PowerEdge servers with the AMD Rome processor fail
to detect an NVMe drive after multiple hot plugs
Description: The PowerEdge servers with the AMD Rome processor fail to detect an NVMe drive after multiple hot
plugs.
Applies to:
SUSE Linux Enterprise Server 15 SP1
Cause: Issue in pciehp driver.
Workaround:
NOTE: The output of each command varies based on your system configuration.
Follow the steps:
1. Identify the parent device to which the NVMe device is connected using the following command:
lspci -t
-+-[0000:e0]-+-00.0
| +-00.2
| +-01.0
| +-02.0
| +-03.0
| +-03.1-[e2]----00.0
From the above snippet, the device e2:00.0 is the NVMe device and the device e0:03.1 is the
parent device. The parent device is used for the steps that are described subsequently.
2. Read the Slot Status Register in the PCI Express Capability structure by running the following
command:
setpci -s e0:03.1 CAP_EXP+0x1a.w
Output: 0148 (value returned)
3. Clear the event bits that are impacted by running the following command:
setpci -s e0:03.1 CAP_EXP+0x1a.w=0x0108
4. Re-read the Slot Status Register to confirm that event bits are cleared by running the following
command:
setpci -s e0:03.1 CAP_EXP+0x1a.w
Output: 0040 (value returned)
5. Unplug the drive and then plug-in the drive after clearing the event bits.
Solution:
The issue is resolved in SUSE Linux Enterprise Server 15 SP2.
