I have a new R7515 with an HBA330 controller connected to 4x SSDs. The OS is RHEL 8.4.
Under "heavy" load, where "heavy" is just cp -a /some/big/directory /some/other/place, I see many messages like these in the system log:
mpt3sas_cm0: log_info(0x31110e03): originator(PL), code(0x11), sub_code(0x0e03)
This repeats a few times, and is then followed by
sd 0:0:0:0: Power-on or device reset occurred
This message is seen for all 4 drives.
0x31110e03 is by far the most common error code (about 30000 instances so far this month), which this utility says is PL_LOGINFO_SUB_CODE_DISCOVERY_SATA_ERR.
Apart from these log messages, everything seems to be functioning ok, but I would be very grateful for any insight anyone has... Thanks!
What did the support say?
We have an internal SR opened and they keep saying:
"As our global team is still working on it, once I will get update we will inform you."
In our case, we need a true HBA, hopefully the Dell team can find a solution. We use Ubuntu LTS 20.04.
