[Bug 2028180] [NEW] [SRU][Ubuntu 22.04] Duplicate link for NVMe device by-id

[Michael Reed]

Public bug reported:

[Impact]

When working with NVMe/TCP host functionality, connecting to NVMe
subsystem through multiple controllers can lead to an invalid device
link created in /dev/disc/by-id/ being created.

Steps to reproduce:
Step 1: Install Ubuntu 22.04 LTS (ubuntu-22.04.1-live-server-amd64) on system.
Step 2: Install nvme-cli package, currently installed version is nvme version 1.16
Step 3: In the os terminal, type any nvme connect-all to connect to NVMe subsystems and check the duplicate entries in /dev/disk/by-id/.

This may cause users to choose the wrong link and would not be able to
work with it.

[Fix]

[Test Plan]
Connect to NVMe/TCP subsystem using nvme connect-all. This was tested against a few Dell Storage systems.

Steps to Reproduce:
1. Use nvme connect-all to connect to an NVMe/TCP subsystems
2. Check /dev/disc/by-id

[ Where problems could occur ]


[ Other Info ]

Expected Behavior:
No duplicate entries of NVMe subsystems should exist.
