Delay on battery learn cycle is not working due to a problem in the firmware conversion. Learn cycle is a battery calibration operation performed by the PowerEdge RAID Controller (PERC) every 90 days to determine the condition of the battery. By design, this operation can be delayed (up to 7 days) by the user through OpenManage Storage Service (OMSS). Dell engineering has identified that due to a problem in the firmware where conversion for learn delay value (hour<->seconds) is not handled correctly, hence the delay is not working.
The issue applies to the current shipping PERC5 firmware 5.2.2 and PERC6 firmware prior to version 6.1.1.
Issue was corrected in PERC6 firmware 6.1.1 release.
The issue is still present in PERC5 firmware 5.2.2.
