Advanced SVSP virtualization functionality
This section will demonstrate the advanced functions of SVSP:
• Creating PiTs and snapshots and assigning host permission to snapshots.
• Deleting PiTs.
• Rolling back a snapshot.
• Creating snapclones.
• Performing migrations.
• Establishing asynchronous and synchronous mirrors
Creating a PiT
A snapshot is an application that allows you to create low-capacity copies of your virtual disks. The
snapshot makes data available to the host for testing or backup purposes, and updates production
data without interruption.
SVSP snapshot functionality has two functional parts:
• Point-in-Time (or PiT)
• Snapshot
First, you have to create a PiT, which is a snapshot that is not presentable to any host. It is like a
bookmark on a time axis. Only after you have created a PiT, can you present a snapshot. In fact, you
can create multiple snapshots on the same PiT. To create a PiT on a specific virtual disk:
