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工具将适用于ONTAP 的主机操作系统调解器升级到更高的主要版本(例如、从7.x升级到8.x)时、 您必须卸载ONTAP 调解器、因为该工具会尝试检测已向系统注册的存储库中安装的任何RPM的新版本。
由于.rpm文件是作为ONTAP 调解器安装程序的一部分安装的、因此会包含在该搜索中。但是、由于.rpm文件是作为安装程序的一部分解压缩的、并且未从注册的存储库下载、因此无法找到升级。在这种情况下、leapp-upgrade工具将卸载该软件包。
为了保留用于鉴别支持案例的日志文件、您应在操作系统升级之前备份这些文件、并在重新安装ONTAP 调解器软件包之后还原这些文件。由于正在重新安装ONTAP 调解器、因此、在新安装后、需要重新连接与其连接的所有ONTAP 集群。
|
应按顺序执行以下步骤。 重新安装ONTAP 调解器后、您应立即停止ONTAP调解器服务、替换日志文件并重新启动该服务。这将确保日志不会丢失。 |
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 调解器。
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-1.9.0/ontap-mediator-1.9.0 ONTAP Mediator: Self Extracting Installer ..<snip installation>.. [rootmediator-host ~]#
-
停止ONTAP调解器服务。
[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调解器服务。
[rootmediator-host ~]# systemctl start ontap_mediator [rootmediator-host ~]#
-
将所有ONTAP 集群重新连接到升级后的ONTAP 调解器
