Good morning every one!
I've configured completely single Oracle database using ASM.
So, the diskgroup was created as
[root@oravn etc]# ls -lrt /dev/raw
total 0
crw------- 1 root root 162, 1 Dec 2 16:27 raw1
crw------- 1 root root 162, 4 Dec 2 16:27 raw4
crw------- 1 root root 162, 3 Dec 2 16:27 raw3
crw------- 1 root root 162, 2 Dec 2 16:27 raw2
crw------- 1 root root 162, 5 Dec 2 16:27 raw5
crw------- 1 root root 162, 6 Dec 2 16:27 raw6
[root@oravn etc]# oracleasm listdisks
DATA1
DATA2
DATA3
DATA4
DATA5
DATA6
It was used to Normal Redundancy ~140gb/2, one raw=24gb (~70gb used truly). And now, I wish to create some raws and configure raw devices such as:
- One new raw as 90gb
- Add to the exists +DATA diskgroup.
May you clarify me something:
1. When I finsh the task:
+ fdisk to create raw
+ locate in /etc/rawdevices, example: /dev/raw/raw7 /dev/cciss/c0d1p15, expand to 6 new raws from 15 to 20.
Then, what will I do next step?
2. If I will not use "$ORACLE_HOME/bin/localconfig add", so what I will do to add the new raw device to exists +DATA diskgroup?
3. If the exits raw device was 24g/raw, can I create a new raw device which as 90gb/raw?
Thank you very much!
