10 Configuring and Deploying the Dell PS Series Multi-Path I/O Device Specific Module with Microsoft Windows | TR1036
3 Installing, configuring and managing the PS Series MPIO
DSM
The PS Series MPIO DSM is included with HIT/Microsoft. For installation guidelines, please refer to the Host
Integration Tools for Microsoft User Guide and Release Notes at eqlsupport.dell.com.
The following section assumes that access control to PS Series volumes has been configured with CHAP
authentication, multiple redundant NIC IP addresses, or a unique iSCSI initiator name. Volume access control
can be added to volumes through the PS Series Group Manager, either at the time of volume creation or
afterwards.
A single ACL record for each host is typically sufficient for enabling volume connections from the MPIO DSM.
When using IP addresses in the ACL, add an ACL record for each interface the host will use to connect to the
volume.
For volumes connecting to cluster configurations, additional steps are needed to assure proper connection.
Select the Enable shared access to the iSCSI target from multiple initiators box in the volume settings
and add an ACL record for each cluster host adapter connecting to the volume. Additionally, there may be
some specific configuration changes needed, including registry changes, to assure that each host in the
cluster is using persistent reservations. Please refer to the latest version of Release Notes for Host Integration
Tools for Microsoft for more information. This documentation is available at https://eqlsupport.dell.com.
