7.6 The dlmsetconf Utility for Creating the HDLM Driver

Configuration Definition File

This

dlmsetconf

utility obtains device information retained by Solaris, and defines

the storage system's sd or ssd device entries in the HDLM driver configuration

definition file (

/kernel/drv/dlmfdrv.conf

) and the HDLM nexus driver

configuration definition file (

/kernel/drv/dlmndrv.conf

).

The sd or ssd device entries are sorted in ascending order of the LDEV information

(for example, 9970/9980.15001.066A).
If an existing HDLM driver configuration definition file (

/kernel/drv/

dlmfdrv.conf

) is available, the existing definitions are inherited. If an existing

HDLM nexus driver configuration definition file (

/kernel/drv/dlmndrv.conf

) is

available, the existing definitions are inherited. An HDLM driver unconfiguration

definition file (

/opt/DynamicLinkManager/config/dlmfdrv.unconf

) is

created.
All HDLM-managed devices are defined in the HDLM driver unconfiguration

definition file (

/opt/DynamicLinkManager/config/dlmfdrv.unconf

). The

devices in the file are managed in units of LUs and begin with a hash mark (#) as

comment lines. When you want to specify that a device is not to be managed by

HDLM, use a text editor to edit the HDLM driver unconfiguration definition file (

/

opt/DynamicLinkManager/config/dlmfdrv.unconf

) and remove the

comment-out status in the LDEV line (that is, delete

#

at the beginning of the line).

When you want to specify that a disk not managed by HDLM is to be managed by

HDLM, use a text editor to edit the HDLM driver unconfiguration definition file (

/

opt/DynamicLinkManager/config/dlmfdrv.unconf

) and then comment out

the LDEV line (that is, add # at the beginning of the line). In either case, do not make

any changes to the file except for adding or deleting

#

at the beginning of the LDEV

line.
When the configuration of the storage system is modified (for example, when LUs are
added or deleted, or when the default controller is changed

#

) or when the hardware

configuration on the host side is modified, it is necessary to execute the

dlmsetconf

utility, and then use one of the following commands to restart the host in order to

reconfigure the devices. The HDLM devices are reconfigured.

# reboot -- -r
At the ok prompt, execute the following:
boot -r

#

Specifying the

-r

option is not required when only the default controller is

changed.
