Creating a volume involves a number of tasks and decisions about a variety of elements in your storage configuration. Therefore, before running the New Volume wizard to create a new volume, you should plan your storage.
When you create a volume, be prepared to provide the following information:
Provide a unique name that identifies the volume.
Identify the capacity of the volume in megabytes, gigabytes, or terabytes.
By default, the management software supplies a default storage pool. This pool uses the default storage profile, which implements RAID-5 storage characteristics that can be used in the most common storage environment. Other pools may have also been configured. Before you run the New Volume wizard, check the list of configured pools to see whether one of the pools has the storage characteristics you want. If a suitable pool does not exist, create a new pool using an existing or a new storage profile before you run the New Volume wizard.
A volume can be created on a virtual disk as long as the RAID level, the number of disks, and the disk type (either FC or SATA) of the virtual disk matches the storage profile associated with the volume's pool. The virtual disk must also have enough capacity for the volume. You must determine choose the method of determining which virtual disk will be used to create the volume. The following options are available:
You can add the volume to an existing storage domain, including the default storage domain, or create a new one by mapping the volume to a host or host group. A storage domain is a logical entity used to partition storage that allows a host or host group to have read/write access to the volume. The default storage domain contains all hosts and host groups without explicit mappings and enables them to share access to all volumes that are not explicitly mapped. If you choose to map the volume later, the management software automatically includes it in the default storage domain.
Note -
A host or host group will be available as a mapping option only if an initiator is associated with each individual host and each host included in a host group.
