decimal number. The maximum value that can be displayed
is 2

- 1 (4294967295). If the total I/O count reaches the

displayed is 2

count reaches the maximum value, it will re-start from 0..
PathID
The AutoPATH_ID indicated by a decimal number.
The AutoPATH_ID is assigned every time the host is
restarted. When a new LU was added and the host has not
been restarted, AutoPATH_ID is re-assigned to each path of
the LU when you execute the HDLM-configuration definition
utility (dlmcfgmgr).
PathName
#1
- 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 physical path
that will be affected by the change. 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)
For details about each element of the path name and its
representation in Linux, see
Table 6-14 Elements of a path
name on page 6-53.
DskName
#1
DskName
Storage system name, which identifies the storage system
that is accessed by 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).
• Product ID: Indicates the storage system product ID,
emulation type, or model ID (for example, OPEN-3).
For more details, see
Table 6-15 Product ID displayed
by the view -path operation on page 6-53.
• Serial number: The serial number of the storage
system (for example, 15001).
You can identify an actual storage system by referencing
the above information from the storage system
management program.
iLU
