Cautions When Using ONTAP Versions 9.11.1 to 9.11.1 P2
• In ONTAP versions 9.11.1 to 9.11.1 P2, the following problems may occur when the FabricPool/
Cloud Volumes ONTAP (CVO) function is used.
Use the FabricPool/CVO function in ONTAP version 9.11.1 P3 or later. ONTAP 9.11.1 P3 is planned
for release at a later time.
- A FabricPool operation fails
- Creating an aggregate fails in Cloud Manager
- A failure occurs in replications that use SnapMirror between CVOs
- A Multi-Disk Panic (MDP) occurs in an environment deployed on Azure
- The Tiering dashboard of Cloud Manager displays an error
• In ONTAP versions 9.11.1 to 9.11.1 P2, disable cluster peer encryption for newly created cluster
peers.
Example:
Cautions When Using ONTAP 9.12.1
• ONTAP 9.12.1 has a command option that can force automatic switchover even when MetroClus-
ter is configured and the NVRAM is not synchronized (metrocluster modify -allow-auto-forced-
switchover).
If this option is used when the unsynchronized area in the NVRAM contains write data, the write
data between clusters will become inconsistent. Therefore, do not use this option if a risk of cor-
ruption or loss of write data is not acceptable.
• In ONTAP 9.12.1, do not set the default retention period (-default-retention-period) of SnapLock
volumes to "unspecified".
Cautions When Using ONTAP 9.12.1/ONTAP 9.13.1
• ONTAP 9.12.1 and ONTAP 9.13.1 do not support conversions to FlexGroups or FlexGroup rebal-
ancing for the following volumes:
- Volumes that are migrated from 7-Mode and have non-Unicode names
• ONTAP 9.13.1 does not support NDMP restores to a primary cluster volume (*1) in the following
environment:
- SnapMirror-BC environment or SnapMirror-Sync environment
- The ONTAP version of the primary cluster is ONTAP 9.13.1
- The ONTAP version of the secondary cluster is ONTAP 9.13.1 P2 or later
*1: NDMP restore is supported if ONTAP 9.13.1, or ONTAP 9.13.1 P2 or later version is running on both the
primary cluster and secondary cluster.
• Do not create a file in a directory that has a level of 500 or lower for the following ONTAP ver-
sions. Creating such a file may cause a node to stop.
- ONTAP version: 9.12.1 P4 to 9.12.1 P7
- ONTAP version: 9.13.1 to 9.13.1 P5
