Topics: • System configuration requirements • Memory System configuration requirements For detailed system configuration requirements of this version of SUSE Linux Enterprise Server, see the documentation at suse.com/ documentation. Memory The following table lists the system memory requirements for the x86_64 architecture of SUSE Linux Enterprise Server 12. Table 1.
2 Issues and Resolutions SUSE Linux Enterprise Server 12 SP3 does not respond under web stress Description: On Dell EMC 14th generation of PowerEdge servers with AMD EPYC processors, SLES12 SP3 does not respond under web stress. OS logs indicate kernel crash with many page_faults and cpu-recovery failures. Applies to: SUSE Linux Enterprise Server 12 SP3 on R7425, R7415, and R6415 Solution: Update the kernel to version 4.4.103-6.33.1.x86_64.rpm or later.
Cause: The qedf driver which is responsible for FCoE Offloading on Qlogic FastLinQ cards fails to start fcoe function because more command queues are requested than actually available. Solution: You must first boot into the kISO (kernel ISO) image to start installation and when prompted, insert the SUSE Linux Enterprise Server 12 Service Pack 3 DVD to continue the installation. You can find the kISO Image at https://drivers.suse.com/suse/installer-update/sle-12-sp3-x86_64/3.0/installreadme.html.
Cause: These messages indicate the non-existence of a feature and are not errors. The SFN8522 card does not include a PIO buffer support nor a PTP support in the firmware.
System monitor displays less processor cores when Hyperthreading is enabled Description: After booting to SUSE Linux Enterprise Server 12 Service Pack 2 (SLES 12 SP2), the system monitor displays less number of processors than what is listed in /cat/proc/cpuinfo Cause: Libgtop which is part of system monitor has a code that counts the number of processors by copying the content of /proc/cpuinfo into a 64 k buffer and then reads through it, which is inadequate for some hardware (platform with higher numbe
Cause: Not available Workaround: Use Dynamic Host Configuration Protocol (DHCP) address to the initiator. Network ports are displayed as unknown in YaST2 network configuration Description: While configuring a bonding interface, the configured bond-slaves are listed as Unknown Network Device Cause: YaST installer is unable to write the device name in to the ifcfg files. Workaround: Delete the existing configuration of previously configured network interfaces.
Installing SUSE Linux Enterprise Server 12 by using the iDRAC Virtual Media does not resume if the iDRAC network is set to the shared LOM mode Description: When installing SUSE Linux Enterprise Server 12 by using the iDRAC Virtual Media, where the iDRAC network is set to Shared LOM mode, SUSE Linux Enterprise Server 12 installer initiates a reset on the LAN on Motherboard (LOM) devices. Cause: If Spanning Tree is enabled on the switch, there could be a delay in the switch port forwarding network traffic.
Unable to assign link local address via DHCP Description: Unable to assign link local address (169.254.0.1/16) via “BOOTPROTO=autoip”. Cause: Unable to recognize the link local address by DHCP client(dhclient). Workaround: Assign link local address via static using the command “ifconfig ”. Unable to move soft link .desktop file Description: Unable to move soft link .desktop file with type=link. Cause: Unable to deference the source of softlink.
SUSE Linux Enterprise Server 12 Service Pack 3 system soft lockup during I/O Description: In Dell EMC 14th generation PowerEdge servers with AMD EPYC processors, if all NUMA nodes are not populated with memory, system soft lockup occurs during high intensity I/O operations on drives such as NVMe. Applies to: SUSE Linux Enterprise Server 12 SP3 on R7425, R7415, and R6415 Solution: Update the kernel to version 4.4.82-6.3.1.x86_64 or later.
