3. Creating an HDLM Environment
246
storage system. This information will enable you to keep the correspondence with
the logical device file names after HDLM has been uninstalled.
You can collect this correspondence information by outputting the results of the
dlnkmgr
command's
view -path
operation to a file. The following shows an
example of executing the command:
# /opt/DynamicLinkManager/bin/dlnkmgr view -path > /var/tmp/
old_view_path_list.txt
Note
Do not specify any of the directories shown below as the output destination
of the results of the
dlnkmgr
command's
view -path
operation. If you
specify one of these directories, the file will be removed when you uninstall
HDLM.
-
/opt/DynamicLinkManager
-
/opt/hitachi
-
/var/opt/DynamicLinkManager
-
/var/opt/hitachi
3. Back up the logical device files within the
/dev/dsk
,
/dev/rdsk
directories to
another directory.
The following shows an example of executing the commands:
# mkdir /var/tmp/bkfile2
# ls -l /dev/dsk > /var/tmp/bkfile2/devices1
# ls -l /dev/rdsk > /var/tmp/bkfile2/devices2
4. Stop all processes and services that are using HDLM-managed paths.
Stop all processes and services of DBMS and other applications that are using
HDLM-managed paths.
5. Unregister the HDLM-managed devices.
If HDLM-managed devices are registered with applications, including cluster
software programs (other than Volume Manager), unregister those devices. Since
HDLM-managed devices are accessed by using the logical device file names of
the HDLM devices, these applications will no longer be able to access those
HDLM-managed devices by using the names currently used.
6. Use the following command to unmount all mount points that are using HDLM:
# umount
mount-point
