Applies to

  • Clustered Data ONTAP 8.3 and later introduced Network IP Spaces
  • The maximum supported number of IP spaces for cluster with nodes containing less than or equal to 6g of memory is 256 IP spaces.
  • The maximum supported number of IP spaces for all other clusters containing only nodes with greater than 6g of memory is 512 IP spaces.

Issue

Check Active IQ if this impacts your systems.

The maximum number of IP Spaces for clustered Data ONTAP cluster has been exceeded. This can lead to performance issues and incomparability with later versions of Data ONTAP. This should be addressed as soon as possible.

First, run the sysconfig -A command to determine how much memory each of your nodes in the cluster has:
Example:

cluster1::> run -node * sysconfig -A

If any node in the cluster has less than or equal to 6144 MB of memory, then the limit of IP Spaces is 256.
If all nodes in the cluster have more than 6144 MB of memory, then the limit is 512 IP Spaces.

You can determine how many IP Spaces you have on the cluster by running the network ipspace show command.
Example:

cluster1::> network ipspace show
