若要將主機作業系統 for ONTAP Mediator 升級至更新版本、您必須先解除安裝 ONTAP Mediator 。
關於這項工作
當您使用 leapp-upgrade 工具將主機作業系統 for ONTAP Mediator 升級至較新的主要版本（例如從 7.x 升級至 8.x ）時、 您必須解除安裝 ONTAP Mediator 、因為此工具會嘗試偵測安裝在系統儲存庫中的任何 RPM 的新版本。
由於 .rpm 檔案是 ONTAP Mediator 安裝程式的一部分、因此會包含在該搜尋中。不過、由於 .rpm 檔案已在安裝程式中解壓縮、且未從已註冊的儲存庫下載、因此無法找到升級。在這種情況下、 leapp-upgrade 工具會解除安裝套件。
為了保留用於分類支援案例的日誌文件，您應該在升級作業系統之前備份這些文件，並在重新安裝 ONTAP Mediator 軟體包後恢復它們。安裝 ONTAPMediator 後，需要重新連線連接到該軟體包的 ONTAP 叢集。
|
應依序執行下列步驟。重新安裝 ONTAP Mediator 後，應立即停止 ontap_mediator，替換日誌文件，然後重新啟動它。這樣做是為了確保日誌不會遺失。 |
步驟
-
備份記錄檔。
[rootmediator-host ~]# tar -czf ontap_mediator_file_backup.tgz -C /opt/netapp/lib/ontap_mediator ./log ./ontap_mediator/server_config/ontap_mediator.user_config.yaml [rootmediator-host ~]# tar -tf ontap_mediator_file_backup.tgz ./log/ ./log/ontap_mediator.log ./log/scstadmin.log ./log/ontap_mediator_stdout.log ./log/ontap_mediator_requests.log ./log/install_20230419134611.log ./log/scst.log ./log/ontap_mediator_syslog.log ./ontap_mediator/server_config/ontap_mediator.user_config.yaml [rootmediator-host ~]#
-
使用 leapp-upgrade 工具執行升級。
[rootmediator-host ~]# leapp preupgrade --target 8.4 ..<snip upgrade checks>.. ..<fix issues found>.. [rootmediator-host ~]# leapp upgrade --target 8.4 ..<snip upgrade>.. [rootmediator-host ~]# cat /etc/os-release | head -2 NAME="Red Hat Enterprise Linux" VERSION="8.4 (Ootpa)" [rootmediator-host ~]#
-
重新安裝 ONTAP Mediator 。
重新安裝 ONTAP Mediator 之後、請立即執行其餘步驟、以避免記錄檔遺失。 [rootmediator-host ~]# ontap-mediator-1.10/ontap-mediator-1.10 ONTAP Mediator: Self Extracting Installer ..<snip installation>.. [rootmediator-host ~]#
-
停止 ontap_mediator。
[rootmediator-host ~]# systemctl stop ontap_mediator [rootmediator-host ~]#
-
取代記錄檔。
[rootmediator-host ~]# tar -xf ontap_mediator_log_backup.tgz -C /opt/netapp/lib/ontap_mediator [rootmediator-host ~]#
-
啟動 ontap_mediator。
[rootmediator-host ~]# systemctl start ontap_mediator [rootmediator-host ~]#
-
將所有 ONTAP 叢集重新連線至升級的 ONTAP Mediator
