Deleting an LU via Dynamic Reconfiguration
Note
¢
You can delete an LU via dynamic reconfiguration only in Solaris 10 or
Solaris 11.
¢
You cannot delete an LU via dynamic reconfiguration if that LU is
being used by an upper-level application.
¢
You cannot delete only some of the paths to an LU; all paths must be
deleted at one time.
To delete an LU managed by HDLM:
1
.
Stop any programs that are using the LU that you want to delete.
2
.
Set up the storage system and switch to cut the connection between the
host and LU.
Perform the following operations to cut the connection to an existing LU:
¢
Set up the storage system (release the mapping between the internal
LU and the storage port LUN)
¢
Cut 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, refer to the documentation
for 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 to update the HDLM driver configuration definition file (/
kernel/drv/dlmfdrv.conf).
# /opt/DynamicLinkManager/bin/dlmsetconf
If an error message or warning message is displayed for the deleted LU
path, ignore it. In addition, refer to the file /opt/DynamicLinkManager/
config/dlmfdrv.unconf to make sure that the file does not contain this
LU and also contains an LU other than this one.
