Claims31
A method for maintaining a particular disk drive in a storage system, wherein the storage system includes a plurality of disk drives and the particular disk drive that is powered-off, the method comprising:
- powering-on the particular disk drive;
- executing a test on the particular disk drive;
- and
- powering-off the particular disk drive.
A method for maintaining data in a disk drive, the method comprising:
- performing a check on the disk drive;
- and
- if a predetermined criterion is not met as a result of the test then performing a recovery action.
An apparatus for maintaining a particular disk drive in a storage system, wherein the storage system includes a plurality of disk drives and the particular disk drive that is powered-off, the apparatus comprising:
- a power controller for controlling power to the disk drives and the particular disk drive;
- and
- a test-moderator for executing a test on the particular disk drive;
- whereby, the particular disk is powered-on by the power controller before the test is to be executed and the particular disk drive is powered-off after the test is executed.
A machine-readable medium including instructions executable by a processor for maintaining a particular disk drive in a storage system, wherein the storage system includes a plurality of disk drives and the particular disk drive that is powered-off, the machine readable medium comprising:
- one or more instructions for powering-on the particular disk drive;
- one or more instructions for executing a test on the particular disk drive;
- and
- one or more instructions for powering-off the particular disk drive.
An apparatus for maintaining a particular disk drive in a storage system, wherein the storage system includes a plurality of disk drives and the particular disk drive that is powered-off, the apparatus comprising:
- a processor for executing instructions;
- and
- a machine-readable medium including:
- one or more instructions for powering-on the particular disk drive;
- one or more instructions for executing a test on the particular disk drive;
- and
- one or more instructions for powering-off the particular disk drive.
