blk_update_request: protection error

[fahadshery]

Hi,

I upgraded from SAS2 HBA to SAS3, I can see my drives attached at the start up:


I can also see them without any problems during proxmox installation:


Install goes through fine but I can't access the GUI?? it just times out. why?

I also captured the following before the installer loaded:

What are these errors?
I didn't clean the disks before attaching them with my new backplane and 2 x SAS3 cards. So I deleted the partitions on some of them. But I still see these errors.

These SSDs were working fine without any issues with my previous SAS2 controller.

then I'd blame your new SAS controller

then I'd blame your new SAS controller

I did too but how do you explain the following:

I have 2 identical drives, I was able to remove the type 2 protection from one drive but unable to do it on the second??

Here is what I did:

sg_format --format --size=512 /dev/da2

After the format, it shows this:

sg_readcap -l /dev/da2
Read Capacity results:
   Protection: prot_en=0, p_type=0, p_i_exponent=0
   Logical block provisioning: lbpme=0, lbprz=0
   Last LBA=3516328367 (0xd196e9af), Number of logical blocks=3516328368
   Logical block length=512 bytes
   Logical blocks per physical block exponent=3 [so physical block length=4096 bytes]
   Lowest aligned LBA=0
Hence:
   Device size: 1800360124416 bytes, 1716957.2 MiB, 1800.36 GB

Now if I try to do the same for another drive attached to the same controller, it says its write protected??

sg_format --format --size=512 /dev/da1 -v
    HGST      HUC101818CS4205   NE02   peripheral_type: disk [0x0]
      PROTECT=1

    ALL data on /dev/da1 will be DESTROYED
        Press control-C to abort

Format unit:
Fixed format, current; Sense key: Data Protect
Additional sense: Access denied - no access rights
Format unit command: Data protect, type: sense key; write protected media?
FORMAT UNIT failed

READCAP command still shows this:

sg_readcap -l /dev/da1
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 LBA=3516328367 (0xd196e9af), Number of logical blocks=3516328368
   Logical block length=512 bytes
   Logical blocks per physical block exponent=3 [so physical block length=4096 bytes]
   Lowest aligned LBA=0
Hence:
   Device size: 1800360124416 bytes, 1716957.2 MiB, 1800.36 GB

See the difference??

any other ideas?

might be some sort of interference with the SED (self-encrypting drive) feature - maybe there is some way to reset that via the controller firmware/tools?
