282 Administering volumes
Enabling FastResync on a volume
NOTE: Simply moving volumes off of a disk, without also
removing the disk, does not prevent volumes from being moved
onto the disk by future operations. For example, using two
consecutive move operations may move volumes from the
second disk to the first.
Enter disk name [<disk>,list,q,?] mydg01
You can now optionally specify a list of disks to which the volume(s) should be
moved:
VxVM INFO V-5-2-516 You can now specify a list of disks to move
onto. Specify a list of disk media names (e.g., mydg01) all on
one line separated by blanks. If you do not enter any disk
media names, then the volumes will be moved to any available
space in the disk group.
At the prompt, press Return to move the volumes onto available space in the disk
group, or specify the disks in the disk group that should be used:
Enter disks [<disk ...>,list]
VxVM NOTICE V-5-2-283 Requested operation is to move all
volumes from disk mydg01 in group mydg.
NOTE: This operation can take a long time to complete.
Continue with operation? [y,n,q,?] (default: y)
As the volumes are moved from the disk, the vxdiskadm program displays the
status of the operation:
VxVM vxevac INFO V-5-2-24 Move volume voltest ...
When the volumes have all been moved, the vxdiskadm program displays the
following success message:
VxVM INFO V-5-2-188 Evacuation of disk mydg02 is complete.
3 At the following prompt, indicate whether you want to move volumes from another
disk (y) or return to the vxdiskadm main menu (n):
Move volumes from another disk? [y,n,q,?] (default: n)
Enabling FastResync on a volume
Note: The recommended method for enabling FastResync on a volume with a version 20
DCO is to use the
vxsnap prepare command as described in “Preparing a volume for
DRL and instant snapshots” on page 266.
You need a Veritas FlashSnap
TM
or FastResync license to use this feature.
FastResync performs quick and efficient resynchronization of stale mirrors. It also
increases the efficiency of the VxVM snapshot mechanism when used with operations
