Public bug reported:
1. Run IO on mixed volumes and snaps from 3 hosts - RH9 , Suse (SLES 15 sp4)
and Ubuntu (22.04.01)
2. Running scripts of randome port toggeling
after short time (few minutes of running) - got into the following state
on the ubuntu host and IOs stopped arriving to the storage:
root@sio-dcoe-116bs-3:~# nvme list-subsys
nvme-subsys0 - NQN=nqn.1988-11.com.dell:powerflex:00:2b8275a55ee1a80f

root@sio-dcoe-116bs-3:~#
This situation remained, what seems to be forever.
