applications that are accessing the

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

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

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 split.

◆ An existing deported dynamic disk group is destroyed if it has the same name as the

target dynamic disk group.

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

◆ Objects to be split off 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 VVR, then it should be noted that VVR objects cannot be moved

between dynamic disk groups.
