HP XP P9500 Storage - Manual (Page 315)

Note
Before executing the dlmrmdev utility, stop all processes and services using
the paths managed by HDLM. If you execute the dlmrmdev utility without
stopping the processes and services that are using the paths managed by
HDLM, hdisks recognized as HDLM management-target devices might not be
deleted completely or changed to the Defined status
Examples
In the following example, the utility unmounts the file system used by HDLM,
inactivates the volume group used by HDLM, and deletes all the hdisks
recognized as HDLM management-target devices:
# /usr/DynamicLinkManager/bin/dlmrmdev -A
KAPL10528-I The volume group will be made inactive, and the file
system that is using HDLM will be unmounted. Is this OK? [y/n]:y
hdisk3 is deleted
KAPL09012-I All HDLM drivers were removed.
In the following example, the utility displays Help:
# /usr/DynamicLinkManager/bin/dlmrmdev -h
Usage : dlmrmdev [[-e | -f] [-A [-s]] | -h]
