HP Hitachi Dynamic Link Manager Software Licenses - Manual (Page 418)

This storage system applies when the dynamic I/O path control function is
disabled.
To display HBA port information
-hba
Use this parameter to display information about the paths that pass
through each HBA port. HDLM displays the unique HBA port ID assigned
to each HBA port. This HBA port ID is used in monitor operations, and
can also be used in Offline and Online operations. The following table
lists and describes the displayed items.
Table 6-19 Items Displayed as HBA Port Information
Item Description
HbaID HBA port ID
Port.Bus Port (host port number in hexadecimal) and Bus (bus number in
hexadecimal), separated by a period
HBAPortWWN A 16-digit hexadecimal number indicating the WWN information
for an HBA connected to the storage system.
This item is displayed only when you specify the following:
IO-Count Total I/O count for the displayed paths, indicated by a decimal
number. The maximum value that can be displayed is 2
32 - 1
(4294967295). If the total I/O count reaches the maximum value,
it is reset, and the count is re-started from 0.
IO-Errors Total I/O error count for the displayed paths, indicated by a
decimal number. The maximum value that can be displayed is 2
32
- 1 (4294967295). If the total I/O error count reaches the
maximum value, it is reset, and the count is re-started from 0.
Paths Total number of displayed paths, indicated by a decimal number.
OnlinePaths Number of available paths in the displayed paths, indicated by a
decimal number. When the value of Paths equals the value of
OnlinePaths, all paths are online. If the value of OnlinePaths is
less than that of Paths, some paths might have an error status, in
which case you should check the status of individual paths and
take appropriate action for any paths that have an error status.
Physical
Device HBA port configuration information. The names of the physical
device files under the /devices directory are displayed.
