Cautions after Upgrading ONTAP
If ONTAP is upgraded to the following versions or later, delete the ONTAP image used for the
upgrade.
• ONTA 9.11.1 P8
• ONTAP 9.12.1 P2
• ONTAP 9.13.1 GA
In the upgrade status confirmation (performed in the API/CLI) process after upgrading to the above
versions, the ONTAP image used for the upgrade may be mounted multiple times in systemshell and
may cause nodes to stop.
The following procedure can be performed to determine whether multiple mounts are occurring.
1 Change to the Diag mode.
2 Execute df in systemshell.
Notes on Reverting the Firmware
• To revert the firmware, the general rule is to make sure Fujitsu Support is contacted.
Refer to "ETERNUS AX/HX series Upgrade and Revert/Downgrade Guide" for more details.
• The ONTAP version cannot be reverted to ONTAP 9.10.1 or earlier if a file is set using SnapLock
with a retention time later than January 19, 2071 at 8:44:07 am.
set -priv diag
system node systemshell -node nodename -command "df -ik"
• If multiple mounts have occurred, multiple mount points will be displayed under /mroot/etc/
NDU/mnt/store.
• The increase in multiple mounts can be stopped by deleting the ONTAP image used for the
upgrade.
Example:
cluster image package delete -version 9.12.1P2
• Multiple mounts can be deleted using the takeover/giveback operation on the relevant node.
