Pausing/resuming a batch migration (optional)
Active batch migrations (a migration that has been started) can be paused and resumed.
About this task
Pause an active batch migration to release bandwidth for host I/O during periods of peak traffic.
Resume the batch migration during periods of low I/O.
Use the batch-migrate pause command to pause the specified active migration. For example:
VPlexcli:/data-migrations/device-migrations> batch-migrate pause --file migrate.txt
Use the batch-migrate resume command to resume the specified paused migration. For example:
VPlexcli:/data-migrations/device-migrations> batch-migrate resume --file migrate.txt
Canceling a batch migration (optional)
Cancel an active batch migration to return the source volumes to their state prior to the start of the migration.
About this task
Use the batch-migrate cancel command to cancel the specified migration. For example:
VPlexcli:/data-migrations/device-migrations> batch-migrate cancel --file migrate.txt
NOTE:
In order to re-run a canceled migration plan, use the batch-migrate remove command to remove the records
of the migration. See Removing batch migration records.
Monitoring a batch migration’s progress
Use the batch-migrate summary command with the --verbose option to monitor the progress of the specified batch
migration:
