To display path information

When displaying path information, if you specify either the -item or -c

parameter and also specify the -path parameter, you can select the items to

display and display a summary of path information. This section describes

each parameter, path information and displayed items.

To display path information

-path

When you specify the -path parameter and do not specify either the -c or
-item parameter, the information will be displayed about the HDLM

managed paths without abbreviating or selecting items.
In the sub-parameters (following -path), you can filter the paths to be

listed using -hdev and sort the list using -srt. When you omit both

parameters, the command displays information for all the paths in order

of increasing AutoPATH_IDs.
For details on what is displayed in each item, see

Table 6-12 Path

Information on page 6-42

.

AutoPATH_IDs displayed by the -path parameter depend on the sequence

in which HDLM detects the paths after a host is started up. Because of

this, make sure that you use the path name PathName to identify a path.
The sub-parameters are as follows:

-hdev host-device-name

Displays information only for the paths accessing the specified host

device.
Specify the name of the logical device file (minus the partition

number), /dev/sddlm[aa-pap], for the HDLM device. For details on

logical device files for HDLM devices, see

Logical Device Files for

HDLM Devices on page 2-11

.

The host-device-name string is case-sensitive.

-stname

Use this parameter to display the model ID of the storage system in

the product ID element of the DskName field. When this parameter is

omitted, the command displays the product ID or emulation type of

the storage system instead.
For details about the information displayed for product IDs, see

Table

6-14 Product ID displayed by the view -path operation on page 6-46
