FWIW, we performed the same test with the AOC-S3816L-L16iT [1], shown in
lspci as:
85:00.0 Serial Attached SCSI controller [0107]: Broadcom / LSI Fusion-MPT 12GSAS/PCIe Secure SAS38xx [1000:00e6]
Subsystem: Super Micro Computer Inc AOC-S3816L-L16iT (NI22) Storage Adapter [15d9:1b65]
Kernel driver in use: mpt3sas
Kernel modules: mpt3sas
If I understand the Broadcom website correctly, this one is not EOL? It has
Lifecycle Status "Active" [2].
Firmware is reported as:
kernel: mpt3sas_cm0: FW Package Ver(33.00.00.01)
kernel: mpt3sas_cm0: SAS 3816: FWVersion(33.00.00.00), ChipRevision(0x00)
Also here, hotplug fails with the following message:
kernel: mpt3sas_cm0: handle(0x001a), ioc_status(0x0022) failure at drivers/scsi/mpt3sas/mpt3sas_transport.c:225/_transport_set_identify()!
As in all the previous tests, the hotplugged disk is a SAS disk (as
discussed in [4]).
This time we tried to collect debug logs:
echo 0xfffff > /sys/module/mpt3sas/parameters/logging_level
As expected, the logs are quite verbose, but I think the following is the
relevant portion. If a bigger excerpt would be helpful, please let me know.

I think this is scsi_cdl_check's first RSOC command scsi_cdl_check_cmd(sdev,
READ_16, 0, buf)?

Compare with hotplug on a kernel with [3] applied (which disables the CDL
