POWER HA 6.1 磁盘心跳配置需注意哪些事项？

对于多节点，>=3，要配置成multi-node disk heartbeat。

There are two different SMIT pathsavailable to configure a multi-node disk

heartbeat device:

Using the smitty hacmp fast path, selectExtended Configuration→

Extended Topology Configuration→ Configure HACMPNetworks→

Manage concurrent Volume Groups forMulti-Node Disk Heartbeat.



Using the smitty hacmp fast path,select System Management (C-SPOC)→

HACMP Concurrent Logical VolumeManagement→ Manage

concurrent Volume Groups for Multi-NodeDisk Heartbeat.

不过个人还是建议简单点，2个节点的HA就可以了。

注意此磁盘所在的lun上的RAID不能太忙，以防心跳丢失。

其他细节请参考《PowerHA完全手册》配置篇。
