DRT = Data Retention Time
Transparent and Shorter Learn CyclesThe battery learn cycle is the process
where MegaRAID firmware recalibrates the bat-tery gas gauge with respect to the battery’s chemical capacity
so that controller can decide whether or not the battery can maintain the controller cache for the selected period of time (DRT) in the event of a power failure.
The battery learn cycle partially discharges and then fully charges the battery backup unit.

sg_logs
access log pages with SCSI LOG SENSE command
This utility sends a SCSI LOG SENSE command to the DEVICE and then outputs the response.
The LOG SENSE command is used to fetch log pages.
Known log pages are decoded by default. When the --reset and/or --select option is given then a SCSI LOG SELECT command is issued to reset parameters.
