After executing "rescan-scsi-bus.sh -a -r" on Ubuntu 22.04 VM installed
with image OS/Linux/Ubuntu/22.04/20220326/jammy-live-server-amd64.iso in
ESXi, all non loop devices were removed, and system crashed.
sg3-utils version is 1.46-1.

Steps:
1) create VM with LSI Logic Parallel Disk and install guest OS
jammy-desktop-amd64.iso daily build 26/Mar/2022 in ESXi
2) finish installation and reboot VM
3) exec command "lsblk" in VM:
root@ubuntu:~# lsblk

loop1 7:1 0 78.1M 1 loop /snap/lxd/22525

sr1 11:1 1 1024M 0 rom
4) execute command "rescan-scsi-bus.sh -a -r" in VM and then "lsblk":
root@ubuntu:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
loop0 7:0 0 43.6M 1 loop /snap/snapd/14978
loop1 7:1 0 78.1M 1 loop /snap/lxd/22525
loop2 7:2 0 61.9M 1 loop /snap/core20/1361
Issue: For step 4, we find the non loop disks are removed including the
boot disk sda.
