Chapter 6. Basic volume and host configuration

The All Volumes window opens (Figure 6-2). If this the first time volumes are configured on a
newly initialized system, a pop-up message indicates that no volumes are yet defined.
Figure 6-2 All Volumes window
We have some volumes already and are creating additional volumes in the following sections.
By default, all volumes that you create are striped across all available MDisks in one storage
pool. The GUI for IBM Flex System V7000 Storage Node provides the following preset
selections for the user:
򐂰 Generic: A striped volume that is fully provisioned, as described in 6.1.1, “Creating a
generic volume” on page 258.
򐂰 Thin-provisioned: A striped volume that is space efficient. There are choices under the
Advanced button to help determine how much space is fully allocated initially and how
large the volume is able to grow, as described in 6.1.2, “Creating a thin-provisioned
volume” on page 260.
򐂰 Mirror: The striped volume consists of two striped copies and is synchronized to protect
against loss of data if the underlying storage pool of one copy is lost, as described in 6.1.3,
“Creating a mirrored volume” on page 262.
򐂰 Thin-mirror: Two synchronized copies. Both are thin provisioned, as described in 6.1.4,
“Creating a thin-mirror volume” on page 266.
򐂰 Compressed: A volume using embedded Real-time Compression technology for reducing
the size of the volume, before it is stored on the disk. For additional help, see “Creating a
compressed volume” on page 270.
Select the volume type you want to create and go to the relevant section.
