Do not use a DMP DSM together with a third-party DSM for the same array. Only one DSM at a time can claim the LUNs in an array. According to Microsoft Multipath I/O (MPIO) documentation, if multiple DSMs are installed, the Microsoft MPIO framework contacts each DSM to determine which is appropriate to handle a device. There is no particular order in which the MPIO framework contacts the DSMs. The first DSM to claim ownership of the device is associated with that device. Other DSMs cannot claim an already claimed device. Therefore, to ensure that the DMP DSM claims the LUNs of an array, no other DSM should be installed for that same array.
If you are upgrading the product using the product installer, do not clear the selection for the DSMs you want to remove. Clearing the default selection does not remove the installed DSMs.
To remove the DSMs, perform any one of the following:
Before you begin to upgrade the cluster, remove the required DSM, using the Windows Add or Remove Programs. Reboot the node and then perform the upgrade.
Upgrade the cluster and then use the Windows Add or Remove Programs to remove the DSM.
Upgrade the cluster and then navigate to %ALLUSERSPROFILE%\Veritas\MPIO\.
From the command prompt, run the following command:
instdsm.exe - u DSMName.inf
If you are upgrading the product using CLI, you must specify the previously installed options in the OPTIONS parameter, else they will be uninstalled. To include the previously installed options in this parameter, either specify these options individually in the OPTIONS parameter or specify "Installed" in the OPTIONS parameter to upgrade all options (example: options="Installed,flashsnap" ).
If you install InfoScale Availability on a system where you have already installed Veritas InfoScale Storage and have configured Microsoft Failover Cluster, you must first unconfigure the Microsoft Failover Cluster and remove the SFW component for Microsoft Failover Cluster.
To unconfigure Microsoft Failover Cluster, refer to Microsoft documentation.
To remove the SFW component for Microsoft Failover Cluster, use Windows Add Remove Programs.
If you install InfoScale Storage on a system where you have installed InfoScale Availability, you cannot specify the Microsoft Failover Cluster option.
