MES数据库存储迁移Action_PROD(3)

Oracle RAC 迁移解决方案(存储迁移)

一、前期准备

1.1检查DG、OCR、VOTEDISK信息 DG 确认方法 Raw设备 Size(G)

ORADATA2 dbca /dev/raw/raw8 1000

ARCHIVE2 dbca /dev/raw/raw9 200

OCR ./ocrcheck /dev/raw/raw10 1

OCR ./ocrcheck /dev/raw/raw11 1

VoteDisk crsctl query css votedisk /dev/raw/raw12 1

VoteDisk crsctl query css votedisk /dev/raw/raw13 1

VoteDisk crsctl query css votedisk /dev/raw/raw14 1

1.2准备裸分区

存储划分磁盘到Database Server（如下表所示：） Raw设备 Size(G) 对应设备 /dm-* DG/FS

/dev/raw/raw15 1 /dev/mapper/mpath10 /dm-17 OCR

/dev/raw/raw16 1 /dev/mapper/mpath11 /dm-18 OCR

/dev/raw/raw20 1000 /dev/mapper/mpath12 /dm-19 oradata

/dev/raw/raw 1500 /dev/mapper/mpath13 /dm-20 Backup

/dev/raw/raw17 1 /dev/mapper/mpath14 /dm-21 VoteDIsk

/dev/raw/raw18 1 /dev/mapper/mpath15 /dm-22 VoteDIsk

/dev/raw/raw19 1 /dev/mapper/mpath16 /dm-23 VoteDIsk

/dev/raw/raw21 200 /dev/mapper/mpath17 /dm-24 Archive

1.3绑定裸设备（两节点执行）

vi /etc/sysconfig/rawdevices

# ocr

dev/raw/raw15 /dev/mapper/mpath10

dev/raw/raw16 /dev/mapper/mpath11

# voting disk

dev/raw/raw17 /dev/mapper/mpath14

dev/raw/raw18 /dev/mapper/mpath15

dev/raw/raw19 /dev/mapper/mpath16

# oradata

dev/raw/raw20 /dev/mapper/mpath12

# archive

dev/raw/raw21 /dev/mapper/mpath17
