howto add additional disks to vmbox and asm diskgroups.doc
TRANSCRIPT
CR010_2
2. Modify VM Settings & Add additional virtual hard disks. 2 disks for ASM, 1 for temporary backups. Edit the VM created, for the following:
1. Disabling 'Enable PAE/NX' processors extended feature.
2. For Adding additional virtual Hard disks.
3. For Modifying and Adding additional Virtual Network Adapters for each VM.
Disabling 'Enable PAE/NX' processors extended feature:- Goto VM Setting- Select tab 'Processor' Under System, Uncheck 'Extended features' option.
For Adding additional virtual Hard disks:Procedure:
- Select VM, RightClick and Select 'Settings' Option
- Select edbar2p5 VM -> Settings -> Storage -> Select the Controller:SATA, Click '+' to add Hard Disk Option-> Choose create new -> Choose 'VDI' as hardisk type-> Dynamically allocated ->ExtraVDisk1 and 20.-> Click Similarly, Add 2 more disks for ASM as ASMVDisk1,ASMVDisk2 each of 10GB.
For Modifying and Adding additional Virtual Network Adapters for each VM.:- Select VM, RightClick and Select 'Settings' Option
- Click on Network. Select Host-only Adapter- Click 'OK'.Final Network Adapters..ScreenShot.:
2.Installing ASM Libraries & Creating Disk groups.As root, install the ASM libraries ( copy from the existing oel5.4 media, or else can be downloaded..)
Note: All ASMLib installations require the oracleasmlib and oracleasm-support packages appropriate for their machine. The driver packages are named after the kernel they support. Run the "uname -r" command on your machine to determine your kernel version. The corresponding package has the name oracleasm-. Also, see the release notes
1.
[root@edbar2p5 ~]# uname -r
2.6.18-371.1.2.0.1.el52.
Since Kernel Upgraded, Do not Copy the ASM libraries available in the Installation DVD, Rather Goto below URL and download the appropriate require ASM Library.

-* Ensure the virtual disk added for ASM are visible when FDISK command.

5. Creating ASM Disks
/usr/sbin/asmtool -C -l /dev/oracleasm -n asmdisk1 -s /dev/sdc -a force=yes
/usr/sbin/asmtool -C -l /dev/oracleasm -n asmdisk2 -s /dev/sdd -a force=yes
#oracleasm listdisks
ASMDISK1
ASMDISK2#chown oracle:oinstall /dev/sdc
#chownn oracle:oinstall /dev/sdd
#chmod 600 /dev/sdc#chmod 600 /dev/sdd
