Network fabric events may be utilized to proactively handle network path
outages. A storage network virtualization manager may receive a network
fabric event indicating a failure along a network path to a storage
device and in response may initiate a proactive error handling mechanism.
A storage network virtualization manager may proactively handle a network
path failure before I/O requests via that network path fail. The
proactive error handling mechanism may be initiated and completed prior
to or without a host receiving an indication that an access request to a
storage device on the network path has failed. Proactive error handling
in response to network fabric events may reduce the number of I/O
failures and retries and may also reduce the length of time access
requests to storage devices affected by a network fabric path failure
must be quiesced.
