Reset MegaCLI error count

dell-percmegaclimegaraid

I have a system where MegaCli64 -PdList -a0 shows media errors on one disk. After investigating the errors, I've decided not to take any action for now. I'd like to reset the error count, so that MegaCli will show 0 media errors unless there is another error. What arguments to MegaCLI do I need to do this?

AFAIK there is no way to clear those errors besides replacing the disk and rebuilding the raid set with a healthy disk =/. I tried running MegaCli64 -h but could not find anything for clearing them

It's the number of SMART errors on the physical disk.

MegaCLI causes drive “Other Error”

Regarding why it is happening, it appears that that version of the MegaCli software issues commands unsupported by SATA drives. You can verify this by obtaining the controller event log:

MegaCli64 -AdpEventLog -GetLatest 100 -f events.log -aALL

After execution, an events.log file will contain the controller error events. If indeed the cause is unsupported commands issued to the drive, your error events should look something like:

Event Description: Unexpected sense: PD 07(e0x20/s7) Path 1221000007000000, CDB: 4d 00 4d 00 00 00 00 00 20 00, Sense: 5/24/00

The sense code of 5/24/00, according to this table of common codes, is "Illegal Request - invalid field in CDB (Command Descriptor Block)".
