6.6.1.8.1 Prerequisites

You must always perform the setup described below before using a line switching unit resource.

Resource registration

To use a line switching unit, you must first register a switching line resource (SH_SWLine class) to the resource database.

This section describes the procedure for registering a switching line resource to the resource database.

Registration procedure flow

Check the resource name of the line switching unit.
Register the switching line resource.
Check the registration information.

Registration procedure

Confirmation of the resource name of the line switching unit resource
Check the resource names of the line switching units that are registered to the resource database by using the "clgettree(1)" command.
```
# clgettree
Cluster 1 cluster
     Domain 2 CLUSTER
          Shared 7 SHD_CLUSTER
                  SHD_DISK 21 SHD_Disk21 UNKNOWN
                          DISK 22 c5t0d0 ON node1
                          DISK 27 c4t0d0 ON node2
                  SH_SWU 18 SWU2002 UNKNOWN
          Node 3 node1 ON
                  Ethernet 29 hme0 ON
                  DISK 19 c0t0d0 UNKNOWN
                  DISK 22 c5t0d0 ON
          Node 5 node2 ON
                  Ethernet 30 hme0 ON
                  DISK 25 c0t0d0 UNKNOWN
                  DISK 27 c4t0d0 ON
```
In this example, the line indicating "SH_SWU" shows the resource name is "SWU2002". If you cannot confirm the resource name, see "Automatic Configuration" and register the line switching units to the resource database.
- For details on the information that is output by executing the "clgettree(1)" command, see "Explanation of resources related to line switching units."
- For details on the "clgettree(1)" command, see the manual page.
Registration of switching line resources
Execute the "claddswursc(1M)" command to add the switching line resources to the resource database.
```
# claddswursc -k sh_swl_1 -s SWU2002 -0 node1 -1 node2 -m 0x3
```
In this example, the line switching unit called "SWU2002," which was checked in step 2, is used to register the switching line resource called "sh_swl_1."

Port 0 of the switching unit is connected to "node1," and port 1 to "node2."

Since the two switching units LSU01 and LSU00 are to be used, the mask value is set to 0x3.

For details on the "claddswursc(1M)" command, see the manual page.

Confirmation of registration information

Execute the "clgettree(1)" command to check that the switching unit resources of the line switching unit have been registered to the resource database.

Example) Resources of the "SWLine" class are the switching unit resources of the line switching unit.
The resources of the "SH_SWLine" class show a sharing relationship of the switching units for the line switching unit.

[Explanation]

(a) This line identifies a line switching unit resource.: In the example shown in the above figure, "SWU2002" is the resource name of the resource representing the line switching unit.; This resource is displayed when PRIMECLUSTER recognizes the line switching unit when automatic resource registration is executed.
(b) This line identifies a switching line shared resource of the line switching unit.: In the example shown in the above figure, "sh_swl_1" is the resource name of the switching line shared resource (switching line name).; This resource is displayed when the switching line resources of the line switching unit are registered to the resource database with the "claddswursc" command.; As shown in the example of the above figure, this resource belongs to the "SH_SWLine" class.
(c),(d): These lines represent switching line resources of the line switching unit.; In the example shown in the above figure, "sh_swl_1P0" and "sh_swl_1P1" are resource names for switching line resources.; These resources are displayed when the switching line resources of the line switching unit are registered to the resource database with the "claddswursc" command.; As shown in the example of the above figure, these resources belong to the "SWLine" class.
