Aggregate Migration

OmotayoZadok — Fri, 13 Aug 2021 12:24:43 GMT

Is it possible to migrate aggregates from a node that is down to another within the same cluster, considering the fact that the two nodes are an HA pair?
I am not talking about access.

Let's say I created an aggregate and it is owned by one node, and that node goes down. Can I migrate the aggregates from that node to the second node, even while it is down? Please help with procedures or with a link

Thanks!

when one node goes down in a HA-pair configuration, the other node will take over. Part of the takeover is the aggregate relocation, which means that the surviving node will own the aggregate of the node that went down. No intervention required

Additionally, yes you can relocate an aggregate between the nodes of an HA pair: https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.dot-cm-psmg%2FGUID-E7A9B88C-5E4F-4B2B-854D-4549598BE395.html

When one node goes down, the other node automatically takes over and the aggregation relocates. You can refer to the command in the following connectionhttps://docs.netapp.com/us-en/ontap-cli-95/storage-failover-show-takeover.html#parameters
