Add a disk to an Oracle ASM Disk

1. Link storage to ensure that the operating system can discover devices 1

2. Change the properties of the storage device file

Chown grid: oinstall/dev/mxxxxx

3. Ensure that the disk discovery path of the ASM instance includes the newly added storage device.

4. Create a disk group

Create diskgroup data NORMAL REDUNDANCY

FAILGROUP controller1 DISK

'/Devices/diska1 ',

'/Devices/diska2 ',

'/Devices/diska3 ',

'/Devices/diska4'

FAILGROUP controller2 DISK

'/Devices/diskb1 ',

'/Devices/diskb2 ',

'/Devices/diskb3 ',

'/Devices/diskb4'

ATTRIBUTE 'compatible. asm '= '11. 2', 'compatible. rdbms' = '11. 2 ',

'Sector _ size' = '000000 ';

Description: You can specify a disk that has been used by asmlib lable. ORCL: DISKB1

5. Add a disk

Alter diskgroup data1 ADD DISK

'/Devices/disk * 4' rebalance power 10;

Note:
