Before you upgrade HDLM on a NIM client, make sure that your HDLM license
has not expired. If the license has expired, prepare a valid license key or
license key file.
Make sure that the following conditions are met before using the nimadm
command to upgrade HDLM:
• The OS version after migration is AIX 7.1 TL02 SP01, or AIX 6.1 TL08 SP1
or later.
• The target disk of a NIM client used as an alternate disk is in a boot disk
environment.
1. If the HDLM license on the NIM client has expired, renew the license.
If the license has not expired, proceed to step 2.
¢
When only the license key has been provided
On the NIM client, execute the set operation of the HDLM command
while specifying the -lic parameter to enter a license key.
# /usr/DynamicLinkManager/bin/dlnkmgr set –lic
KAPL01049-I Would you like to execute the operation?
Operation name = set [y/n]:y
KAPL01083-I There is no license key file. File name =/var/tmp/
hdlm_license
KAPL01068-I Enter a license key:*************
KAPL01071-I The permanent license was installed.
#
¢
When the license key file has been provided
Store the license key file directly under the /var/tmp/ directory on a
NIM client by using the hdlm_license name.
/var/tmp/hdlm_license
On the NIM client, execute the set operation of the HDLM command
while specifying the -lic parameter.
# /usr/DynamicLinkManager/bin/dlnkmgr set –lic
KAPL01049-I Would you like to execute the operation?
Operation name = set [y/n]:y
KAPL01071-I The permanent license was installed.
#
For details about license key types and the set operation, see
set (Sets
Up the Operating Environment) on page 6-17.
2. Log in to the NIM master as a user with root privileges.
3. On the NIM master, execute the following nimadm command:
# nimadm -c NIM-client-name -l NIM-resource-containing-HDLM -s
NIM-SPOT-name -d NIM-client-target-disk... -Y
For details about the nimadm command, see the AIX documentation.
4. After restarting the NIM client from the alternate disk, execute the
following command on the NIM client to confirm that the package has
been installed:
# lslpp -la DLManager.mpio.rte
