4260 Storage partition migration is paused. User action is required.

Explanation

This error gets raised in the following scenarios:

Event ID 051421
This event gets raised at source system after a rollback operation is triggered at target system possibly due to any host, performance, or other issues observed on the target system.
Event ID 051015
This event gets raised at the target system for hosts that do not support auto storage discovery. Trigger rescan of the target IO path on the host before you fix the event.
Event ID 051021
This event gets raised when the migration is complete, and user is in a position to provide consent for deleting the source copy at source system. This is the final point to rollback or cancel the migration procedure. Before proceeding to fix this event, you should perform the following checks:
  • Verify the host's multipath configurations.
  • Ensure the path availability and redundancies.
  • Assess IO performance at the Target System.

User response

Perform the following actions to fix the respective event:
For Event ID 051421

If you have fixed the issues on the target cluster, use the following command to continue the migration:

chpartition -migrationaction fixeventwithchecks <partition_id>

This continues the migration procedure from source system.

If you do not want to migrate, use the following command to delete the target copy of the storage partition:

chpartition -override -location <source_system> <partition_id>

This confirms that the rollback was triggered earlier and the migration operation is canceled.

For Event ID 051015

If you want to continue with the migration on the target system, use the following command after triggering rescan on the host:

chpartition -migrationaction fixeventwithchecks <partition_id>
If the host issues are known (in scenarios where the hosts are known to be down or to load balance partitions across the systems), use the following command to force the migration, skipping the host validations at the target system:
chpartition -migrationaction fixeventskipchecks <partition_id>
If you do not want to continue the migration or need some time to fix the host and networking issues on the target and reattempt the migration at a later point, use the following command to trigger the rollback operation at the target system:
chpartition -override -location <source_system> <partition_id>
For Event ID 051021
If you are satisfied with the storage partition migration and want to delete the source copy by giving consent to commit the migration, use the following command to complete the migration procedure:
chpartition -migrationaction fixeventwithchecks <partition_id/name>
If you do not want to continue the migration or need some time to fix the host and networking issues on the target and reattempt the migration at a later point, use the following command to trigger the rollback operation at the target system:
chpartition -override -location <source_system> <partition_id>
