Configuring an iSCSI vSwitch for multipathing
9 Configuring and Installing the PS Series Multipathing Extension Module for VMware vSphere and PS Series | TR1074
3 Configuring an iSCSI vSwitch for multipathing
The MEM utilizes the same multipathing vSwitch as the VMware native Round Robin multipathing. Therefore,
if the ESXi hosts are already configured for Round Robin, this step can be omitted. However, if the ESXi
hosts are configured for Fixed Path, remove the iSCSI initiator and associated vSwitch before continuing. The
MEM setup.pl script provides powerful functionality and is easy to use compared to the manual configuration
process.
Note: The instructions provided here refer to using the vMA, however, the syntax is the same whether the
vMA or CLI is used. The optional parameters --username and --password have been excluded from the
examples below for clarity. If not included and vi-fastpass is not configured, the user will be prompted to
provide the username and password.
1. Connect to the vMA and change the directory to where the setup.pl was uploaded.
2. Create a multipathing iSCSI vSwitch by invoking the setup.pl in interactive mode.
setup.pl --configure --server=hostname
3.1 Interactive mode configuration
In this configuration mode, a series of questions are posed to the user, and default options presented when
available. To accept a default, press [Enter].
Note: The following example was generated using MEM 1.3 and vSphere 6.0, the output may differ slightly
with other combinations.
setup.pl --configure --server=10.124.6.223
