• Using the MEM with AutoDeploy Obtaining the MEM Installation File The Dell EqualLogic MEM installation .zip file is available from the Technical Support website. The .zip file has the following contents: • setup.pl - A configuration and installation script. To use this script, install the vSphere - Dell EqualLogic PS6210E | EqualLogic Multipathing Extension Module Installation - Page 10
the Dell EqualLogic installation script setup.pl for network configuration operations. Prerequisites for setup.pl Script The setup.pl script is designed to run from the VMware Management Assistant (vMA) or the vSphere CLI from a Linux or Windows host. vSphere CLI version 6.x is supported. NOTE - Dell EqualLogic PS6210E | EqualLogic Multipathing Extension Module Installation - Page 11
the Dell EqualLogic MEM To configure your vSwitch for the Dell EqualLogic MEM , use the following syntax: setup.pl --configure --bestpractices nohwiscsi Ignores any supported iSCSI offload network cards, and uses only the VMware software iSCSI initiator.
