Setting up HPDM Multipath Setting up HPDM Multipath includes configuring HBA parameters for multipathed environment. This involves the following: • Configuring QLogic HBA parameters • Configuring Emulex HBA parameters Configuring QLogic HBA parameters To configure the QLogic HBA parameters for QLogic 2xxx family of HBAs, complete the following steps: 1. Edit the /etc/modprobe.conf file in RHEL hosts and /etc/modprobe.conf.
NOTE: Ensure you have a HBA driver installed in single path mode. For more information, see the installation and reference guides for the respective HBA drivers. Setting up Device Mapper Multipath daemon You must set the Device Mapper Multipath daemon to start at boot time. For RHEL hosts, complete the following steps to start the multipathd daemon at boot time: 1. Run the following command to check if the daemon is configured to start at boot time: # chkconfig --list multipathd 2.
