7.3.2 Parameters

-a

Applies the contents of the HDLM driver configuration definition file (

/kernel/

drv/dlmfdrv.conf

) to HDLM driver. The added LU becomes valid after the

command with this option is executed. The HDLM devices for the deleted LUs

become unavailable after the command with this option is executed.

-h

Displays help about the usage of the command.

Examples

Example 1: The

-a

option is specified:

Information on the newly added LUs is applied to the HDLM driver based on the

contents of the HDLM driver configuration definition file (

/kernel/drv/

dlmfdrv.conf

). In Solaris 10, information on the LUs that were disconnected

from the host is deleted from the HDLM driver. In Solaris 8 or 9, information on

LUs that are already managed by HDLM is not updated.


# /opt/DynamicLinkManager/bin/dlmcfgmgr -a

Example 2: Options are omitted:

In this example, the

dlmcfgmgr

utility outputs an error message and displays

help about the usage of the command.


# /opt/DynamicLinkManager/bin/dlmcfgmgr
KAPL10380-E A parameter is invalid.
KAPL10368-I usage: dlmcfgmgr {-a | -h}
#

Note

Execute the

dlmsetconf

utility for creating the HDLM driver configuration

definition file before executing the

dlmcfgmgr

utility.

If you use VxVM, do not use the

dlmcfgmgr

utility. Instead, specify the

reconfiguration option, and then restart the host. To register the HDLM

device to VxVM or cancel the HDLM device registration from VxVM, you

need to restart with the reconfiguration option specified.

The correspondence between the paths and path IDs might differ depending

on whether dynamic reconfiguration of the HDLM device is performed by

executing the

dlmcfgmgr

utility or by restarting the host.
