Sometimes AIX Admin need to be sure that the System is connected to different SAN Switch for more redundancy and stability.
Follow below steps to check SAN Switches from AIX Side:
# lsdev |grep fc fcs0 Available 24-T1 Virtual Fibre Channel Client Adapter fcs1 Available 24-T1 Virtual Fibre Channel Client Adapter # lsattr -El fscsi0 |grep -i scsi_id scsi_id 0xdf0707 Adapter SCSI ID False # lsattr -El fscsi1 |grep -i scsi_id scsi_id 0xde0718 Adapter SCSI ID False
0xdf & 0xde means that the 2 FC adapter are connected to 2 different SAN Switch
Above Steps Tested on AIX 6.1 & 7.1
