ASMLIB

O ASMLIB é uma biblioteca Oracle desenvolvida para identificar discos / luns ou partições para o ASM. Esta biblioteca facilita a administração dos discos para o Oracle Grid Infrastructure.

Local para Download dos drivers do ASMLIB:

Instação dos Pacotes RPM

** IMPORTANTE **
Devido a utilização do Kernel uek, deve-se apenas instalar o “Library and Tools” pois o driver do ASMLIB já está incluso no kernel.

Configuring the Oracle ASM library driver.
This will configure the on-boot properties of the Oracle ASM library driver. The following questions will
determine whether the driver is loaded on boot and what permissions it will have. The current values will be
shown in brackets ('[]'). Hitting  without typing an answer will keep that current value. Ctrl-C will abort.
