Linux MPIO works if host setup is completed. The host setup is broadly classified as HBA setup, HBA driver parameter setup, Multipath setup, LVM setup, and SnapDrive for UNIX setup.
More information
HBA setup
HBA Setup is the process of installing an appropriate HBA Card and the supported drivers on a Linux host.
Setting up HBA driver parameter
To set up HBA driver for Linux MPIO, the exact sequence of steps required depends on the operating system used. The setup also depends on the HBA card used.
Multipath configuration variables
You need to change few configuration variables in the snapdrive.conf file for MPIO to work with Linux.
