Namespaces on MZQL2960HCJR-00A07

[Michael Fuckner]

I have a system with 2x PM9A3 (FW GDC5302Q) and nvme1 shall use namespacesfor testing.

I could use nvme detach-ns, delete-ns and create-ns, but it fails at attach-ns the new namespace to make it usable:

test135:~ # nvme id-ctrl /dev/nvme1|grep -e nn -e cntlid
cntlid    : 0x6
nn        : 32
test135:~ # nvme attach-ns /dev/nvme1 --namespace-id=1 -controllers=0x6
NVMe status: Controller List Invalid: The controller list provided contains invalid controller ids(0x211c)

Any idea how to attach this or other namespaces back so I can use the drive?

Regards,
 Michael!

The long options should use "--" rather than just the single "-". I'm
unsure if that changes the parsing, though.

Was the namespace attached to cntlid 0x6 prior to the detach/delete part
of the test?

When you created the namespace, did the output confirm the namespace was
created as nsid 1?

Is the namespace attached to any other controllers? You have to specify
multi-controller enabled when creating the namespace in that case.

doesn't make a difference:
nvme attach-ns /dev/nvme7 -c 6 -n 1
NVMe status: Controller List Invalid: The controller list provided 
contains invalid controller ids(0x211c)

this is a similar system also all drives connected directly to EPYC 
CPUs. This drive still has the default ns:

yes, I can create and delete namespaces, but I can not attach them:

test220:~ # nvme create-ns /dev/nvme7 -s 26214387 -c 26214387 -b 4096
create-ns: Success, created nsid:1
test220:~ # nvme attach-ns /dev/nvme7 -n 1 -c 0x6
NVMe status: Controller List Invalid: The controller list provided 
contains invalid controller ids(0x211c)
test220:~ # nvme delete-ns /dev/nvme7 -n 1
delete-ns: Success, deleted nsid:1
test220:~ #

no, just 4 lanes from CPU to NVMe Drive.

Hope this helps,
  Michael!

Hi,

got another drive to play with (Micron 7400) and I can use the nvme tool as expected- so I just consider Samsung Firmware broken?
