Re: Intel Optane SSD mounting problem

Lombardi, Johann
Hi Patrick,
I talked to the SPDK folks and they suggested to try removing line 1464-1470 in module/bdev/nvme/bdev_nvme.c:
- if (spdk_nvme_ctrlr_get_flags(nvme_bdev_ctrlr->ctrlr) & - SPDK_NVME_CTRLR_SECURITY_SEND_RECV_SUPPORTED) { - nvme_bdev_ctrlr->opal_dev = spdk_opal_dev_construct(nvme_bdev_ctrlr->ctrlr); - if (nvme_bdev_ctrlr->opal_dev == NULL) { - SPDK_ERRLOG("Failed to initialize Opal\n"); - } - }
Could you please give this a spin?
Cheers, Johann

Gert,
Thanks for the further information. Something I don't quite follow:
Then, can Opal be enabled? Or is it permanently disabled on this model?
A general question for you:
Separately, I'm going to dig a little, and I also plan to try older versions of DAOS/SPDK to see what I can figure out.

Patrick, Colin,
I verified with the NSG Business Unit that builds the 905P SSD. The product specification lists both Pyrite as Opal support, what is less clear in the documentation is that Opal is not enable. This is causing the behavior you are seeing. The Identify command correctly returns the Security Send/Receive is supported as this is needed for both Opal and Pyrite. It is correct that SPDK returns “No Opal support” for the 905P SSD. I verified on my system you do not have this with the Intel Optane SSD P4800X as this support Opal 2.0
What I cannot explain right now is why the drive was working with DAOS in the past.

Recall that we have used this SSD with DAOS in the past. Whatever is preventing this now is a change, perhaps in SPDK but possibly in how DAOS is invoking it.

We probably need to get further information from NSG folks on product specifics regarding Opal support in 905p SSDs. This seems to be a prerequisite for device management through SPDK.

Gert,
We're seeing this when we run identify on our 905p SSDs: " NVMe Controller at 0000:1a:00.0 [8086:2700] [...] Serial Number: PHM29226005S480BGN [...] Admin Command Set Attributes ============================ Security Send/Receive: Supported "
However, when I run nvme_manage, I get an error stating that Opal is not supported (the same error DAOS is spitting out, incidentally):
"Please Input PCI Address(domain:bus:dev.func): 0000:1a:00.00 Opal General Usage:
[1: scan device] [2: init - take ownership and activate locking] [3: revert tper] [4: setup locking range] [5: list locking ranges] [6: enable user] [7: set new password] [8: add user to locking range] [9: lock/unlock range] [10: erase locking range] [0: quit] 1 [2020-06-24 14:37:34.452086] nvme_opal.c: 828:opal_discovery0_end: *ERROR*: Opal Not Supported. "
Any thoughts?

Hi Tom, Colin,
I also compiled the latest master as of yesterday, but it did not make a difference.
