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
Default group to own the driver interface []: dba
Start Oracle ASM library driver
on
boot (y/n) [n]: y
Scan
for
Oracle ASM disks
on
boot (y/n) [y]:
Writing Oracle ASM library driver configuration: done
Initializing the Oracle ASMLib driver: [ OK ]
Scanning the system
for
Oracle ASMLib disks: [ OK ]
