Storage Foundation for Oracle® RAC 7.4.1 Configuration and Upgrade Guide - Solaris

To create storage for OCR and voting disk using the SF Oracle RAC installer

1. From the SF Oracle RAC installer menu, enter 2 to select the option Create Storage for OCR and Voting disk.

   The following menu displays:

   1)  Create Oracle Users and Groups
   2)  Create Storage for OCR and Voting disk
   3)  Oracle Network Configuration
   4)  Exit SF Oracle RAC Configuration
   b)  Back to previous menu
   Choose option: [1-4,b,q] (1) 2

2. Enter y to create the storage.

   Do you want the installer to assist you in creating disk groups, 
   volumes and file systems for Oracle? [y,n,q] (n) y

   If you want to create the storage manually, enter n. The installer displays instructions for creating the storage manually. You may skip the remaining steps.

3. Select an appropriate option for the disk group.

   1)  Create a disk group (Shared Storage)
   2)  Use an existing disk group (Shared Storage)
   3)  Create a disk group (FSS)
   4)  Use an existing disk group (FSS)
   b)  Back to previous menu
   Choose option: [1-4,b,q]

   If you want to mirror the CVM volumes, click Yes at the following prompt:

   Do you want to enable mirroring? [y,n,q] (y) y
   

   Create a disk group (Shared Storage)	The installer displays the list of existing shared disks that do not belong to any disk group. Specify the disk (by entering the serial numbers displayed next to the disk name) that you want to use to create the disk group. If you chose to mirror the CVM volumes, select at least two disks. Enter the name of the disk group. Enter the disk group name: [b] (ocrvotedg)
   Use an existing disk group (Shared Storage)	If you choose to use an existing disk group, the installer displays the list of existing non-FSS disk groups. Select a disk group. If you chose to mirror the CVM volumes, select an existing disk group that contains at least two disks for mirroring.
   Create a disk group (FSS)	The installer displays the list of existing local disks that do not belong to any disk group. Specify the disk (by entering the serial numbers displayed next to the disk name) that you want to use to create the disk group. Mirroring is enabled by default. Select at least two disks from different nodes. If you select only one disk or or if you select all disks from one node, the installer will prompt to choose disks again The following disks are not part of any disk group 1) emc_clariion0_103 auto:cdsdisk - - online sys1 2) emc_clariion0_79 auto:cdsdisk - - online exported sys2 b) Back to previous menu If no eligible disks are found, the installer displays the message: No eligible disk found Enter the name of the disk group. Enter the disk group name: [b] (ocrvotedg)
   Use an existing disk group (FSS)	If you choose to use an existing disk group, the installer displays the list of usable FSS disk groups. Disk groups that contain disks from only one node are not listed. To view the list of disks that are contained in the disk group, run the following command: # vxdisk -g disk_group list

4. Review and confirm the configuration information displayed:

   CVM Master node: sys1
   Selected disks (including mirroring):
   			1. Disk_2
   			2. Disk_3
   Disk group name: ocrvotedg
   Is this information correct? [y,n,q] (y)

   The installer initializes the disk groups.

5. Specify whether you want to create separate file systems for OCR and voting disk:

   Do you want to create separate filesystems for ocr and vote? 
   [y,n,q] (y)

6. Enter the name and size of the volume on which you want to store OCR and voting disk information for Oracle 11gR2 and 12cR1.

   • If you have chosen to create a shared file system for OCR and voting disk, enter the following information:

     Enter the volume name for OCR and Voting disk: 
     [b] (ocrvotevol)
     Enter the volume size for OCR and Voting disk in MB 
     (Refer to Oracle documentation to set it properly): [b] (920)

   • If you have chosen to create separate file systems for OCR and voting disk, enter the following information:

     Enter the volume name for OCR: [b] (ocrvol)
     Enter the volume size for OCR in MB 
     (Refer to Oracle documentation to set it properly): [b] (600)
     Enter the volume name for Vote: [b] (votevol)
     Enter the volume size for Vote: [b] (320)

   Note:

   For Oracle 12cR2 or later, create Oracle ASM disk group on the raw CVM volumes where you plan to store OCR and voting files.

7. Enter the Oracle UNIX user name.

   Enter Oracle UNIX user name:  [b] 

8. Enter the Oracle UNIX group name.

   Enter Oracle UNIX group name: [b] (oinstall)

9. Press Return to continue.
10. Review and confirm the configuration information. The installer creates and starts the volumes on all nodes in the cluster.

11. Enter the CFS mount point for OCR and voting disk information, for Oracle 11gR2 and 12cR1.

    • If you have chosen to create a shared file system for OCR and voting disk, enter the following information:

      Enter the mount point location for CFS 
      (common for all the nodes) [b] (/ocrvote)

    • If you have chosen to create separate file systems for OCR and voting disk, enter the following information:

      Enter the mount point location for OCR storage 
      (common for all the nodes): [b] (/ocr)
      Enter the mount point location for Vote storage 
      (common for all the nodes): [b] (/vote)

    The installer creates the CFS mount points and sets the ownership. Press Return to continue.
12. Verify that the corresponding CVMVolDg and CFSMount resources are online on all nodes in the cluster:

    Note:

    It takes a few minutes for the CVMVolDg resource to come online.
