DYNAMICALLY TRACKING VIRTUAL LOGICAL STORAGE UNITS |
摘要 |
In virtualized environments, storage may be managed dynamically due to the changing data storage requirements. In such environments, logical storage unit identifiers (LUN IDs) may be modified as a result of deleting an existing mapping between physical storage and a virtualization server and recreating the mapping. This can result in I/O request failure. Techniques for resolving errors resulting from LUN ID modifications can be time-intensive and labor-intensive and can disrupt a communication path between a host device and the physical storage. Functionality can be implemented to dynamically identify the LUN ID modifications, determine valid LUN IDs, and retransmit failed I/O requests. This can help minimize I/O request failures due to LUN ID modifications without disrupting the communication path between the host device and the physical storage.
