2.
Define a path set by creating a path set definition file from the ISPF panels. The procedures
for these are available in
“Creating a path set” (page 439)
:
•
For an inter-control unit logical path: See
“Defining the inter-CU logical path set” (page 447)
in
“Using the ISPF panels” (page 430)
.
•
For an inter-disk controller logical path: See
“Defining the inter-DKC logical path set”
(page 439)
.
3.
Load and establish a path set:
From the ISPF panels: see
“Establishing a logical path in the reverse direction” (page 115)
in
“Using the ISPF panels” (page 430)
.
Using CLI commands:
1.
Load the path set definition file by executing the
YKLOAD
command with the
PATH
parameter specified.
2.
Establish a logical path by executing the
YKBLDPTH
command.
For more information, see
“The Logical Path Control Function” (page 95)
.
Establishing an Inter-Control Unit logical path
Establish an inter control-unit logical path for the following control units:
•
The control unit containing the copy group
•
The control unit containing the command device
NOTE:
You can define a logical path in one direction even if there is no disk configuration
definition file at the destination site (although there must be one at the source site).
You can establish inter-disk controller logical paths when the storage systems contain Non Gen'ed
volumes or inter-control unit logical paths. However, when establishing, deleting or acquiring the
status of an inter-control unit logical path, if all volumes in the relevant control unit are Non Gen'ed
volumes, you need to set up a route list and register a command device beforehand.
For details about creating an inter-control unit logical path that is dedicated to the command device,
see
“Creating an Inter-Control Unit Logical Path dedicated to the command device” (page 122)
.
Acquiring path information from a storage system
You can acquire the logical path information registered in a storage system in the following
situations:
•
When you want to acquire the logical path information currently defined in the storage system
•
When you want to control, or acquire information for, logical paths other than those for the
defined ports
•
When you need to know the port number to create a path set definition even though a path
has been established
To acquire path information from a storage system, do the following:
1.
Load the path set definition file by executing the
YKLOAD
command with the
PATH
parameter
specified.
2.
Acquire the logical path information defined in the storage system by executing the
YKQRYPTH
command with the
RESTRUCT
parameter specified.
