management-target devices from the running kernel, and then stop the HDLM
manager:
# /usr/DynamicLinkManager/bin/dlmrmdev
The
KAPL09012-I
message appears.
If the
KAPL09012-I
message is not displayed, the HDLM driver has not been
deleted, or the HDLM manager has not stopped. Make sure that no process,
service, file system, or volume group is using the HDLM management-target
path, and then re-execute the above command.
15. Execute the following command to make sure that the hdisk recognized as the
device to be managed by HDLM has been deleted:
# lsdev -Cc disk
16. Execute the HDLM pre-uninstall utility
dlmpreuninst
.
# /usr/DynamicLinkManager/bin/dlmpreuninst
If you execute the
dlmpreuninst
utility, the hdisk recognized as a boot disk
stops being the HDLM's management target. When the command terminates
normally, the following message appears:
KAPL13103-I HDLM can be uninstalled after rebooting the host.
KAPL13101-I The dlmpreuninst utility completed successfully.
