Cautions When Using ONTAP 9.7 P5
ONTAP 9.7 P5 has an issue with switchless cluster configurations that incorrectly disables the
switchless cluster option when the option to automatically detect switchless clusters is enabled.
If the switchless cluster option is disabled in a switchless cluster configuration, the cluster does not
operate correctly. In this situation, because the controllers cannot communicate with each other
correctly, a controller feedback failure occurs.
Therefore, note the following when using ONTAP 9.7 P5:
(1) Do not change the setting of the option to automatically detect switchless clusters.
Specifically, do not run the following command:
(2) Disable the switchless cluster option after adding a cluster switch.
To disables the switchless cluster option, run the following command:
(3) Contact your Fujitsu maintenance engineer before initializing or setting up a cluster.
When a cluster is initialized or set up while ONTAP 9.7 P5 is running, a workaround must be per-
formed for the issue regarding the switchless cluster option setting. Contact your Fujitsu mainte-
nance engineer for the workaround.
(4)After updating ONTAP to a version without the issue of the switchless cluster option setting,
enable the option to automatically detect switchless clusters.
To enable the option to automatically detect switchless clusters, run the following command:
network options detect-switchless-cluster modify [-enabled] true
network options switchless-cluster modify [-enabled] false
• This command requires advanced privileges to run.
• To check the setting of the switchless cluster option, run the command shown below. This
command also requires advanced privileges to run.
• If a cluster switch is added and later removed, a workaround must be performed for the issue
of the switchless cluster option setting after the cluster switch is removed and the cluster
configuration become switchless. Contact your Fujitsu sales representative, partner sales
representative, or Fujitsu maintenance engineer for the workaround if a cluster switch is to
be added and then later removed.
network options switchless-cluster modify [-enabled] true
network options switchless-cluster show
