dlmodmset Utility for Setting the HDLM Execution
Environment ODM
This utility sets and displays ODM to define HDLM operations.
Format
/usr/DynamicLinkManager/bin/dlmodmset
{{-r {on | off}
| -i {on | off}
| -v {on | off}
| -j {on | off}} [-s]
| -o
| -h }
Parameters
-r { on | off }
Enables or disables the LUN RESET option.
on: Enable
off: Disable
The default is off.
To use GPFS, specify on.
You do not need to reconfigure the hdisk or restart the host when you
change this parameter.
-i { on | off }
Prevents I/O on the Online(E) path.
on: Prevents I/O on the Online(E) path.
off: Allows I/O on the Online(E) path.
The default is off.
When an error (such as one that might occur in a LVM mirror
configuration) is detected and I/O access for a path in the Online(E)
status continues, detection of errors will continue. When this parameter is
set to on, I/O access is suppressed until troubleshooting measures are
taken. This can shorten the time needed to deal with the problem.
You do not need to reconfigure the hdisk or restart the host when you
change this parameter.
Note
When this parameter is set to on, I/O access to the Online(E) path will
be suppressed, so I/O success will automatically change the path to
the Online status. To recover the path, use an online command or
the auto failback function.
-v { on | off }
Enables or disables the NPIV option.
