There are multiple tasks to add DMP DSMs on each server. The order in which the tasks are done in relation to the rest of the configuration depends on whether you are installing a new configuration or upgrading an existing cluster configuration. Detailed steps are presented in later sections.
In summary, the tasks are the following:
Install a second host bus adapter in each server. Do not connect the second path to each additional switch at this point. The path must be left unconnected.
For a new install, this step can be done with the initial hardware configuration before the servers are running.
For an existing cluster system, a rolling upgrade procedure is used to allow installation of the hardware and software on the inactive node on the cluster. When the installation of one node is complete, switch the active node and complete the hardware and software installation on the remaining node that is inactive.
Install InfoScale Enterprise on the inactive node.
Product installation requires a reboot, and this avoids rebooting the active node of the cluster.
Using appropriate cables, connect the second path on Server A to the second switch. Configure the switch, if necessary. Do the same for the second switch on Server B.
Verify that both paths are under DMP DSMs control.
Access the Array Settings dialog for each array and make sure that the array load balancing settings are set to active/passive.
