scsi error at SEAGATE ST1200MM0088 TT31

[geoffroy desvernay]

Sorry for the 'me too' style, I won't bring a response here… But it
seems there is something to catch here, I'm just adding my case's details:

These "ILLEGAL REQUEST asc:20,0" seems identical to the thread 'mpr(4)
bug ?' (2016/12/12) this wasn't a mpr(4) bug.

Same symptoms: disks seems ok, but real use fails… Now trying to
"sg_format" them… to be continued …

Here we have 24 SEAGATE ST2000NX0433 NS02 drives in a md1420 enclosure
connected via a sas3008 adapter. Setup tested working with debian 8 and
centos 7.

sg_readcap --16 returns:
Read Capacity results:
   Protection: prot_en=1, p_type=1, p_i_exponent=0 [type 2 protection]
   Logical block provisioning: lbpme=0, lbprz=0
   Last logical block address=3907029167 (0xe8e088af), Number of logical
blocks=3907029168
   Logical block length=512 bytes
   Logical blocks per physical block exponent=0
   Lowest aligned logical block address=0
Hence:
   Device size: 2000398934016 bytes, 1907729.1 MiB, 2000.40 GB

Yours,
