1. Lun is mounted on the storage

two。 Do the following on the operating system (there is no need to restart the operating system):

Echo "- -" > / sys/class/scsi_host/host0/scan

Echo "- > / sys/class/scsi_host/host1/scan

.

Complete the operation in one step:

Echo "- > / sys/class/scsi_host/host**/scan

3. Edit / etc/multipath.conf

Add:

Multipath {

Wwid 360002ac000000000000000dd00012d32

Alias mpath2

}

Multipath {

Wwid 360002ac0000000000000004000012d47

Alias mpath3

}

Restart the multipath service or reload

4. Format the disk:

Fdisk / dev/mapper/mpath2

Fdisk / dev/mapper/mpath2

Partprobe / dev/mapper/mpath2

Partprobe / dev/mapper/mpath3

5.asmlib binding, or some other way:

/ etc/init.d/oracleasm createdisk ASMDISK1 / dev/mapper/mpath2p1

Marking disk "ASMDISK1" as an ASM disk: [OK]

/ etc/init.d/oracleasm createdisk ASMDISK2 / dev/mapper/mpath3p1

Marking disk "ASMDISK2" as an ASM disk: [OK]

6. Confirm:

/ etc/init.d/oracleasm scandisks

/ etc/init.d/oracleasm listdisks

ASMDISK1

ASMDISK2

If it is rac, you need to execute scandisks on other nodes:

Partprobe / dev/mapper/mpath2

Partprobe / dev/mapper/mpath3

/ etc/init.d/oracleasm scandisks

Scanning the system for Oracle ASMLib disks: [OK]

/ etc/init.d/oracleasm listdisks

ASMDISK1

ASMDISK2

6. Use asmca to add disks:

7. Check the progress of diskgroup data balancing:

SQL > select * from v$asm_operation

GROUP_NUMBER OPERA STAT POWER ACTUAL SOFAR EST_WORK EST_RATE EST_MINUTES ERROR_CODE
