Abstract
A method, a system and a computer program for determining device criticality during SAN reconfiguration operations comprising the steps of building the SAN connectivity graph and mapping the reconfiguration on SAN connectivity graph; locating the affected host systems; and determining the device criticality for each of the affected host systems. The hosts systems may also be provided with impact analysis agents to generate device criticality on host systems and a central agent to aggregate the device criticality from impact analysis agent and provide feedback to data center administrator.
Claims20
A method for determining device criticality for reconfiguration of a storage area network comprising the steps of:
- building a storage area network connectivity graph;
- identifying the host systems affected by a reconfiguration operation from storage area network connectivity graph;
- and
- evoking a critical resource analysis algorithm for each affected host system to determine the affected resources on the affected host systems.
Apparatus for determining device criticality for a reconfiguration operation of a storage area network comprising:
- a central agent for locating the host systems affected by a reconfiguration operation from a storage area network connectivity graph;
- and
- an impact analysis agent for evoking a critical resource analysis algorithm for each affected host system to determine the affected resources on the affected host systems.
A computer program product for execution by a server computer for determining device criticality for reconfiguration of a storage area network comprising the steps of:
- building a storage area network connectivity graph;
- identifying the host systems affected by a reconfiguration operation from storage area network connectivity graph;
- and
- evoking a critical resource analysis algorithm for each affected host system to determine the affected resources on the affected host systems.
