hostname : hp_data1
Machine Model : 9000/800/rp7410
MACHINE_SERIAL :DEH44145P3
VG Name /dev/vgora
VG Write Access read/write
VG Status available, shared, client
PE Size (Mbytes) 4
Free PE 18475
hostname:hp_data2
Machine Mdoel : 9000/800/rp7410
MACHINE_SERIAL : DEH44145P4
--- Volume groups ---
VG Name /dev/vgora
VG Write Access read/write
VG Status available, shared, server
PE Size (Mbytes) 4
Free PE 18475
under volume group /dev/vgora we have to create two raw files
1./dev/vgora/rmosa_raw_ac_i_2_2gb
2. /dev/vgora/rmosa_raw_sa_2_3gb
The main issue regarding this volume group is:
Is it shared?can we directly create the logical volume?have we to shutdown all packages currently running, Service Guard etc...????
Is it a lengthy procedure and highly sensitive???

Re: How to add the raw devices
Well your clue here is:
MACHINE_SERIAL :DEH44145P3
VG Status available, shared, client <<<<
MACHINE_SERIAL : DEH44145P4
VG Status available, shared, server <<<<
So thsi IS a shared VG, using SLVM.
To make any changes on this VG you will have to shutdown at least one of the packages, possibly both, depending on whether you have the correct OS and/or patches for SNOR (Single Node Online Reconfiguration).
Take as read of this document:

hi galal;
1. stop oracle on both side.
2. "crsctl stop crs" on both side. to stop oracle clusterware.
3. vgchange -a n vgora on second node.
4. vgchange -a n vgora on first node.
5. vgchange -a e vgora on first node.
6. lvcreate -n mosa_raw_ac_i_2_2gb -L 2048 vgora
7. lvcreate -n mosa_raw_sa_2_3gb -L 3072 vgora
8. vgexport -p -v -s -m /tmp/vgora.map vgora
9. rcp /tmp/vgora.map hp_data2:/tmp/
10. in socond node.
11. ll /dev/vgora/group ( note group minor number . let say 0x0?0000)
12. vgexport vgora
13. mkdir /dev/vgora
14. mknod /dev/vgora/group c 64 0x0?000 ( previously noted minor number )
15. vgimport -v -s -m /tmp/vgora.map vgora
16. vgchange -a n vgora ( on both node )
17. vgchange -a s vgora ( on both node )
18. crsctl start crs
19. start oracle
check please for writing mistakes.
and please assign points.
