PDF
Para actualizar el sistema operativo host de ONTAP Mediator con SCST instalado a una versión posterior, debes desinstalar ONTAP Mediator. Después de la actualización del sistema operativo, puedes reinstalar tu versión actual de ONTAP Mediator o actualizar a una versión más reciente.
-
Esta tarea se aplica a las versiones de ONTAP Mediator con SCST instalado. Si instalaste ONTAP Mediator 1.12 o posterior con soporte solo para HTTPS, el paquete SCST no está instalado y puedes actualizar el sistema operativo host sin afectar a ONTAP Mediator. Consulta la documentación del proveedor del sistema operativo host para ver las instrucciones de actualización del sistema operativo. Después de actualizar el sistema operativo host, si necesitas actualizar tu versión de ONTAP Mediator, consulta "Instale el paquete de instalación del Mediador ONTAP".
-
Antes de actualizar el sistema operativo host para ONTAP Mediator con la herramienta leapp-upgrade, desinstale ONTAP Mediator. La herramienta comprueba si hay nuevas versiones de RPM en los repositorios registrados.
-
El instalador de ONTAP Mediator instala un archivo .rpm, que la herramienta leapp-upgrade incluye en la búsqueda. Debido a que el instalador descomprime el archivo en lugar de descargarlo de un repositorio registrado, la herramienta no puede encontrar una actualización. Debe utilizar la herramienta leapp-upgrade para desinstalar el paquete.
-
Realiza una copia de seguridad de los archivos de registro:
[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 ~]#
-
Realice la actualización con la herramienta leapp-upgrade:
[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 ~]#
-
Reinstale el mediador ONTAP :
Realice el resto de los pasos inmediatamente después de volver a instalar ONTAP Mediator para evitar la pérdida de archivos de registro. [rootmediator-host ~]# ontap-mediator-1.12.0/ontap-mediator-1.12.0 ONTAP Mediator: Self Extracting Installer ..<snip installation>.. [rootmediator-host ~]#
-
Detener ontap_mediator:
[rootmediator-host ~]# systemctl stop ontap_mediator [rootmediator-host ~]#
-
Reemplazar los archivos de registro:
[rootmediator-host ~]# tar -xf ontap_mediator_log_backup.tgz -C /opt/netapp/lib/ontap_mediator [rootmediator-host ~]#
-
Iniciar ontap_mediator:
[rootmediator-host ~]# systemctl start ontap_mediator [rootmediator-host ~]#
-
Vuelva a conectar todos los clústeres ONTAP al mediador ONTAP actualizado:
