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:

for multiple paths follow the high availability cabling guidelines published in the
