Configuring an iSCSI vSwitch for multipathing
11 Configuring and Installing the PS Series Multipathing Extension Module for VMware vSphere and PS Series | TR1074
3.2 Unattended mode configuration
While setup.pl scripts interactive mode is extremely helpful, using it to configure all the hosts in a cluster is not
efficient. Instead, passing the values of the various parameters to the setup.pl script provides a more efficient
means of configuring several hosts.
At the end of the interactive mode configuration, the resulting command-line questions and answers are
presented as shown in the example below.
setup.pl --configure --server=10.124.6.223 --vswitch=vSwitchISCSI
--mtu=9000 --nics=vmnic2,vmnic3 --ips=192.168.0.215,192.168.0.216
--netmask=255.255.255.0 --vmkernel=iSCSI
--nohwiscsi --enableswiscsi --groupip=192.168.0.200
--chapuser=BLUEcluster
Using this as an example, modify the hostname and IP information to provision additional ESXi hosts with the
same vSwitch configuration.
setup.pl --configure --server=10.124.6.224 --vswitch=vSwitchISCSI
--mtu=9000 --nics=vmnic2,vmnic3 --ips=192.168.0.225,192.168.0.226
--netmask=255.255.255.0 --vmkernel=iSCSI
--nohwiscsi --enableswiscsi --groupip=192.168.0.200
--chapuser=BLUEcluster --chapsecret=BLUEsecret
Note: The CHAP secret is not displayed as part of the generated interactive mode command line, but was
added to the example above. If it is not included, setup.pl will prompt for the CHAP secret at run time, if a
CHAP user is specified.
Depending on the required configuration of the multipathing iSCSI vSwitch, additional parameters may be
required or removed. For a full list of parameters and their defaults, see “Configuring Your Network for the
MEM Plugin” in the EqualLogic Multipathing Extension Module Installation and User Guide.
