HP XP P9500 Storage - Manual (Page 431)

Applicable operation Inapplicable operation
• Deleting an existing LU (in Solaris
10 and Solaris 11)
• Changing the settings of an existing LU
(changing an LUN mapping or storage
port)
• Deleting a path
• Removing an existing LU from HDLM
management
#
Solaris 8 and Solaris 9 are not supported when a dynamic path is added
because a new HBA was added.
HDLM can use an LU, once it is recognized by the HDLM driver, without
restarting the host. In Solaris 10 or Solaris 11, the HDLM devices for the LUs
that were disconnected from the host can be deleted.
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 Solaris 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,
Solaris 10, or Solaris 11 system.
Format
/opt/DynamicLinkManager/bin/dlmcfgmgr { -a | -h }
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.
