Integration of EMC SAN with linux

Integrating Linux with EMC SAN

For integrating linux with EMC, you need to install two software available on emc’s website.

1.Powerpath (To remove multipaths)
2.NaviHost Agent (To register linux machine on EMC storage)

Following are the commands to integrate linux

1.  To check OS Details
# uname –a

2. To check OS release
# cat /etc/redhat-release

3. To check FC HBA Card 
# lspci | grep -i fibre

4. To check WWPN in linux
# cat /sys/class/fc_host/host4/port_name

5. To check installed package
# rpm –qa |grep –I p <package name>

6.  Install both packages by using following command
# rpm –ivh <package name> ( navihost and powerpath)

8. Check status and start the navishost agent
# service naviagent status
# service naviagent start

9. Start & check emcpowerpath service 
# /etc/init.d/PowerPath start (As service command may not work for powerpath)
# ps –ef |grep –I powerpath

10. Check powerpath disk and paths
# powermt display dev=all

11. Check the newly added disk from SAN
# fdisk –l, or #parted -l 

12.  make partition on the disk received from SAN
# fdisk <disk name>

13. format it and mount it.
# mkfs.ext4 <partition name>

Create one directory
#mkdir /emc

Mount the partition on directory
#mount /dev/emcpowera(partition name)  /emc

If needed add the entry in /etc/fstab to make it permanent mount

    Hi Musab,
    I find the below command also very useful while determining the HBA info on a SUSE Linux host.
    #systool -av -c fc_host

    Could you please let me know if this works on other Linux distros as well?

    Hi sagar,
    I would first like to welcome you on our blog.

    Regarding your question,
    Yes the same command can also be run on other distributions as well especially RHEL AND CENTOS, but to make use of it you need to install the following package.


    by default it is not available, but comes in DVD as additional package.

    Hope that answer your question

    Thank you very much.
