Snapshot Virtual Disks
5 On the Create Snapshot Virtual Disks – Select Path screen, select the
Simple path.
NOTE:
A snapshot repository virtual disk requires 8 MB of free space. If the
required free space is not available in the disk group of the source virtual disk,
the Create Snapshot Virtual Disks feature defaults to the advanced path.
6 Click Next.
7 Type a name for the snapshot in the Snapshot virtual disk name text box.
8 Type a name for the snapshot repository virtual disk in the Snapshot
repository virtual disk name text box.
9 Click Next.
10 Choose whether to map the virtual disk to a host or host group now or
later:
To map now, select Map now, select a host or host group by clicking it, and
then assign a LUN.
To map later, select Map later.
11 Click Finish to create the snapshot virtual disk and the associated
snapshot repository virtual disk.
12 After you have created one or more snapshot virtual disks, mount or
reassign a drive letter of the source virtual disk.
13 If needed, assign host-to-virtual disk mapping between the snapshot
virtual disk and the host operating system that accesses it.
NOTE:
In some cases, depending on the host type and any virtual disk
manager software in use, the software prevents you from mapping the same
host to both a source virtual disk and its associated snapshot virtual disk.
14 If you are using a Linux-based system, run the
hot_add utility to register
the snapshot virtual disk with the host operating system.
NOTE:
The hot_add utility is not needed for Windows.
