Risks; Tru64 Unix Configuration - HP StorageWorks 6400/8400 - Enterprise Virtual Array User Manual

Risks

• For nonclustered nodes with a single HBA, a path failure from the HBA to the SAN switch will
result in a loss of connection with storage devices.
• If a host crashes or experiences a power failure, or if the path is interrupted, data will be lost.
Upon re-establishment of the path, a retransmit can be performed to recover whatever data may
have been lost during the outage. The option to retransmit data after interruption is application-
dependent.
