Next, find the PCI information of the target SSD.
The example below is for /dev/nvme17n1
# ls -l /sys/block/nvme17n1
lrwxrwxrwx 1 root root 0 Jul 16 14:02 /sys/block/nvme17n1
-> ../devices/pci0000:2d/0000:2d:00.0/0000:2e:00.0/0000:
2f:04.0/0000:30:00.0/0000:31:01.0/0000:44:00.0/0000:45:01.0/0000:
47:00.0
/nvme/nvme17/
nvme17n1
/dev/nvme17n1 Bus:Device.Function
More information of /dev/nvme17n1 could be probed for cross-reference if needed
# udevadm info -n /dev/nvme17n1 -a
…
looking at parent device '/devices/pci0000:2d/0000:2d:00.0/0000:2e:00.0/0000:

Now, find the slot information of the target SSD using the target SSD PCI information
(Bus:Device:Function).
# lspci -vvvs 47:00.0
47:00.0 Non-Volatile memory controller: Intel Corporation Device 0a54 (prog-if 02 [NVM
Express])
Subsystem: Intel Corporation Device 4702
Physical Slot: 17-1
/dev/nvme17n1 slot info
Control: I/O- Mem+ Bu SpecCycle- MemWINV- VGASnoop- Stepping-
SERR+ FastB2B-
Please note, the exact slot value of any target SSD depends on the actual enumeration of
the kernel, which may or may not be consistent with its physical slot number in the JBOF. In
this case, here is the information shown in JBOF BMC (under Server Health/Pooled NVMe
Storage).
