IBM Server Storage Provisioning Tool Installation and Users Guide

Short Description
Use the IBM Server Storage Provisioning Tool to allocate or deallocate volumes on a supported remote storage network and to save and restore network-storage configurations. IBM Server Storage Provisioning Tool adds a set of dircli commands that you can use to allocate or deallocate volumes on a supported remote storage network. It also adds options to the BladeCenter Configuration Manager task that you can use to save a SAN configuration profile that can be applied to new blade servers when they are added or replaced, effectively remapping the remote storage to the new blade.

Storage subsystems
A storage subsystem is a device that coordinates and controls the operation of one or more disk drives. A storage subsystem also synchronizes the operation of the drives with the operation of the system as a whole, including the RAID management.
Storage subsystems that are attached to the SAN fabric provide the physical storage devices that the cluster detects as managed disks (MDisks). The nodes in the cluster are connected to one or more Fibre Channel SAN fabrics.
Note: Clustering in a Serial Attached SCSI (SAS) storage environment is not currently supported by IBM Director or IBM Server Storage Provisioning Tool.
Storage subsystems reside on the SAN fabric and are addressable by one or more Fibre Channel or SAS ports. Each port has a unique name known as a worldwide port name (WWPN).
The exported storage devices are detected by the cluster and reported by the user interfaces. The cluster can also determine which MDisks each storage subsystem is presenting, and can provide a view of MDisks that is filtered by the storage subsystem. This enables you to associate the MDisks with the RAID that the subsystem exports.
