HDLM-managed device.
You must use the

dlmsetconf

utility for creating the HDLM driver configuration

definition file to modify the configuration of an HDLM-managed device, therefore

you should also see 7.6 The dlmsetconf Utility for Creating the HDLM Driver

Configuration Definition File.

(1) Changing an HDLM-managed Device to a Non-HDLM-Managed Device

To change an HDLM-managed device to a non-HDLM-managed device:
1.

Check the LDEV information of the LU to be removed from HDLM

management.
Use the following command to check the LDEV information:


# /opt/DynamicLinkManager/bin/dlnkmgr view -drv
PathID HDevName Device LDEV
000000 c7t0d0 sd46 9970/9980.15001.066A
000001 c7t0d0 sd47 9970/9980.15001.066A
