Newly added RAID Groups are displayed with a yellow background.

→ When the [Create/Extend Thin Provisioning Pool (Updating Configuration Information)]

screen appears and the operation completes successfully, the [Create/Extend Thin

Provisioning Pool (Result)] screen appears.

When expanding the Thin Provisioning Pool (TPP) capacity, RAID

Groups are added in the TPP. A RAID Group obtains the Resource

according to the volume number, and a single RAID Group is used

as a single volume. After expanding TPP capacity, added RAID

Groups are formatted. When exceeding the maximum capacity of

volumes that can be formatted at the same time, a message to that

effect appears. Wait until the current format process is complete, and

then format the added RAID Groups (unformatted area of the TPP).

• Clicking the [RAID Group No.] link displays the disk drives

configuring the RAID Group.

• When the RAID Group name is changed, the [Create/Extend Thin

Provisioning Pool (Setting RAID Group Name)] screen appears

after the [Create/Extend Thin Provisioning Pool (Updating

Configuration Information)] screen.
