HDLM Operations Using Commands
This section explains how to use the HDLM command. For details on the
various command operations, see Chapter 6, Command Reference on page
6-1.
Notes on Using Commands
• Execute the HDLM command from the VMware vSphere CLI on the remote
management client.
• To specify a parameter value containing one or more spaces, enclose the
entire value in double quotation marks (").
• If you perform either of the following operations, the length of time
required to perform the operation (number-of-paths x one second)
depends on the number of paths that are managed by HDLM:
¢
An online or offline operation to change the status of paths
¢
A set operation to change the load-balance settings
Viewing Path Information
This section explains how to display path information by using an HDLM
command.
To display path information, execute the dlnkmgr command's view operation
with the -path parameter specified. The following example shows how to
execute the command:
dlnkmgr -s host-name -u user-name -p password view -path
To display information only for the paths accessing the specified host device,
execute the dlnkmgr command's view operation with the -path and -hdev
parameters specified. The following example shows how to execute the
command:
PROMPT>dlnkmgr -s host-name -u user-name -p password view -path -
