How to Identify HBA Cards Ports and WWN in Linux
Too often system administrators require to collect details about host bus adapters in Linux. In this article, we are going to discuss how to identify hba card ports and wwn in linux.
There are many other way and utility which is helpful in getting details but sysfsutils is the package delivered via Red Hat repository which is very helpful while dealing with any kind of HBA details and it usage systool command or script to fetch the required details.
How to Check sysfsutils/systool presence
We can validate the presence of sysutils in your server using the below method.
Method 1 : Use which command
# which systool
/usr/bin/systool
//This is showing path for systool it means sysutils package is already installed.//
Method 2: Use rpm command
# rpm -qa |grep sysfsutils
sysfsutils-2.1.0-16.el7.x86_64
//This is showing package as it is already installed on my server.If it is not it will not display any result.//
How to Install sysfsutils
# yum --enablerepo=* install sysfsutils
