SCSI Physical Drive Statistics Preservation Method. This value indicates how all of the objects in this table are saved over a power cycle. If the objects are not saved then all of their values will be reset whenever the device driver is unloaded. The following values are defined: other(1) The agent does not recognize the status. You may need to upgrade your software. inNVRAM(2) The objects are saved in non-volatile memory in the computer system. onDisk(3) The objects are saved on the physical drives in reserved sectors. noCPUSupport(4) The objects are not saved across power cycles because the hardware does not support this operation. noFreeNVRAM(5) The objects are not saved across power cycles because all of the available non-volatile memory is in use. noDrvSupport(6) The objects are not saved across power cycles because the physical drive does not contain a unique identifier to save it under. noSoftwareSupport(7) The objects are not saved across power cycles because either the device driver or computer system firmware do not provide support. statsNotSupported(8) Drive statistics are not supported.
