Installing the Host Utilities from the command line
You can perform a quiet (unattended) installation of the Host Utilities by entering the
commands at a Windows command prompt. Enter the following command at a Windows
command prompt:
msiexec /i installer.msi /quiet
MULTIPATHING={0 | 1}
[INSTALLDIR=inst_path]
where:
򐂰 installer is the name of the .ms i file for your processor architecture.
򐂰 MULTIPATHING specifies whether MPIO support is installed. Allowed values are 0 for no or
and 1 for yes.
򐂰 inst_path is the path where the Host Utilities files are installed. The default path is
C:\Program Files\IBM\Windows Host Utilities\ .
17.4.4 Host configuration settings
You must collect some host configuration settings as part of the installation process. The Host
Utilities installer modifies other host settings that are based on your installation choices.
Fibre Channel and iSCSI identifiers
The storage system identifies hosts that are allowed to access LUNs. The hosts are identified
based on the Fibre Channel worldwide port names (WWPNs) or iSCSI initiator node name on
the host.
Each Fibre Channel port has its own WWPN. A host has a single iSCSI node name for all
iSCSI ports. You need these identifiers when you are manually creating initiator groups
(igroups) on the storage system.
The storage system also has WWPNs and an iSCSI node name, but you do not need them to
configure the host.
Recording the WWPN
Record the worldwide port names of all Fibre Channel ports that connect to the storage
system. Each HBA port has its own WWPN. For a dual-port HBA, you must record two
values; for a quad-port HBA, record four values.
Tip: The Windows Host Utilities installer checks for required Windows hotfixes. If it
detects a missing hotfix, it displays an error. Download and install the requested
hotfixes, then restart the installer.
