On Windows Server operating systems, DMP DSM enables configuration of some DSM settings without a storage connection. When a storage array is later connected to a host under an MPIO management, the connected storage array inherits the policy that has been previously set in a DSM.
Support for DSM settings without storage connection applies to operations that are general for storage devices without specific knowledge of a DMP path of a storage device.
The following are settings you can configure for a DSM without storage connection:
Load balances: Active/Active, Active/Passive without choosing a primary path, Least Block, Balanced Path and Least Queue. The specific settings for Round Robin with Subset or Weighted Path load balances cannot be configured without a storage connection because the settings require the specific knowledge of a Volume Replicator path of a disk which does not exist yet.
SCSI-3: Enabling or disabling the setting for SCSI-3 support.
The VEA DSM Configuration command enables viewing a list of installed DSMs on a system and applying load balance settings and SCSI-3 support settings to the selected DSMs. These capabilities are also available through the vxdmpadm utility in the command line interface (CLI). In addition, you can use the CLI vxdmpadm getdsmattrib command to view existing settings for the installed DSMs.
