OpenVMS Path Failback In very specific configurations utilizing multiple OpenVMS hosts connected to multiple ports of an HP StorageWorks SAN Switch 2/32, it is possible that not all paths will re-establish to a switch after a failover/failback failure scenario. In all cases where a path failure occurs, initial path failover to an alternate path occurs as expected, with no loss of data. Once the initial failed path is repaired however, it is possible under certain rare conditions, for the failback sequence to the repaired path to be unsuccessful. HP believes the likelihood of occurrence is extremely low and has only encountered this condition under extensive, multiple repeated failover/failback test sequences. This condition is expected to be corrected in a future release. Note: HP strongly recommends that customers periodically monitor device status to verify access is available on all configured paths. HP further recommends that cabling for multiple paths follow the high availability cabling guidelines published in the HP StorageWorks SAN Design Reference Guide, which specifies to connect each path in a multi-path configuration to a different Fibre Channel switch. Monitoring Status of Device Paths Periodically use the show dev/full or show dev/multi command to display status of device paths. If a path is determined to be missing, follow the procedure below to restore the path. Restoring Missing Device Paths Restore device paths in one of two ways: ■ By disabling/enabling the affected switch port, or ■ By disconnecting/reconnecting the affected HBA cable at the HBA or at the switch port.
