查看scanip配置信息

使用grid用户在目标节点上执行srvctl relocate进行切换

scan -i 1 -n rac1cen指的是scan number为1，节点主机名为rac1cen

[grid@rac2cen:/home/grid]$ srvctl config scan 1

SCAN name: raccen-scan, Network: 1 2

Subnet IPv4: 192.168.75.0/255.255.255.0/ens33, static 3

Subnet IPv6: 4

SCAN 1 IPv4 VIP: 192.168.75.114 5

SCAN VIP is enabled. 6

[grid@rac2cen:/home/grid]$ 7

手动切换scanIP

scan -i 1 指的是“srvctl config scan”中的scan number（当前为1）

su - grid 2

srvctl relocate scan -i 1 -n rac1cen3
