Storage System node

A Storage System node represents a single storage array chassis. It is the container node for the other nodes modeling the structure of storage entities.

Creation/update

A Storage System node is created or updated when a storage entity is discovered by one of the following:

  • WBEM queries to storage management software triggered by the creation or update of an SI representing storage management software
  • Directly discovered storage using WBEM queries to the WBEM/SMI-S provider triggered by the creation or update of a Storage Device node representing the onboard controller of the storage array chassis
  • Directly discovered storage using SNMP triggered by the creation or update of a Storage Device node representing the onboard controller of the storage array chassis

Removal

The removal of a Storage System node is governed by aging in the same way as Host nodes. However, in the case of the Storage System, it is the relationships between the Storage System and its manager that are aged. The manager is either:

  • The SI representing the management software
  • The Storage Device representing the onboard controller of the storage array chassis

Case 1 - Single manager

When the manager is scanned and the Storage System is no longer discovered, the management relationship begins to age. If it is not discovered in ten days and seven scans (the default), the relationship is removed. If the Storage System has no relationships to a manager, then it is removed.

Case 2 - Multiple managers

Where a Storage System has multiple managers, SIs, Storage Devices, or both, each management relationship ages in the same way as the single manager case. If the Storage System is no longer discovered through a manager, then the relationship between that manager and the Storage System begins to age, and after ten days and seven scans, the relationship is removed. If during this time, the Storage system has been successfully discovered at each scan through a different manager, then the relationship between that manager and the Storage System does not age. Consequently, the Storage System still has a relationship with a manager, and is not removed. When all relationships have been removed, the Storage System is removed too.

When a StorageSystem is removed, all of the nodes it contains are removed. This is Containment Removal, see Containment Removal.
