Conhecendo um pouco do OAKCLI - (Oracle Appliance Kit Command Line Interface)

O OAKCLI (Oracle Appliance Kit Command Line Interface) é uma interface de linha de comando para gerenciamento do Oracle Database Appliance (ODA) utilizada para execução de tarefas como, aplicação de patches, gerenciamento de maquinas virtuais, criação de databases, configuração de core keys, diagnostico de hardware, etc.
O "executável" fica localizado no diretório /opt/oracle/oak/bin/oakcli, sendo que o usuário root deve ter a variável de ambiente ORA_OAK_HOME definida com este diretório base (/opt/oracle/oak). Vale destacar que para ter permissão para executar todas as funcionalidades, é preciso que a execução seja realizada com o usuário root. 
Dependendo da versão do Oracle Appliance Manager e do Hardware utilizado, alguns comandos do oakcli podem não estar disponíveis ou mesmo, podem apresentar mais opções. Para verificar as opções disponíveis para execução do oakcli podemos executar um oakcli -h e ou oakcli show -h.
[root@ODA_TST01 ~]# oakcli -h
Usage:  oakcli show       - show disk, diskgroup, expander, controller, storage, version, fs, raidsyncstatus, dbhomes, dbstorage, databases, db_config_params, core_config_key, env_hw, asr
        oakcli configure  - configures the network or asr or additionalnet
        oakcli apply      - applies the core_config_key
        oakcli locate     - locates a disk
        oakcli deploy     - deploys the Database Appliance
        oakcli update     - updates the Database Appliance
        oakcli validate   - validates the Database Appliance
        oakcli manage     - manages the oak repository, diagcollect e.t.c
        oakcli unpack     - unpack the given package to oak repository
        oakcli copy       - copies the deployment config file
        oakcli upgrade    - upgrades database
        oakcli stordiag   - run storage diagnostic tool on both node
        oakcli test       - test asr
        oakcli orachk     - performs configuration settings check on ODA
        oakcli create     - creates database, dbstorage, snapshotdb, dbhome, db_config_params file
        oakcli delete     - deletes database, dbstorage, dbhome, db_config_params file

For detailed help on each command and object and its options use:
oakcli <command> <object> -h
Vale lembrar que, sempre que existir uma duvida quando a sintaxe utiliza, podemos e devems utilizar o comando help, que nos mostrara as "opções" disponíveis para cada comando. Por exemplo, precisamos realizar o diagnostico de um disco especifico e não lembramos a sintaxe do comando. Abaixo não será mostrado todo o resultado do comando devido ao seu temanho.
[root@ODA_TST01  ~]# oakcli stordiag -h
Usage:
      oakcli stordiag -h | n

Podemos também ativar ou desativar o LED de identificação de um disco (LED amarelo). Este comando pode ser bastante util quando existir a necessidade de substituição de um disco com problemas, caso o mesmo não tenha sido identificado automaticamente.
[root@ODA_TST01 ~]# oakcli locate pd_01
Usage:
oakcli locate disk  <diskname>   <on | off>
where:
        on     - turns on the  LED of the given disk
        off    - turns off the LED of the given disk

Outro comando bastante usado é o validate, que pode ser consultado utilizando o -h, conforme usamos no comando show.
[root@ODA_TST01 ~]# oakcli validate -h
Usage:
 oakcli  validate [-V | -l | -h]
 oakcli  validate [-v] [-f absolute output_file_name] [-a | -d | -c check1[,check2] [-ver <patch version>]]
        ARGUMENTS:
                -v      verbose output
                -f      output_file_name.The output is sent to the file instead of standard output
                -a      run all checks
