	Configuring and Using Backup Devices
	Shared Devices in the SAN Environment
	In order to share a device among multiple systems, configure one logical
	device for each system on which you want to use the device locally.
NOTE	Before the ATS component can be configured, the MC/ServiceGuard
	configuration has to be completed and a cluster has to exist.

Refer to the following documents for detailed information:

•B3936-90032 Using Advanced Tape Services (MC/ServiceGuard documentation)

•B3935-90015MC/ServiceGuard Version A.11.05 Release Notes

•B3936-90026 Managing MC/ServiceGuard, Sixth Edition

Creating the ATS Configuration Files

Run the stquerycl command to gather the configuration of all attached tape devices and robotic control. This will create the configuration file. The configuration file includes the following new device file names and a usage policy for all devices:

•dev/rmt/st#m

for tape device files

•dev/rac/sac#

for robotic control devices

The configuration files should be the same on all nodes for the same physical device. Both the robotics and drive files should be included.

	Configuring Drives
Floating Drives	Drives that should be accessible from both hosts, depending on which
	host the package is running, have to be configured based on the virtual
	host.
