Disabling path in multipath

[satish]

Dear erman,

Thanks for article http://ermanarslan.blogspot.com/2015/01/linux-disabling-path-in-multipath.html?m=1

Here if I am correct,it is for failover case and not for load balancing of io.

I would like to know what he exact command in your case,to enable the path which you have disabled.


echo "- - -" > /sys/class/scsi_host/${HBA}/scan     -> we may scan all the HBA hosts..

Do we have to replace $HBA and —-?

Thank you

Of course you have to replace that.
If you have multiple HBA, you have to run that command for each of them. Or you can write a script for doing the loop for you.
