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.
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-
