13 Seeding from a Dell™ DR Series System to an External Device | August 2014
7. To remove the device from the DR Series system to which the seed data has been written, enter
the following command. (It is recommended that you enter the command, seed –stop, before
removing the device.)
seed –remove_device
8. If the data gathering from all the devices is complete, you can enter the following command to
remove the seed job completely.
seed --delete
9. Once the import is complete, replication re-sync must be performed between the source and
target DR Series system containers. Once replication reaches the ‘INSYNC’ state, execute the
following command to remove any data that is left unaccounted from seeding.
Seed –cleanup
3.1 Important notes about the import seeding process
• The order in which the seed devices are attached makes no difference for the seeding process.
• The data at source could have changed after the export process is initiated. This data is replicated
during replication re-sync.
• The command ‘seed –cleanup’ must be executed only after the replication is established between
source and target. If it is executed before, the entire imported data set could be deleted.
• If seeding has to be stopped for any reason, you should enter the ‘seed –stop,’ which will stop all
seeding I/O activity. To continue, enter the command, ‘seed –start’. If an error occurs while reading
the seeding device, you should remove the device using the command, ‘seed –remove_device,’
after stopping the I/O, and then re-attach the device.
• If any device is lost, corrupted, or left unattached during the import process, the data in that particular
device will be received at the time of replication resync and will not have any effect on the import
process.
