Improving the transition time in a future release is planned. • Solaris 11 with Brocade Fabric Occasionally, Solaris hosts that are attached through a Brocade fabric lose paths after a failover or failback. In this case the host seems to have a problem with multiple FC_IDs referenced in the RSCN payload from the switch. This is an intermittent issue seen about 10% of the time. Ultimately the fix for this needs to be done on the host and is currently being investigated. • RHEL 6.2 with VXDMP Periodically, there will be multipath errors during failover. These errors describe devices going offline and within seconds the devices are back on line. Improving the transition time in a future release is planned. • AIX 7.1 with VXDMP When an Inserv node is rebooting and failover triggered, the host DMP software marks paths as 'disabled'. The paths are not automatically re-enabled by the DMP restore process. The paths are only restored by issuing the vxdctl enable command or when the InServ node completes rebooting. • HP-UX 11.31 with Symantec Storage Foundation DMP To take advantage of the Persistent ports feature, the following DMP tunables must be disabled: # vxdmpadm settune dmp_fast_recovery=off # vxdmpadm settune dmp_monitor_fabric=off 18 HP 3PAR OS 3.1.2 GA Release Notes

Solaris 11 with Brocade Fabric
Occasionally, Solaris hosts that are attached through a Brocade fabric lose paths after a
failover or failback. In this case the host seems to have a problem with multiple FC_IDs
referenced in the RSCN payload from the switch. This is an intermittent issue seen about 10%
of the time.
Ultimately the fix for this needs to be done on the host and is currently being investigated.
•
RHEL 6.2 with VXDMP
Periodically, there will be multipath errors during failover. These errors describe devices going
offline and within seconds the devices are back on line.
Improving the transition time in a future release is planned.
•
AIX 7.1 with VXDMP
When an Inserv node is rebooting and failover triggered, the host DMP software marks paths
as ‘disabled’. The paths are not automatically re-enabled by the DMP restore process. The
paths are only restored by issuing the
vxdctl enable
command or when the InServ node
completes rebooting.
•
HP-UX 11.31 with Symantec Storage Foundation DMP
To take advantage of the Persistent ports feature, the following DMP tunables must be disabled:
# vxdmpadm settune dmp_fast_recovery=off
# vxdmpadm settune dmp_monitor_fabric=off
