187一书中的步骤如下：\r\n1. Stop HACMP on the node owning the shared volume group (sometimes a\r\nstop of the applications using the shared volume group may be sufficient).\r\n2. Make the necessary changes to the shared LVM components.\r\n3. Unmount all the file systems of the shared volume group.\r\n4. Varyoff the shared volume group.\r\n5. Export the old volume group definitions on the next node.\r\n6. Import the volume group from one of its disks on the next node. Make sure\r\nyou use the same VG major number.\r\n7. Change the volume group to not auto-varyon at system boot time.\r\n8. Mount all the file systems of the shared volume group.\r\n9. Test the file systems.\r\n10.Unmount the file systems of the shared volume group.\r\n11.Varyoff the shared volume group.\r\n12.Repeat steps 6 through 11 for all the other nodes with an old ODM of the\r\nshared volume group.\r\n13.Start HACMP again on the node usually owning the shared volume group.\r\n\r\n现有IBM双机和共享磁盘柜、oracle使用datavg上，需要在datavg中增加新的lv作为裸设备给oracle使用。如果按照以上步骤操作，vg信息是可以同步，但是原有oracle的裸设备属性全部会被根改。\r\n\r\n大家觉得 5 是否需要呢？

5如果需要，那也太麻烦了吧？
