HP XP7 Storage - Manual (Page 67)

Note:
The folder that stores the Hitachi Command Suite Common Agent
Component commands is automatically added to the PATH environment
variable of the remote management client. So, when executing the
command, there is no need to move the current folder to the folder
storing the command.
Checking the Path Configuration
HDLM functions, such as load balancing and failover, are only available for
HDLM management-target devices that have more than one active path. After
you install HDLM or change the hardware configuration, check the structure
and statuses of the paths.
You can use the HDLM command's view operation from the remote
management client to check path information.
The following describes how to check path information by using the dlnkmgr
command's view operation. For details about the view operation, see view
(Displays Information) on page 6-25 .

.
Execute the following command:
dlnkmgr -s host-name -u user-name -p password view -path >
redirect-destination-file
2
.
Open redirect-destination-file and check the following:
¢
Make sure that there is at least one LU being accessed by a path.
A path can be identified by PathName. The LU that is accessed by a
path can be identified by both DskName and iLU.
¢
Make sure that all the paths are online.
Make sure that PathStatus is Online. If a path is not online, Reduced
will be displayed.
¢
Make sure that for each path the combination of the CHA port
(ChaPort), through which multiple paths are accessing the same LU,
and the HBA port (the host port number and bus number displayed in
the PathName column) is different.
The digits displayed on the left of PathName indicate a host port
number. The numbers displayed between the period to the right of the
host port number and the next period indicate a bus number.
Setting Up HDLM
HDLM includes functions like the load balancing function, the audit logging
function, etc. You can configure these functions by using the HDLM
command's set operation from the remote management client. This section
describes how to set up the HDLM functions.
