时间 2021-08-14 标签 node oracle ssh ide rest get class

配置祼设备 (2个节点操做配置相同)
节点1 祼设备配置,添加或者修改如下参数文件:
[root@node1 /]# vi /etc/udev/rules.d/50-udev.rules
KERNEL=="*", OWNER="oracle" GROUP="oinstall", MODE="0660"
[root@node1 /]# vi /etc/sysconfig/rawdevices
# Voting Disks 100M
/dev/raw/raw1 /dev/sdb1
/dev/raw/raw2 /dev/sdb2
/dev/raw/raw3 /dev/sdb3node

# OCR 200M
/dev/raw/raw4 /dev/sdb5
/dev/raw/raw5 /dev/sdb6oracle

[root@node2 /]# vi /etc/sysconfig/rawdevices
# Voting Disks 100M
/dev/raw/raw1 /dev/sdb1
/dev/raw/raw2 /dev/sdb2
/dev/raw/raw3 /dev/sdb3ide

# OCR 200M
/dev/raw/raw4 /dev/sdb5
/dev/raw/raw5 /dev/sdb6rest

# ASM Disks
/dev/raw/raw6 /dev/sdb7
/dev/raw/raw7 /dev/sdb8
/dev/raw/raw8 /dev/sdb9
/dev/raw/raw9 /dev/sdb10
/dev/raw/raw10 /dev/sdb11
---------------------------------------------------------------------
配置裸设备服务自启动:
[root@node2 /]# chkconfig --list rawdevices
rawdevices      0:off   1:off   2:off   3:on    4:on    5:on    6:off
启动raw devices 服务，确认裸设备建立成功，权限正确：
[root@node2 /]# service rawdevices restart
检查祼设备绑定状况:
[root@node2 /]# ls -la /dev/raw
total 0
drwxr-xr-x 2 root   root         240 Sep 20 12:23 .
drwxr-xr-x 13 root   root        4240 Sep 20 12:23 ..
