Per aggiornare il sistema operativo host per ONTAP Mediator a una versione successiva, è necessario prima disinstallare ONTAP Mediator.
A proposito di questa attività
Prima di aggiornare il sistema operativo host per ONTAP Mediator con lo strumento leapp-upgrade, disinstallare ONTAP Mediator. Lo strumento verifica la presenza di nuove versioni RPM nei repository registrati.
Il programma di installazione ONTAP Mediator installa un file .rpm, che lo strumento leapp-upgrade include nella ricerca. Poiché il programma di installazione decomprime il file anziché scaricarlo da un repository registrato, lo strumento non riesce a trovare un aggiornamento. Per disinstallare il pacchetto è necessario utilizzare lo strumento leapp-upgrade.
