MC/SG脚本问题

spring_y

如果我想在MC/SG运行前，和IP地址切换（failover）前及IP地址切换后（failback）运行一段脚本，可以吗？应该加在什么地方？谢谢
比如我想在MC/SG运行前，停掉一个进程，MC/SG运行后再启动该进程；同样在IP切换前停掉进程，切换后再启动它。

Hi,

The general steps to setup MC/SG are as following:

1. Install MC/SG on all nodes.
2. Setup cluster :
Use "cmquery" to create an ascii configuration file, then vi this file; then use "cmcheckconf" to see if there is any error; then use "cmapplyconf" to distribute the binary.

3. Setup package:
Use "cmmakepkg -p" to create a package ascii configuration file, edit, cmcheckconf, cmapplyconf; then use "cmmakepkg -s" to create a package control file, this is a shell script.

Inside this shell script, there are two functions: "customer_defined_run_cmds" and "customer_defined_halt_cmds".

The customer_defined_run_cmds can let you put any commands/scripts, same thing with the customer_defined_halt_cmds.

The sequence when a package starts:
1) activate_volume_group
2) check_and_mount
3) add_ip_address
4) customer_defined_run_cmds
5) start_services
6) start_resources

The sequence when a package stops:
1) stop_resources
2) halt_services
3) customer_defined_halt_cmds
4) remove_ip_address
5) umount_fs
6) deactivate_volume_group

I suggest you to download the "Managing MC/ServiceGuard" from HP, here is the URL:   http://docs.hp.com/hpux/pdf/B3936-90065.pdf

Good luck.

谢谢Shad，我想再请教一下，如果想在Assigns package IP addresses to the LAN card on the node.前执行自己的脚本，而不是在Executes any customer-defined run commands中执行，可以吗。谢谢
