Code: [[email protected] 2.6.9-5.0.5]# uname -r 2.6.9-5.0.5.EL So using the root account, I have successfully installed ASMLib without any problems. Once its done you can start the service and ASM instance as well.

  3. They're all logical volumes built on /sda4, an extended partition.
  4. I have formatted the drives with ext3 filesystem --using the mke2fs -j command.
  5. Actually we configured ASM on one host later that host was upgraded to Linux version 5.8 once the O/S upgrade has been done system admin failed to upgrade the ASMLIB rpms,
  6. But /dev/sda11 has already been owned by oracle!
  7. After all nodes have been configured, run "service oracleasm status" on all nodes to verify that the oracleasm service is installed and working properly.

This will configure the on-boot properties of the Oracle ASM library driver. Code: [[email protected] ~]$ ls -al /dev/sda11 brw-rw---- 1 oracle dba 8, 11 Nov 20 09:17 /dev/sda11 [[email protected] ~]$ ls -al /dev/sda12 brw-rw---- 1 oracle dba 8, 12 Nov 20 09:17 /dev/sda12 The system admin then partitions this device using the linux fdisk utility.
