22. A maintenance controller for a data storage system having a plurality of trays, each tray comprising a module having an array of data storage disks, the maintenance controller being configured to:
- as preparation for taking the first module off-line, transfer data stored on data storage disks of a first module to data storage disks of a second module;
take the first module off-line from the data storage system to enable the data storage disks of the first module to be serviced; and
put the serviced first module back online.
- as preparation for taking the first module off-line, transfer data stored on data storage disks of a first module to data storage disks of a second module;
