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
• Adding a new LU
• Managing the LU that has been
removed from HDLM management
• Deleting an existing LU (in Solaris
10)
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.
