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.
Workaround: Comment out the RANDFILE parameters inside /etc/openwsman/ssleay.cnf and /etc/openwsman/
owsmangencert.sh.
Solution: The issue is resolved in SUSE Linux Enterprise Server 15 Server Pack 2 maintenance update openwsman
version openwsman-2.6.7-3.9.1. For more information, see https://www.suse.com/support/kb/doc/?

RAID level is displayed incorrectly when a virtual disk
created by Dell EMC RAID Controller S150 is degraded
Description: When the virtual disk created using Dell EMC RAID Controller S150 is degraded the mdadm
-D /dev/mdN command displays the RAID level incorrectly. RAID 0 is displayed instead of RAID 1.
Applies to:
SUSE Linux Enterprise Server 15 Service Pack 2
Cause: The operating system considers the virtual disk that is created by Dell EMC RAID Controller S150 as a
foreign VD as the name assigned to the VD is of the form VirtualDiskN.
Workaround: Use the keyword ARRAY in /etc/mdadm.conf command to add the virtual disk on the allow-list.
Solution: Issue is resolved in following Program Temporary Fixes (PTF): www.ptf.suse.com/sle-module-

Status of the RAID 0 LV is displayed as Available when
one of the members of the RAID array is surprise
removed
Description:
When Logical Volume Manager (LVM) is used to create a RAID 0 array and a member of the RAID array is
surprise removed, the lvdisplay command shows the LV status as Available.
Applies to:
SUSE Linux Enterprise Server 15 Service Pack 2
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. For more information, see
SUSE Linux Enterprise Server Knowledge Base article 19716
