要将适用于ONTAP 调解器的主机操作系统升级到更高版本、必须先卸载ONTAP 调解器。
关于此任务
使用 leapp-upgrade 工具升级ONTAP Mediator 的主机操作系统之前，请先卸载ONTAP Mediator。该工具会检查已注册仓库中是否有新的 RPM 版本。
ONTAP Mediator 安装程序会安装一个 .rpm 文件，leapp-upgrade 工具会将其包含在搜索范围内。由于安装程序会解压缩文件而不是从注册的存储库下载文件，因此该工具找不到升级程序。您必须使用 leapp-upgrade 工具卸载该软件包。
步骤
-
备份日志文件：
[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 工具执行升级：
[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 ~]#
-
重新安装ONTAP Mediator：
重新安装ONTAP 调解器后立即执行其余步骤、以防止日志文件丢失。 [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 ~]#
-
替换日志文件：
[rootmediator-host ~]# tar -xf ontap_mediator_log_backup.tgz -C /opt/netapp/lib/ontap_mediator [rootmediator-host ~]#
-
启动 ontap_mediator：
[rootmediator-host ~]# systemctl start ontap_mediator [rootmediator-host ~]#
-
将所有ONTAP集群重新连接到升级后的ONTAP中介器：
