I 4. Set LUN D1 to a preferred path with the following command:
SET UnitNumber PREFERRED_PATH=THIS_CONTROLLER
Example: set d1 preferred_path=this_controller
T 5. View the initial conditions at the target site. Use the command:
SHOW UNITS
A message appears with information for all units configured to the controller.
T 6. Prepare a LUN on the target subsystem (refer to callout 2 on Figure 13). Use the commands:
INITIALIZE ContainerName
Example: initialize disk10000
ADD UNIT UnitNumber ContainerName DISABLE_ACCESS_PATH=ALL
Example: add unit d10 disk10000 disable_access_path=all
SET UnitNumber ENABLE_ACCESS_PATH=HostIDs
Example: set d10 enable_access_path=BUILDNGAa,BUILDNGAb,BUILDNGAc,BUILDNGAd
SET UnitNumber PREFERRED_PATH=THIS_CONTROLLER
Example: set d10 preferred_path=this_controller
SET UnitNumber MAXIMUM_CACHED_TRANSFER_SIZE=Number
Example: set d10 maximum_cached_transfer_size=128
SHOW UnitNumber
Example: show d10
Example Display 47 shows the characteristics of the created LUN.
