[SPDK] Re: Error creating block device based on NVMe device

Hi Ye,

The OPAL error message showed that your drive can support Security send/receive commands but can't support OPAL, it doesn't affect anything, so the block device was created successfully.

Could you submit a github issue for the Segment Fault, it's better to include the calltrace, I can take a look. Thanks.
