The operating system installer does not display the
MD virtual disks created using Dell EMC Software
RAID Controller under the guided setup
Description If MD virtual disks are created using Dell EMC Software RAID Controller on a hard disk that is not
formatted before installation, the operating system installer may not display the MD virtual disks under
the guided setup. For more information, see https://www.suse.com/support/kb/doc/?id=000019839.
Applies to SUSE Linux Enterprise Server 15 Service Pack 2
Solution Format the hard drive before creating the MD virtual disk or pass the kernel boot parameter
LIBSTORAGE_MDPART=1 to list the MD virtual disk under the guided setup.
Systems affected All Dell EMC PowerEdge servers
Tracking number 189521
MD RAID layer is not notified of the surprise removal
of Samsung NVMe devices
Description: When a virtual disk is created on the MD RAID layer using a Samsung NVMe device, the MD RAID
layer is not notified of the surprise removal of the NVMe drive. The output of the mdadm -D command
displays an incorrect status of the MD RAID virtual disk (VD). The issue is observed on Dell Express Flash
PM1725a, PM1725b, Enterprise NVMe Agnostic (AGN) devices. The array status reporting is incorrect.
When I/O operations are performed, I/O errors are observed as expected and the file-system changes to
read-only.
Applies to:
SUSE Linux Enterprise Server 15 Service Pack 2
Cause: The issue is related to handling devices which showcase multipath capability.
Workaround: Pass the multipath=N parameter to the nvme_core driver module.
Systems
affected:
All Dell EMC PowerEdge systems with support for NVMe surprise removal feature
Tracking number: 175555
Unable to shut down SLES when the graceful
shutdown option from iDRAC is selected or when
power button is pressed on the server
Description
When you select the Graceful Shutdown option from any system management interface such as iDRAC
or press the power button, the system goes to a suspended state and all the tasks stop. Even the
firmware updates from iDRAC interface that requires restart, takes longer time to update, and the system
will be Hard reset upon iDRAC watchdog time expiration.
Applies to SUSE Linux Enterprise Server 15
Workaround Change the power settings.
1. Go to Settings > Power.
2. In the Suspend and power button section, select Power Off from the When the Power Button is
pressed drop-down list.
NOTE: By default the Suspend option is selected.
