Deleting a Path to an Existing LU by Dynamic Reconfiguration
Note
¢
You can delete an LU via dynamic reconfiguration only in Solaris 10 or
Solaris 11.
¢
If SVM is used for the volume manager, delete the path to the HDLM
device and then execute metaclear for SVM to delete the disk. Then,
execute metainit to re-create the disk.
¢
If VxVM is used for the volume manager, delete the path, execute the
dlmvxexclude utility, and then perform a reboot.
¢
Only data disks can be reconfigured dynamically. You cannot change
the configuration of boot disks.
¢
If paths are dynamically added or deleted from an existing LU, then
you cannot delete all paths to that existing LU.
This section describes how to dynamically delete a path to an existing LU.

.
Configure the storage system, switch, or other device to disconnect from
the host. To disconnect from the existing path, perform the following
operations.
¢
Set up the storage system (remove the mapping between the internal
LU and the storage port LUN).
¢
Terminate the connection between the storage port and the host HBA
port.
¢
Release the Fibre Channel switch settings.
¢
Release the settings for the host HBA and for the sd or ssd driver.
For details on how to perform these settings, see the documentation of
the HBA being used. You may need to restart the host, depending on the
HBA being used, its drivers, and the path configuration of the deleted LU.

.
Execute the dlmsetconf utility for creating the HDLM driver configuration
definition file and then update the HDLM driver configuration definition file
(/kernel/drv/dlmfdrv.conf).
# /opt/DynamicLinkManager/bin/dlmsetconf
If an error message or warning about the deleted path is issued, ignore
the message. In addition, see the /opt/DynamicLinkManager/config/
dlmfdrv.unconf file to check that the file does not contain information
