(such as this upgrade) to the file systems.
Be sure that all 04.40-/B prerequisite conditions are met before proceeding
with the upgrade.
Halt all activity with the file systems for the duration of the upgrade.
Versions older than 04.02 must be uninstalled before you install version
04.40. This includes removing the /opt/hitachi/HNTRLib files. Check the
Auto Path for AIX User Guide for steps to uninstall the older version.
For versions 04.02 or later, it is not necessary to uninstall the previous
version of Auto Path.
To upgrade:
1. Unmount all Auto Path file systems.
2. Deactivate all Auto Path (HDLM) volume groups.
Example
# dlmvaryoffvg dlmvg01
3. Save the dlmfdrv.conf or dlmfdrv.unconf file to a safe place.
Example
# cp /usr/DynamicLinkManager/drv/dlmfdrv.conf /tmp
4. Remove the Auto Path devices created with the previous version:
# dlmrmdev
5. Ensure that the fscsin attribute fc_err_recover is set to fast_fail.
Perform the following steps if needed:
a. This step removes the fscsi device and all of the hdisk definitions
that are associated with this path. Record the LUN associations
before proceeding so you can verify that the hdisk definitions
correspond to the volume group definitions.
# rmdev -l fscsin -R
