Re: Intel Optane SSD mounting problem

Hi Tom, Colin,
I'm running Ubuntu 20.04 LTS (kernel: 5.4.0-37-generic) and compiled DAOS v1.0.0.
I also compiled the latest master as of yesterday, but it did not make a difference.
Any application that can manage Opal 2.0 can be used to check the status of the drive. I used the sedutil-cli, can be found at https://github.com/Drive-Trust-Alliance/sedutil the executable can be found at https://github.com/Drive-Trust-Alliance/sedutil/wiki/Executable-Distributions
You can run
# sedutil-cli --scan
# sedutil-cli --query <device>
it will return useful information about the Opal status of the device.
sedutil-cli will send NVMe security commands and the tool will only work if your SSD is bound the the NVMe driver.
In case the SSD is not bound to the NVMe driver you can manage the drive with the nvme_manage spdk utility you can found in the /daos/_build.external/dev/spdk
Select 8 to get into the OPAL NVMe Management Options, enter the PCIe address of your SSD for the list you get prompted, select 1 to scan the device. These steps gives you the same results as running the # sedutil-cli --query <device> in case the SSD is bound to the NVMe driver.
