Multipath management via Veritas Storage
Foundation Dynamic Multipathing (DMP)
In dynamic multipath storage environments, the XIV Storage System
bridges the storage-host information gap by passing important storage-
related device information to Storage Foundation. Extended storage
attributes, such as the ability to support reclamation, minimum chunk size
and maximum reclaimable space size, are exposed to the host in order to:
● Allow informed decision-making by system administrators.
● Reduce errors by promoting data accuracy and completeness.
● Facilitate space reclamation.
● Enhance troubleshooting abilities.
