Summary

displayed

•

Product ID: Indicates the storage system product ID,

emulation type, or model ID (for example,

DF600F

For more details, see

Table 6-11 Product ID displayed

by the view -path operation on page

•

Serial number: The serial number of the storage

system (for example,

0051

You can identify an actual storage system by referencing

the above information from the storage system

management program.

iLU

LU number in the storage system.

This number combined with the storage system name

(shown in

DskName

) identifies the LU that is accessed by a

path.

•

For P9500, indicated by a hexadecimal number. The

first three characters of

iLU

are the CU number, and

the last two characters are the internal LU number

within the CU. The first character of a CU number is 0.

•

For Hitachi AMS2000/AMS/WMS/SMS series, indicated

by a decimal number. The entire value of

iLU

is the

internal LU number within the storage system. You can

identify an actual LU by referencing

iLU

from the

storage system management program.

•

For Universal Storage Platform V/VM and Hitachi Virtual

Storage Platform, indicated by a hexadecimal number.

The first two characters of

iLU

are the number of the

logical DKC (Disk Controller), the middle two numbers

are the CU number, and the last two characters are the

internal LU number within the CU.

ChaPort

Port number of the CHA, which identifies the CHA port that

is mounted on the storage system.

You can identify an actual CHA port by referencing this

number from the storage system management program.

Status

Status of the path

•

Online

: Online

•

Offline(C)

: Offline status caused by a command

operation

•

Offline(E)

: Offline due to an error

Paths that are in

status require corrective

action. The appropriate action can be determined by

referring to

What To Do for a Path Error on page

Type

Attribute of the path

•

Own

: Owner path

•

Non

: Non-owner path
