ShadowImage for Mainframe feature enabled on the Remote Web Console computer. The SIz
system requirements are as follows.
Volume Requirements
The requirements for the volumes to be used as SIz pairs are as follows:
• RAID level
The RAID level combinations of the S-VOL and the T-VOL of an SIz pair must be one of the
following.

• Types of volumes
Besides normal volumes, you can use external volumes and custom-sized volumes. When using
external volumes or custom-sized volumes note the following points:
◦ External volumes
The license for XP External Storage is required.
◦ Custom-sized volumes
The license of Virtual LVI is required. To create an SIz pair with custom-sized volumes,
S-VOL must be paired with T-VOLs of the same capacity and the same emulation type.
