以下命令序列显示了资源 VirtualIP 配置的参数的初始值、更改 ip 参数值的命令，以及 update 命令后的值。
# pcs resource config VirtualIP
Resource: VirtualIP (type=IPaddr2 class=ocf provider=heartbeat)
Attributes: ip=192.168.0.120 cidr_netmask=24
Operations: monitor interval=30s
# pcs resource update VirtualIP ip=192.169.0.120
# pcs resource config VirtualIP
Resource: VirtualIP (type=IPaddr2 class=ocf provider=heartbeat)
Attributes: ip=192.169.0.120 cidr_netmask=24
Operations: monitor interval=30s注意
当您使用 pcs resource update 命令更新资源操作时，您没有专门调用的任何选项都将重置为它们的默认值。
