Find Your HBA Connection

This post will show the information on how to find your HBA WWN and where you HBA is connected.

# lsdev -Cc adapter

# lsdev -p fcs0

fcs0 is made up of fscsi0 and fcnet0.

fscsi is the channel used for the transfer of data over FC HBA.

# lsattr -EHl fscsi0

And locate the field called "connected_to" which will show where you HBA is connected.

Boot Information in NVRAM

NVRAM : Non-volatile Read Only Memory.

Its a memory on which the information about disk is stored.

# bootlist -m both -o -v

The output of this file will be similar to /etc/path_to_inst file in Solaris.
