Cluster administration

To manually migrate the cluster resources from one node to another, run the following command:

prihana:~ # crm resource move rsc_SAPHana_HDB_HDB00 force INFO: Move constraint created for rsc_SAPHana_HDB_HDB00 to sechana

Check the status of the migration using the command “crm_mon –r”.

prihana:~ # crm_mon -r Stack: corosync Current DC: prihana (version 1.1.18+20180430.b12c320f5-3.24.1-b12c320f5) - partition with quorum Last updated: Thu Nov 12 12:39:00 2020 Last change: Thu Nov 12 12:38:47 2020 by root via crm_attribute on prihana 2 nodes configured 6 resources configured Online: [ prihana sechana ] Full list of resources: res_AWS_STONITH (stonith:external/ec2): Started prihana res_AWS_IP (ocf::suse:aws-vpc-move-ip): Started sechana Clone Set: cln_SAPHanaTopology_HDB_HDB00 [rsc_SAPHanaTopology_HDB_HDB00] Started: [ prihana sechana ] Master/Slave Set: msl_SAPHana_HDB_HDB00 [rsc_SAPHana_HDB_HDB00] rsc_SAPHana_HDB_HDB00 (ocf::suse:SAPHana): Promoting sechana Slaves: [ prihana ]

After the resource is migrated, you can check the status of the cluster. Clean up the failed actions as shown in next section.
