You cannot use only yum to downgrade (or upgrade) OMSA. You can try, but you will most likely end up with a non-functional OMSA installation.
To change OMSA versions you must first uninstall the current version, then install whatever version you want to install. Below is the script I use to remove OMSA, then upgrade (or downgrade). To downgrade, change the URL to point to the version you want from https://linux.dell.com/repo/hardware/ # uninstall OMSA /opt/dell/srvadmin/sbin/srvadmin-uninstall.sh -f # remove all packages originating from dell-omsa repository yum -y remove $(/usr/sbin/yumdb search from_repo "dell-omsa*" | grep '[a-z]' | grep -vE "(from_repo|Loaded plugins)" ) # remove the repo definition yum -y remove dell-omsa-repository yum-dellsysid # manually remove any files left, just in case... rm -f /etc/yum.repos.d/dell-omsa-repository.repo rm -rf /opt/dell/srvadmin /usr/libexec/dell_dup /usr/share/firmware/dell # /tmp mount be mounted with exec permissions for firmware updates to complete # at least, this was the case for update_firmware -- not sure for dsu if [[ $(grep [[:space:]]\/tmp[[:space:]] /etc/fstab|grep -c noexec) -gt 0 ]]; then RESETNOEXEC=1 mount -o remount,exec /tmp fi # install new repo for Dell System Update/OMSA # Modify this URL to match your desired version wget -q -O - https://linux.dell.com/repo/hardware/DSU_18.05.00/bootstrap.cgi | bash # Install DSU, OMSA, idracadm7 yum -y install srvadmin-all dell-system-update srvadmin-idracadm7 -----Original Message----- From: Linux-PowerEdge [mailto:[email protected]] On Behalf Of Lorenzo Grio Sent: Monday, June 18, 2018 4:26 AM To: [email protected] Subject: [Linux-PowerEdge] How downgrade OMSA by yum (CentOS) Hi, I have installed OMSA 9.1 on CentOS 7.5, but due to problem with CMOS Battery on PE2950 I should downgrade OMSA to 8.5. How can I downgrade it? How can I install an old version of OMSA by yum? Thanks in advance.
