2 Compatibility Topics: • • Supported host operating systems and hypervisors Supported packages Supported host operating systems and hypervisors For all the supported host operating systems and hypervisors to run SLES 15 GA guests, see https://www.suse.com/ releasenotes/x86_64/SUSE-SLES/15/#fate-324054. Supported packages For more information on all the changes to packages, such as additions, updates, removals, and changes to the package layout of software, see https://www.suse.
3 New and enhanced in this release The SUSE Linux Enterprise Server 15 release includes changes to installation and the module system such as: ● Unified installer ● Installation without network using Packages media ● Migration from openSUSE Leap to SUSE Linux Enterprise Server ● Extended package search ● Software Development Kit ● Repository Mirroring Tool (RMT) replaces Subscription Management Tool (SMT) For more information on what is new and enhanced in this release, see https://www.suse.
4 Fixes Topics: • • • • • • • • • • • • • • • • • • • • • • BIOS update does not complete when an update is performed using the Linux .BIN files The owsmangencert.
The owsmangencert.sh script fails and reports an error Description: The following error is displayed when a self-signed certificate is being created for the OpenWSMAN server using the owsmangencert.sh script: Cannot write random bytes: 139974501831104:error:2407007A:random number generator:RAND_write_file:Not a regular file:crypto/rand/ randfile.c:183:Filename=/dev/random Applies to: SUSE Linux Enterprise Server 15 Service Pack 2 Cause: Using /dev/random is deprecated in OpenSSL 1.1.1.
Solution: Use the command lvs -o +lv_health_status to check the status of the RAID array. The command displays the output Partial when a member of the RAID array is removed.
Workaround Before starting SLES 15 installation, pass the Kernel boot parameter: "LIBSTORAGE_MDPART=1". Solution The issue is resolved in SUSE Linux Enterprise Server 15 SP1 Systems affected N/A Tracking number 100806 Running supportconfig reboots the server with AMD processor Description When you run supportconfig on Dell EMC PowerEdge servers with LRDDR4 DIMMs, the system reboots the server. Applies to SUSE Linux Enterprise Server 15 Solution Update the Kernel to kernel-default-4.12.14-25.16.
Unable to create or modify namespace for NVDIMM Description When you create or modify a namespace for NVDIMM, it fails. Applies to SUSE Linux Enterprise Server 15 Workaround Use the "--no-autorelabel" option while creating or modifying the namespace. For example: ● Creating namespace—#ndctl create-namespace -r region0 -m raw -f --noautolabel ● Modifying namespace—#ndctl create-namespace --mode raw -e namespace0.
Tracking number 141837 Servers with the AMD Rome processor are unable to read the boost states using cpupower Description Servers with the AMD Rome processor are unable to read the boost states using the cpupower tool. The cpupower tool is unable to read the mperf/aperf registers in the AMD Rome processor, and thus unable to collect the information about boost states. It reports the number of boost states as zero.
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.
Systems affected: PowerEdge R6515, PowerEdge R6525, PowerEdge R7515, PowerEdge C6525, and PowerEdge R7525 Tracking number: 146136, 146448, 146451, 152855 System crashes when rebooted with SR-IOV-enabled QLogic cards Description When the system is rebooted with SR-IOV-enabled QLogic cards, the system crashes and generates a coredump (vmcore) in /var/crash. Applies to SUSE Linux Enterprise Server 15 SP1 Cause: The system crash is due to an issue in the qede driver.
● PSP Initialization failed The PSP message indicates its dependency on the SEV feature. The CCP message indicates that the CCP device is not available. Applies to: SUSE Linux Enterprise Server 15 SP1. Solution: This issue is resolved in SUSE Linux Enterprise Server 15 SP2.
5 Known issues Topics: • • • /proc/mdstat and mdadm -D commands display incorrect statuses when two NVMe devices are surprise removed from a RAID 5 MD array MD RAID layer is not notified of the surprise removal of Samsung NVMe devices Unable to shut down SLES when the graceful shutdown option from iDRAC is selected or when power button is pressed on the server /proc/mdstat and mdadm -D commands display incorrect statuses when two NVMe devices are surprise removed from a RAID 5 MD array Description: When
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.
