Intel P3600 can't format between LBAFs

[NQuig]

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.

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 -

- Byte 0-7 -

Namespace Size : 781422768

- Byte 8-15 -

- Byte 16-23 -

Namespace Utilization : 781422768

Bit 7:5 - Reserved : 0

Bit 4 - Metadata transfer bit : 1

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!

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

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

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
