Path Name: The path name, which indicates a path. When you modify the system
configuration or replace a hardware item, you should check the path names to identify the
paths that will be affected by the change. A path name consists of the following four
elements, separated by periods:
„
Host port number (hexadecimal number)
„
Bus number (hexadecimal number)
„
Target ID (hexadecimal number)
„
Host LU number (hexadecimal number)
Table 6.7 shows the elements of a path name and their representation in Windows.
Table 6.7 Elements of a Path Name
Element Windows Representation
Host port number (hexadecimal) (example: 0004, 0005) SCSI port number
Bus number (example: 0001) SCSI bus number
Target ID (example: 0000000000000000,
000000000000007A)
Target Id
Host LU number0001) Logical Unit ID or LUN
The path name corresponds to the following information:
„
Information shown in the Computer Management window.
„
The information in the following registry: HKEY_LOCAL_MACHINE\HARDWARE\
DEVICEMAP\Scsi
Note: When an FC connection is used, the target ID of a SCSI is determined based on the HBA
configuration. For details on the target ID, see the relevant documentation, such as the HBA
manual.
System: This column displays the names of the corresponding storage system to which each
path is connected. This name allows you to specify the storage system to be accessed via a
path. A storage system name consists of the following three elements, separated by periods:
„
Vendor ID: The name of the storage system vendor (for example, HITACHI).
„
Model ID: Indicates the model name of the storage system (for example, 9970/9980
indicates the Lightning 9900V Series).
„
Serial number: The serial number of the storage system (for example, 03A97).
You can physically specify a storage system by referencing these elements of information
from the storage system management program.
Table 6.8 shows the model IDs displayed in the Path List view, and the model names of
corresponding storage systems supported by HDLM.
