HP XP7 Storage - Manual (Page 173)

Note:
When you are executing the dlnkmgr command's set operation with the -
lic parameter to install the license, you can only execute it once at a
time. If you attempt to execute more than one dlnkmgr command
containing the set operation with the -lic parameter, the following
message might appear and HDLM might terminate abnormally:
KAPL01075-E A fatal error occurred in HDLM. The system
environment is invalid.
If this message appears, execute the dlnkmgr command's view operation
with the -sys -lic parameter to make sure that the license is installed
correctly.
The following shows an example in which the command is executed:
PROMPT>dlnkmgr set -lic
KAPL01049-I Would you like to execute the operation? Operation name
= set [y/n]: y
KAPL01071-I A permanent license was installed.
