HP B6960-90078 manual Library Robotics, A Cluster, Manually Configuring the Devices Drives

	Configuring and Using Backup Devices
	Shared Devices in the SAN Environment
Prerequisite	Before configuring Data Protector devices in a SAN environment, the
	Data Protector Media Agent must be installed on each host that needs to
	communicate with the shared library. See the HP OpenView Storage
	Data Protector Installation and Licensing Guide for more information on
	installing a Media Agent.
Configuring the	To create the library itself, refer to “Configuring Library Devices” on
Library Robotics	page 29 or to the online Help topic “Configuring Devices in a SAN
	Environment”.
	For robotics control, you can use any host within the SAN; here the
	system dupin.company.com is used. The library robotics will be
	controlled by that host, unless the host is unavailable and direct access is
	enabled as explained in detail in “Enabling Direct Access” on page 55.
Configuring the	If you want the robotic control to be managed by a cluster, you need to
Library Robotics	make sure that:
in a Cluster	• The robotics control exists on each cluster node.
	• The virtual cluster name is used in the library robotics configuration.
	• The common robotics and device filenames are installed either using
	the mksf command or using the libtab file. For information on how
	to configure the libtab file, refer to “Manually Configuring the libtab
	Files” on page 56.
	After you have configured the library robotics, create the drives.
	Manually Configuring the Devices (Drives)
	You need to configure each device (tape drive) on each host from which
	you want to use the device.
	Lock Names must be used to prevent the same device from being used by
	several hosts at the same time. Optionally, the “direct access” mode can
	be selected.

Configuring Drives As will be seen shortly, it helps to follow a drive naming convention similar to the following:

LibraryLogicalName_DriveIndex_Hostname, for example

SAN_LIB_2_computer_1.
