Page 9: Remote Installation
Installing the host agent on the NAS server Installing the host agent software Storage Area Manager provides two methods for installing the host agent: Install the host agent remotely from the management server to each SAN host Install the host agent locally from the Storage Area Manager CD The NAS servers support both installation methods. - Page 10 Installing the host agent on the NAS server Deleting the properties files After installing the host agent on the NAS server, but before performing a discovery, HP recommends that you delete the NAS properties files on the Storage Area Manager management server.
- Page 11 Discovering the NAS server as a Windows host Discovering the NAS server as a Windows host If no host agent is installed on a NAS server, Storage Area Manager discovers and enters the server under the NAS Devices node. In this context, Storage Area Manager can only monitor the NAS server’s health.
- Page 12 Discovering the NAS server as a Windows host Supported NAS topologies When you install the host agent on the NAS server, Storage Area Manager supports the NAS device as a host, a storage device, and a switch (if present). Storage Area Manager can discover, map, and manage most components of the NAS server in the following topologies: NAS devices with internal storage.
- Page 13 Discovering the NAS server as a Windows host Viewing information about the host When you select the NAS host in the Resources tree or device map, you can view capacity information collected by the host agent. Figure 3 shows the Capacity panel viewed from Storage Builder.
- Page 14 Discovering the NAS server as a Windows host Viewing information about connected devices You can display additional information for the devices connected to the NAS host. For example, Figure 4 shows the Capacity panel for the disks on the NAS host. Figure 4: Disks connected to NAS host This Capacity panel displays the disk space that is visible to the NAS host.
- Page 15 Discovering the NAS server as a Windows host You can use Storage Area Manager’s other features to gain more information from the NAS server acting as a Windows host.
