Grid Infrastructure Install not seeing disks.

3052700Nov 18 2015 — edited Dec 1 2015

Hi,

I posted this in the RAC forum but wanted to see if anyone here could shed some light on this as well.

I am installing a 2 node RAC using Virtual Box 5.0.8 and going through the Grid install (Oracle Grid Infrastructure 11g Release 2 (11.2.0.1) 64 bit.

  when I get to the section of discovering disks(ASM) there are no disks showing up. I use the "Change Discovery Path" option and It still will not pick up on my disk. I have also tried re-downloading the software as well as deleting the disk and recreating them just with ASM, NOT deleting the shared disk in VM manager and then recreating this as well.

   So, created the disks by first creating a new disk in virtual media manager, then made it shareable, then used fdisk to partition the new disk, then created the disk using oracleasm created disk disk1 /dev/sdb1. Both RAC nodes see the disk, "DISK1" . I am wondering if I have some type of permission problem, just not sure what. If anyone has any suggestions and if you need to see output on anything else please let me know. Thanks

 

1)    In the Disk Discovery option I have tried:

                 /dev/oracleasm/disks/*

                /dev/oracleasm/disks/*DISK1

               ORCL:*

2) oracle@rac1 grid]$ lsb_release -a
