Creating migration groups
A migration group defines a source element for migration and the migration task that will run on the
source element. A source element can be either a virtual disk or a VDG.
Creating migration groups on virtual disks
NOTE:
For migration groups created on virtual disks, the destination virtual disk is assigned the OpenVMS
Unit ID (OUID) of the original source virtual disk and the source virtual disk is assigned the default
OUID of 0 upon completion of the migration. There is no change in assignment during the migration.
In order to support the creation of a migration group, a virtual disk must fulfill the following conditions:
• The virtual disk status must be Normal.
• The virtual disk must not belong to a VDG.
• The virtual disk must not be a temporary virtual disk.
• The virtual disk must not be presented to a VSM server.
• The virtual disk must not be a SAN API virtual disk.
• Conditions must be such that a PiT can be created on the virtual disk.
• The virtual disk must not be the setup virtual disk for the domain.
• No other snapclone, migration, or mirror tasks can be running currently on the virtual disk.
• If the virtual disk has PiTs, there must be no snapshot on any of the PiTs.
To create a migration group on a virtual disk:
1. Do one of the following:
a. Right-click the virtual disk that you want to migrate.
b. Select Manage > Migration Service > Create Migration. The Create Migration wizard opens
to the Enter Migration Group parameters screen.
or
a. Right-click the Migration Groups node.
b. Select New > On Virtual Disk. The Create Migration Group wizard opens to the Enter Migration
Group parameters screen.
2. In the Group name field, enter a name for the group.
3. In the Task name field, enter a name for the task that will be run on the group.
4. In the Auxiliary name field, enter the name that will be used initially for the destination virtual
disk and will become the name of the virtual disk on the source storage pool when the task
completes.
5. When the virtual disk is thin provisioned, check the Thin Provision option.
