7. Utility Reference

-s
Specify this parameter when you do not want to display the confirmation
messages during execution of the
dlmcfgmgr
utility. When you execute this
utility with this parameter specified, the confirmation message for each HDLM
device is not displayed.
Use this parameter when you want to skip a response to the confirmation message
(to eliminate the manual intervention). For example, use this parameter when
executing a command using a shell script or batch file.
When you specify the
-v
parameter, the message confirming that the utility is
executed is not displayed even if you omit the
-s
parameter.
-r
Specify this parameter when you register, in HDLM, a path that HDLM has not
recognized. When the
dlmcfgmgr
utility is executed, the logical device file of the
HDLM device is created in the
/dev
directory. This enables a user to use an
LDEV of the storage system as an HDLM device.
This parameter is used to create a new HDLM device definition: for example,
when changing the configuration of the storage system (for example, add or delete
an LU), or the host-side hardware configuration.
The path definition information registered in HDLM is inherited even though the
path is disconnected when the host starts.
If the SCSI device of the new path that HDLM detected is already registered (that
is, when the path between the host and an LU of the storage system already exists
and a new path is added), the same HDLM device mapped with the path already
registered is allocated. If the SCSI device of the new path that HDLM detected is
not yet registered (that is, when you define a new path from the host to an LU of
the storage system), the HDLM device with the lowest available letter is allocated
to the path. Examples of allocating a new HDLM device are shown in
Table 7-6: Example: Allocation of New HDLM Devices.
