Hi bpolarsk:
I have not yet been able to install 11g, so i dont know if its actually going to work. But here is what i have done

I am trying to use RAW volumes created from LVM for the OCR and Voting disk and couple of physical disks (block devices) for the ASM data disks.

Data Disk on HN
===============
/dev/ida/c0d1

Flash Disk on HN
================
/dev/ida/c0d2

OCR and Voting Disk Logical Volumes on HN
=========================================
/dev/oravg/ocr
/dev/oravg/vote


Check their major and minor numbers

ls -l /dev/oravg/ocr /dev/oravg/vote /dev/ida/c0d1 /dev/ida/c0d2


ls -l /dev/oravg/ocr /dev/oravg/vote /dev/ida/c0d1 /dev/ida/c0d2
brw-r----- 1 root disk 72, 16 Nov 5 11:56 /dev/ida/c0d1
brw-r----- 1 root disk 72, 32 Nov 5 11:56 /dev/ida/c0d2
lrwxrwxrwx 1 root root 21 Nov 5 16:45 /dev/oravg/ocr -> /dev/mapper/oravg-ocr
lrwxrwxrwx 1 root root 22 Nov 5 16:46 /dev/oravg/vote -> /dev/mapper/oravg-vote

ls -l /dev/mapper/oravg-ocr
brw-rw---- 1 root disk 253, 9 Nov 5 16:45 /dev/mapper/oravg-ocr

ls -l /dev/mapper/oravg-vote
brw-rw---- 1 root disk 253, 10 Nov 5 16:46 /dev/mapper/oravg-vote

Add these devices to the two containers

vzctl set 3001 --devices b:72:32:rw --devices b:72:16:rw --devices b:253:9:rw --devices b:253:10:rw --save

vzctl exec 3001 mknod /dev/ocr b 253 9
vzctl exec 3001 mknod /dev/vote b 253 10

vzctl exec 3001 mknod /dev/data_dg1_d1 b 72 16
vzctl exec 3001 mknod /dev/flash_dg1_d1 b 72 32

vzctl set 3002 --devices b:72:32:rw --devices b:72:16:rw --devices b:253:9:rw --devices b:253:10:rw --save

vzctl exec 3002 mknod /dev/ocr b 253 9
vzctl exec 3002 mknod /dev/vote b 253 10

vzctl exec 3002 mknod /dev/data_dg1_d1 b 72 16
vzctl exec 3002 mknod /dev/flash_dg1_d1 b 72 32
