Installing the MEM
12 Configuring and Installing the PS Series Multipathing Extension Module for VMware vSphere and PS Series | TR1074
4 Installing the MEM
The MEM can be installed using the command-line tools (CLI or vMA) or with vSphere Update Manager
(VUM). The command-line tools are used in the example in this section. See appendix B for installation
instructions using VUM.
Setup.pl is a Perl script wrapper around a number of VMware CLI commands. It provides administrators with
a similar installation process, regardless of the vSphere version.
Note: Prior to installation, setup.pl copies the VIB to the first datastore it finds if a particular datastore has not
been specified using the --datastore parameter. Due to API limitations, the VIB is not deleted by setup.pl.
Note: When performing an upgrade or uninstall of the MEM, a reboot is required on all versions of vSphere.
1. Using the vMA or vSphere CLI, install the MEM on each host with the command:
setup.pl --install --server=hostname
It may take a few minutes to install the module to the ESXi host.
2. Reboot the ESXi host to enable the plugin multipathing functionality. This may be done manually
during the host configuration process or automatically after the MEM module is installed by
appending the –-reboot parameter to the above command line.
3. To verify the availability of the MEM, execute the command:
setup.pl --query --server=hostname
As shown in the following, running this command displays the presence and status of the MEM on the
host and any volumes it is the active PSP for.
