Compatibility Between Storage Allocater and Storage Provisioner

HP OpenView Storage Allocater is an allocation product in the Storage Area Manager suite. Storage Allocater's main focus is to provide host-based, logical unit security management for the SAN. It provides the ability to allocate and deallocate storage to or from a host.

HP OpenView Storage Provisioner is a provisioning application that can optionally be installed on the SMA. This software manages both HSG- and HSV-based storage subsystems. Storage Provisioner allows storage providers to manage storage as a utility, customize service levels, and grant consumers self-service access to storage via quotas. Storage Provisioner also creates usage reports to support billing for both storage providers and consumers.

It is possible to have both of these products installed on the SMA with no technical problems. However, if you use both products simultaneously, conflicts and data corruption can occur if they attempt to allocate the same storage.

For example, you can assign a LUN to a host using Storage Allocater. However, if you then use Storage Provisioner, the LUN appears to be available and Storage Provisioner could reassign the same LUN, causing information to be overwritten.

Caution: HP recommends, as a best practice, that you use either Storage Allocater or Storage Provisioner, but not both, for storage provisioning. If you choose to use both, ensure that the two applications do not attempt to manage the same host and storage resource. Otherwise, data corruption can occur.
