ProcedureTo Configure Auto-Failback for a Particular Multipathing Support
Symmetrical devices allow for automatic failback to a possible optimal path. If a failover occurs on the initial path, the standby path becomes the new online path. Usually the standby path is a suboptimal path. When auto-failback is enabled, the initial path comes back online, failover to the initial path automatically occurs.
Run the mpathadm list mpath-support command.
# mpathadm list mpath-support
mpath-support: libmpscsi_vhci.so
Select an mpath support name from the output list.
Run the mpathadm modify mpath-support -a [on | off] mpath-support-name command.
# mpathadm modify mpath-support -a off libmpscsi_vhci.so
Run the mpathadm show mpath-support mpath-support-name command to check the change.

Note –
The auto-failback display initiated by the mpathadm modify command setting is effective while the system is running. However, to keep the changed setting persistent, you must update the /kernel/drv/scsi_vhci.conf file. Refer to Configuring Automatic Failback.
ProcedureTo Fail Over a Logical Unit
This operation is applicable only to devices in the following two categories:
Asymmetric devices with a proprietary failover mechanism recognized and supported by multipathing support
Devices conforming to the T10 Standard Target Port Group Support libmpscsi_vhci.so and providing explicit mode asymmetric logical unit access

Select an inquiry-string-name from the output.
Run the mpathadm list Lu -n inquiry-string-name command.

ProcedureTo Configure Auto-Failback for a Particular Multipathing Support
Symmetrical devices allow for automatic failback to a possible optimal path. If a failover occurs on the initial path, the standby path becomes the new online path. Usually the standby path is a suboptimal path. When auto-failback is enabled, the initial path comes back online, failover to the initial path automatically occurs.
Run the mpathadm list mpath-support command.
# mpathadm list mpath-support
mpath-support: libmpscsi_vhci.so
Select an mpath support name from the output list.
Run the mpathadm modify mpath-support -a [on | off] mpath-support-name command.
# mpathadm modify mpath-support -a off libmpscsi_vhci.so
Run the mpathadm show mpath-support mpath-support-name command to check the change.
# mpathadm show mpath-support libmpscsi_vhci.so

Note –
The auto-failback display initiated by the mpathadm modify command setting is effective while the system is running. However, to keep the changed setting persistent, you must update the /kernel/drv/scsi_vhci.conf file. Refer to Configuring Automatic Failback.
ProcedureTo Fail Over a Logical Unit
This operation is applicable only to devices in the following two categories:
Asymmetric devices with a proprietary failover mechanism recognized and supported by multipathing support
Devices conforming to the T10 Standard Target Port Group Support libmpscsi_vhci.so and providing explicit mode asymmetric logical unit access
Run the mpathadm list lu command.

Select a logical unit name from the output.
Run the mpathadm show lu logical-unit-name command.

Run the mpathadm failover lu logical-unit-name command.
# mpathadm failover lu /dev/rdsk/c4t60003BA27D2120004204AC2B000DAB00d0s2
If this operation is successful, the access state of the devices’ target port groups changes as a result of the logical unit failover.
Run the mpathadm show lu logical-unit-name command to verify the access state change.
# mpathadm show lu /dev/rdsk/c4t60003BA27D2120004204AC2B000DAB00d0s2
