關於Redhat AS 3.0 cluster的heartbeat的問題

請教：
我最近按照七月飛雪的文檔安裝設置了在redhat AS 3上的cluster. 文中提到了要在兩台機器上分別安裝設置一個用於heartbeat的網卡。但是我安裝后，發現在設置HA的時候，沒有用到這兩個網卡，只是選擇是用broadcast還是multicast heartbeat。同時我發現在/var/log/messages中出現很多這樣的錯誤信息：
Kernel: sent error broadcast ICMP to eth1 (eth1是心跳網卡,具體錯誤信息記不得了)。
請問這是為什麼？在什麼地方可以規定cluster使用eth1作為heartbeat?
(veritas cluster在安裝的時候可以設置規定那幾個作為heartbeat).

頂一下

還要更改HOSTS文件,還有其它的一些設置..

設置心跳地址

其它的都是REDHAT自己就可以認出來的..

heartbeat 就是你寫 member 時用的那個hostname 對應的網卡呀!

七月飛雪：照你這麼說，redhat cluster在設置的時候，不用指定心跳網卡地址？為什麼我的/var/log/messages文件里很多這種信息：
Aug 27 18:11:49 tst1 kernel: 192.168.0.68 sent an invalid ICMP type 11, code 0 error to a broadcast: 192.168.0.255 on eth1.
192.168.0.68是lan地址，eth1是心跳網卡。

q1208c：我仔細看了看redhat的文檔，輸入的應該是lan的地址而不是心跳的地址。

嘿嘿，  那是你沒看好。再好好看看。

First of all, I thank you for your response. I will try your suggestion.

Second, I have read the doc for ten times. It clearly states: Enter the name or address of a system on the CLUSTER SUBNET. Note that each member must be on the same subnet as the system on which you are running the Cluster Configuration Tool and must be defined either in DNS or in each cluster system's /etc/hosts file. ( I think CLUSTER SUBNET means the subnet that connects with both LAN interfaces of two nodes).

Below is the step-by-step of adding a member to a new cluster copied and pasted from redhat web site:

1. Ensure that the Members tab is selected and click New. It prompts for a member name.

2. Enter the name or address of a system on the cluster subnet. Note that each member must be on the same subnet as the system on which you are running the Cluster Configuration Tool and must be defined either in DNS or in each cluster system's /etc/hosts file

3. The system on which you are running the Cluster Configuration Tool must be explicitly added as a cluster member; the system is not automatically added to the cluster configuration as a result of running the Cluster Configuration Tool.

4. Leave Enable SW Watchdog checked. (A software watchdog timer enables a member to reboot itself.)

5. Click OK.

6. Choose File =>; Save to save the changes to the cluster configuration.

I think I found why there is error message like this: Aug 27 18:11:49 tst1 kernel: 192.168.0.68 sent an invalid ICMP type 11, code 0 error to a broadcast: 192.168.0.255 on eth1.

Because in VMWare, both eth0 and eth1 are actually in the same subnet.

第幾塊網卡做heat，有什麼關係嘛？
