There may be many other alerts as well but all checks prove that these alerts, like the site disconnection alerts mentioned above, appear to be benign.
DR Operations such as Failover or Move as well as Edit VPG may not be possible from the Protected Site.
1) The following SQL queries should be run on each ZVM database in the pair seeing the issue:
NOTE: Kindly follow the typical best practices of backing up each ZVM DB prior to making any edits.
truncate table AlertStateInfoStorageObjectVpgs
2) Then, confirm each table is now clear via the below SQL queries:
select * from AlertStateInfoStorageObjectVpgs
select * from AlertStateInfoStorageObject
3) Monitor the UI to ensure only legitimate alerts are enabled (i.e. you should not see site disconnection alerts after this unless they are actually disconnected).
A fix was implemented into 7.0U1. Hence, upgrading to this code version will avoid this issue from occurring again.
