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 <ENTER> without typing an

answer will keep that current value.  Ctrl-C will abort.

 

Default user to own the driver interface [oracle]: oracle

Default group to own the driver interface [oinstall]: oinstall

Start Oracle ASM library driver on boot (y/n) [y]: y

Scan for Oracle ASM disks on boot (y/n) [y]: y
