Corrective Measures

■Check that the /kernel/drv/scsi_vhci.conf configuration is correct.

■Make sure mpxio-disable=nois set.

■Check /var/adm/messages for errors.

■For Sun StorEdge T3 Array installations, make sure the sys mp_support setting is set to mpxio.

If the problem persists, contact your Sun Service representative.

Problem

Failing a path (to secondary or to primary) does not succeed using Sun StorEdge Traffic Manager.

Corrective Measures

■Check the luxadm display output on the disk/LUN to verify that the secondary path is STANDBY.

If the path is not STANDBY, it cannot be used as a failover path.
