7.3 The dlmcfgmgr Utility for Managing the HDLM Configuration
This utility makes the HDLM driver recognize the contents of the HDLM driver
configuration definition file (
/kernel/drv/dlmfdrv.conf
) dynamically without
restarting the host. Table 7-2: Configuration Changes Applicable and Not Applicable
to the dlmcfgmgr Utility for Managing the HDLM Configuration illustrates the
configuration changes applicable and not applicable to the
dlmcfgmgr
utility for
managing the HDLM configuration.
Table 7-2: Configuration Changes Applicable and Not Applicable to the
dlmcfgmgr Utility for Managing the HDLM Configuration
Once an LU is recognized by the HDLM driver, HDLM can use the LU without
restarting the host. In Solaris 10, you can delete the HDLM devices for the LUs that
were disconnected from the host.
If the definition of the HDLM driver configuration definition file (
/kernel/drv/
dlmfdrv.conf
) has been changed due to configuration changes such as deleting LUs
or changing or deleting paths (in Solaris 8 or 9), or by changing or deleting paths (in
Solaris 10), then these changes are not applicable to the the
dlmcfgmgr
utility and are
not reflected in the HDLM driver. Restart the host with the reconfiguration option
specified, and then change the configuration.
Executing the
dlmcfgmgr
utility outputs the KAPL10373-I message. Entering
y
in
response to this message performs dynamic reconfiguration of the HDLM devices,
deletes the logical device files for the sd or ssd devices managed by HDLM, and then
deletes the logical device files for the HDLM devices which correspond to the LUs
deleted from HDLM management. Also, the detailed information is output to the
/
var/opt/DynamicLinkManager/log/dlmcfgmgr1.log
. Entering
n
in response
to this message cancels the dynamic reconfiguration processing.
The
dlmcfgmgr
utility is valid in Solaris 8 version 1/01 or later, Solaris 9, or Solaris
10 system.
