Someone else suggested off-list that this might be the LSI HBA controller running its "partrol" of the disks in the system. Our HBA model is: Avago Technologies (LSI) SAS3008 We're using the mpr drive, but mprutil doesn't seem to have any way to query or set the status of the "patrol" function. I rebooted the machine into the BIOS config for the HBA, but could not find any reference to enabling or disabling "patrol" there either. Am I missing something? Does this adapter actually do any patrolling? I did notice that all the drive activity lights are lit on this server nearly all the time, but I can't tell if that means "activity" or "on-line" for that controller in a SuperMicro chassis. -- Tim Gustafson BSOE Computing Director tjg@ucsc.edu 831-459-5354 Baskin Engineering, Room 313A To request BSOE IT support, please visit https://support.soe.ucsc.edu/ or send e-mail to help@soe.ucsc.edu.
