Intel P3600 can't format between LBAFs

NQuig — Tue, 18 Oct 2016 14:26:36 GMT

I have an Intel P3600 drive formatted to LBAF=2 (lbaf 2 : ms:16 ds:9 rp:0x2 (in use)). I can no longer format to different LBAFs. Drive FW is 8DV101F0, which I believe is the latest. This persists across reboots, power cycles, etc.

NickQuigley,

Considering the information you have sent us, could you please try to format it by using the following tool:https://downloadcenter.intel.com/download/26221/Intel-SSD-Data-Center-Tool?product=87278 Intel® SSD Data Center Tool and execute the NVMe* format stating on page # 39 through # 42 of this guide: http://www.intel.com/content/dam/support/us/en/documents/solid-state-drives/ssd-software/Intel_SSD_DCT_3_0_x_User_Guide.pdf Intel® Solid State Drive Data Center Tool - User Guide Let us know if this helped you.Best regards,Aleki

Hi Aleki,

This didn't address the issue. Here is the identify namespace info showing that we are using LBAF=2

[root@vlun200 ~]# isdct show -identify -namespace 1 -intelssd 0

- Identify Namespace CVMD449200B7400FGN -

I then do the format to LBAF=0

[root@vlun200 ~]# isdct start -intelssd 0 -nvmeformat LBAFormat=0 ProtectionInformation=0

WARNING! You have selected to format the drive!

But after the format, the namespace still uses LBAF=2

NickQugley,

Thank you for the clarification. In this particular case we are going to engage additional resources to address this situation. In the mean time, please let us know if there any other piece of relevant information you would like to share.Best regards,Aleki

NickQuigley,

Thank you for your time. Could you please confirm that this drive is attached to the board or are you using something else such as a RAID controller? If so, could you please be so kind and use it directly on the board and trey a secure erase?Please let us know the results as soon as you can.Best regards,Aleki

Aleki,

Yes, this drive is directly attached to the board. Secure Erase didn't help:

Before Secure Erase:

[root@VLUN127 Drive FW]# isdct show -identify -namespace 1 -intelssd 0

Secure Erase:

[root@VLUN127 Drive FW]# isdct start -intelssd 0 -nvmeformat SecureEraseSetting=1

WARNING! You have selected to format the drive!

Proceed with the format? (Y|N): y

Formatting...

Format to LBAF=0:

WARNING! You have selected to format the drive!

Proceed with the format? (Y|N): y

Check again, and we are still at LBAF=2

NickQuigley,

Thank for the report, based on this, could you please be so kind run the tool found in this link: https://github.com/linux-nvme/nvme-cliFollow the steps found in this very website so you can use it to install the source for the distribution you intend to use. Use the command to format found in this link: https://github.com/linux-nvme/nvme-cli/blob/master/Documentation/nvme-format.txtHere is an example nvme format /dev/nvme0n1 and check the LBAF is set to 0.Let us know if this helped you,Best regards,Aleki

Aleki,

This did not help either:

[root@vlun118 ~]# nvme id-ns /dev/nvme1n1 -n 1 | grep lbaf

nlbaf : 6

lbaf 0 : ms:0 ds:9 rp:0x2

lbaf 1 : ms:8 ds:9 rp:0x2

lbaf 2 : ms:16 ds:9 rp:0x2 (in use)

lbaf 3 : ms:0 ds:12 rp:0

lbaf 4 : ms:8 ds:12 rp:0

lbaf 5 : ms:64 ds:12 rp:0

lbaf 6 : ms:128 ds:12 rp:0

[root@vlun118 ~]# nvme format /dev/nvme1n1 -n 1 -l 0 -i 0

Success formatting namespace:1

[root@vlun118 ~]# nvme id-ns /dev/nvme1n1 -n 1 | grep lbaf

nlbaf : 6

lbaf 0 : ms:0 ds:9 rp:0x2

lbaf 1 : ms:8 ds:9 rp:0x2

lbaf 2 : ms:16 ds:9 rp:0x2 (in use)

lbaf 3 : ms:0 ds:12 rp:0

lbaf 4 : ms:8 ds:12 rp:0

lbaf 5 : ms:64 ds:12 rp:0

lbaf 6 : ms:128 ds:12 rp:0

Would it be helpful to RMA one of the drives exhibiting this behavior? This is being done in an engineering/QA environment so we would be open to returning a drive on an RMA if it helps root cause the issue.
