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
使用 leapp-upgrade 工具升級ONTAP Mediator 的主機作業系統前，請先解除安裝ONTAP Mediator。此工具會檢查已註冊倉庫中是否有新的 RPM 版本。
ONTAP Mediator 安裝程式會安裝一個 .rpm 文件，leapp-upgrade 工具會將其包含在搜尋範圍內。由於安裝程式會解壓縮文件而不是從註冊的儲存庫下載文件，因此該工具找不到升級程式。您必須使用 leapp-upgrade 工具卸載該軟體包。
步驟
-
備份日誌檔：
[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-1.11.0/ontap-mediator-1.11.0 ONTAP Mediator: Self Extracting Installer ..<snip installation>.. [rootmediator-host ~]#
-
停止 ontap_mediator：
[rootmediator-host ~]# systemctl stop ontap_mediator [rootmediator-host ~]#
-
替換日誌檔：
[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叢集重新連接到升級後的ONTAP中介器：
