How many SAN switches connected to my AIX server

Hope you all are aware of it nowadays we are mostly using SAN disks. It is highly important to know out disks and the adapter details. Fiber channel is used for lightning fast communication and to access the data. Data Read/Write to the San Disks have some protocols. Will see it later. Here is the commands to check the disks and Adapter details

# lsdev |grep fc
# lsattr -El fscsi0 |grep -i scsi_id

Example 1

# 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
