Hi,
The "cm_storage" schema for the "export_rule" dictionary limits the "clientmatch" to a string of 255 characters. As it is a "certified" dictionary object you can not edit it, you'd have to clone it and create your own datasource. I would advise you raise a support case to ensure a bug (BURT) is raised so WFA engineering may consider increasing the maximum string length in a future release (to match the string length in ONTAP).
In the meantime you might consider generating a report from OCUM to see how widespread the issue is in your environment. EG:
SELECT
cluster.name AS 'cluster_name',
vserver.name AS 'vserver_name',
export_policy.name AS 'export_policy',
export_rule.clientMatch AS 'client_match',
CHAR_LENGTH(export_rule.clientMatch) AS 'rule_length'
FROM
netapp_model_view.export_rule,
netapp_model_view.export_policy,
netapp_model_view.vserver,
netapp_model_view.cluster
WHERE
export_rule.exportPolicyId = export_policy.objid
AND
export_policy.vserverId = vserver.objid
AND
vserver.clusterId = cluster.objid
AND
CHAR_LENGTH(export_rule.clientMatch) >= 255
ORDER BY
rule_length DESC
Once you know the extent of the issue you can determine if automation is required to update the export rules with individual client match values rather than a comma delimited string.
