Getting started with shared storage pools by using the VIOS configuration menu
Learn about using the Virtual I/O Server (VIOS) configuration menu to manage shared storage pools.
On VIOS Version 2.2.0.11, Fix Pack 24, Service Pack 1, or later, you can create a clustering configuration. VIOS partitions connected to the same shared storage pool must be part of the same cluster. Each cluster has a default storage pool. You can use the VIOS command-line interface to manage shared storage pools.
- On VIOS Version 2.2.0.11, Fix Pack 24, Service Pack 1, a cluster consists of only one VIOS partition.
- VIOS Version 2.2.1.0 supports only one cluster in a VIOS partition.
- On VIOS Version 2.2.1.3, or later, a cluster consists of up to four networked VIOS partitions.
- On VIOS Version 2.2.2.0, or later, a cluster consists of up to 16 networked VIOS partitions.
To access VIOS configuration menu, run the cfgassist command from the command-line interface. On the VIOS configuration menu, move the cursor to the Shared Storage Pools menu and press Enter. Use the submenus to manage clusters, VIOS logical partitions, storage pools, and logical units in shared storage pools.
To select information, such as existing cluster names, associated storage pool names, snapshot names, and logical unit names on the Shared Storage Pools menu, you can use the following wizards on the VIOS configuration menu:
- Cluster and Storage Pool Selection wizard: On the Shared Storage Pools menu, you can use the Cluster and Storage Pool Selection wizard to select the name of an existing cluster and associated storage pool. The Cluster and Storage Pool Selection wizard displays the set of cluster names. After you select a cluster, the wizard displays the names of the associated storage pools.
- Logical Unit Selection wizard: On the Manage Logical Units in Storage Pool submenu, you can use the Logical Unit Selection wizard to select the names of logical units. You can identify multiple logical unit names, redisplay the Logical Unit Selection wizard, and change the logical unit selection.
- Snapshot Selection wizard: On the Manage Logical Units in Storage Pool submenu, you can use the Snapshot Selection wizard to select snapshots and logical units. You can select cluster names and the storage pool name.
