Microsoft Windows Server host attachment

If you have a Windows Server 2012, 2016, or 2019, refer to the requirements and procedures for attaching DS8000® storage to your host with Fibre Channel.

Before you attach a host, refer to the following information:
LUN mapping: When you need access to the data on the target volume, map to the LUNs for the target volumes of the Windows host. This significantly reduces the time that it takes for the host system to restart. If you do not map the LUNs, the system can take up to 10 minutes per Remote Mirror and Copy target volume to map the LUNs. If you map the LUNs, complete the LUN mapping after the Remote Mirror and Copy operation and immediately before you access the data. You must restart the host system before you can access the data on the target volume. Map the LUNs when the target volume is mapped to the host through the DS8000 Storage Management GUI.
