3. Tao diskgroup
VNC
# . grid
# env
|grep ORA
# asmca
Hoặc dùng câu lệnh:
CREATE DISKGROUP CRS2 NORMAL REDUNDANCY disk
'/dev/rdsk/c15t60060E80212E360050602E36000000A4d0s6' name CRS1,
'/dev/rdsk/c15t60060E80212E360050602E36000000A5d0s6' name CRS2,
'/dev/rdsk/c15t60060E80212E360050602E36000000A6d0s6' name CRS3
ATTRIBUTE 'compatible.asm' = '11.2';
Note:
- Nếu quên 'compatible.asm' = '11.2' thì nó sẽ mặc định là 10.2 --> Phải tạo lại.
- Nếu tạo diskgroup như này thì bị lỗi chuyển votedisk (chuyển OCR OK):
CREATE DISKGROUP CRS NORMAL REDUNDANCY
FAILGROUP failgrp1 DISK
'/dev/rdsk/c15t60060E80212E360050602E36000000A4d0s6' name CRS1,

FAILGROUP failgrp2 DISK
'/dev/rdsk/c15t60060E80212E360050602E36000000A6d0s6' name CRS3
ATTRIBUTE 'compatible.asm' = '11.2';
