You approach seems incorect.
The devices are shared right ? So why do you re-create partitions on
the server B, after you have created them and prepared your devices on
Server A ?
The procedure should be:
Server A
fdisk /dev/sde
-> create partition
fdisk /dev/sdd
-> create partition
/etc/init.d/oracleasm createdisk ... /dev/sde1
/etc/init.d/oracleasm createdisk ... /dev/sdf1
Server B
fdisk /dev/sde
"p" for print, you should see the partition created
"w" to rewrite it, and refresh in memory partition table
fdisk /dev/sdf
"p" for print, you should see the partition created
"w" to rewrite it, and refresh in memory partition table
/etc/init.d/oracleasm scandisks
/etc/init.d/oracleasm listdisks
-> should show your marked devices
Use dbca to create diskgroups.

Hello,
Here is what I am trying to do.
two servers: Let's call A and B in short
ASMLib 1.0 installed and configured on server A and B
two shared raw devices /dev/sde and /dev/sdf
Server A
create 1 partition on each of them, /dev/sde1 and /dev/sdf1, using fdisk
command
/etc/init.d/oracleasm createdisk VOL1 /dev/sde1
/etc/init.d/oracleasm createdisk VOL2 /dev/sdf1
/etc/init.d/oracleasm listdisks (shows VOL1 and VOL2)
run dbca to configure ASM: DATA_1 --> VOL1 and DATA_2 --> VOL2
Server B
use sfidk -R to create 1 partition on /dev/sde and /devsdf
/etc/init.d/oracleasm scandisks <---- want to give server B a notice of
VOL1 and VOL2 ASM diskgroups
/etc/init.d/oracleasm listdisks <----- show nothing ????
run dbca to configure ASM: <--- can't see any asn disk group(s)
Does anyone can point it out to the missing/wrong procedure of the above
configuration?
If I use /etc/init.d/oracleasm createdisk VOL1 /dev/sde1 on Server B, I can
see the diskgroup while configuring ASM, but I got,
ora-15003, Disk Group DATA_1 already mounted in another lock name space
*****************************
Does anyone have any idea of how to make that working? Many thanks for all
the help.
