Cannot locate multipathing nvme block device by ledctl in RHEL 9.2

[jackeichen]

When enable multipathing nvme device and Intel VROC technology, the bellow command will failed:

# ledctl locate=/dev/nvme1n1
ledctl: /dev/nvme1n1: device not supported
ledctl: IBPI LOCATE: missing block device(s)... pattern ignored.

# ledctl locate=/dev/nvme1c1n1
ledctl: IBPI LOCATE: missing block device(s)... pattern ignored.

The tool version is 0.97, here is my configuration:

# ledctl -L

Hey @jackeichen, Support of nvme multipath devices has been introduced recently: https://github.com/intel/ledmon/commit/82c3675cadd1c95058b115c5301683f41372fc72

Please test with latest upstream ledmon to see if it is working now.

It works in my configuration.

Thanks for the reply.
