HACMP 5.4 的磁盘心跳线-LV?
在一个帖子看到老农说:
HACMP5.4,支持一种新的多点心跳,几个节点可以共用一个LV做心跳。
这个是指用LV吗?
我在一个机子上看到
Device Name abc_hdisk2
New Device Name [abc_hdisk2]
* Node Name abc +
* Device Path /dev/hdisk2
Network Type diskhb
* Network Name [abc_diskhb] +
然后lspv hdisk2 看到这是属于一个concurrent VG的. 也是一个共享的VG.
lspv -l hdisk2
hdisk2:
LV NAME LPs PPs DISTRIBUTION MOUNT POINT
lv 480 480 108..108..107..108..49 /shareapps
不知道老农说的是不是就是这样, 但是我想问一下, 创建这个diskhb的时候, device path是随便指定一个pv的吗? 只要这个pv所属的VG是concurrent 的就可以?
还有, 上面的例子中, disk2中根本没有建立什么heart beat的lv...
有没有人可以解答下, 谢谢.

不浪费啊。你把这个disk设置的小一点不就可以了。当然了,你的storage要不支持raid也没有办法。就只能用一块盘的容量了。

I think I understand:
from redbook:
Device Name A device file name. RS232 serial devices must have the device
file name /dev/ttyn. Target mode SCSI serial devices must have
the device file name /dev/tmscsin. Target mode SSA devices
must have the device file name /dev/tmssan. For disk
heartbeating, any disk device in an enhanced concurrent volume
group is supported. It could be an hdisk or vpath, for example,
/dev/hdiskn (n is the number assigned in each device file name).
Any shared disk in an enhanced concurrent mode volume group can support a point-to-point heartbeat connection. Each disk can support one connection between two nodes. The connection uses the shared disk hardware as the communication path.
An enhanced concurrent mode disk that participates in only one heartbeat network.
Keep in mind the following points when selecting a disk to use for disk heartbeating:
A disk used for disk heartbeating must be a member of an enhanced concurrent mode volume group. However, the volume groups associated with the disks used for disk heartbeating do not have to be defined as resources within an HACMP resource group. In other words, an enhanced concurrent volume group associated with the disk that enables heartbeating does not have to belong to any resource group in HACMP.

这是磁盘心跳,不是多点LV心跳。
