ONTAP version: 9.8P1
Windows version: 2012 (R2?)
Background:
- existing FAS8020 has had A220 added to the cluster
- planning vol moves from FAS8020 to A220
- majority of existing LUNs on FAS8020 had no reporting nodes
Action:
- on all LUNs:
- ran a 'lun mapping add-reporting-nodes -path <lun path> -igroup <igroup> -vserver <vserver> -destination-aggregate <new node aggregate>
- ran a 'lun mapping add-reporting-nodes -path <lun path> -igroup <igroup> -vserver <vserver> -local-nodes true
Problem:
- Customer reported that their Windows 2012 server databases were going down
- Servers dropped the mapped iscsi disk
- BUT all target connections still showed as up in the iSCSI initiator properties
Questions:
- Any ideas as to what might have happened?
- Any pointers to documentation that might help with why it happened?
So far, all we can come up with is: "that's just windows" - but it's not something I can go back to the customer with!
Thank you all in advance.
