PowerHA6.1 und Disk Heartbeat 1 Year, 9 Months ago  
Hallo zusammen,

ich habe da mal eine Frage zu Disk Heartbeat unter PowerHA 6.1.
Zu HACMP 5.4 Zeiten haben wir immer über den CSPOC eine concurrent VG angelegt und diese als Communication Device der Topologie hinzugefügt.

Unter PowerHA 6.1 finde ich den Dialog nicht mehr, stattdessen finde ich im CSPOC den Punkt "Manage Concurrent Access Volume Groups for Multi-Node Disk Heartbeat".
Ist dies der zu empfehlende Weg um Disk Heartbeats zu erstellen (also hätten wir dies so auch schon unter 5.4 machen sollen)?
Ist Multi-Node nur eine spezielle Form des Disk Heartbeats?
Funktionieren beide Formen des Disk Heartbeats?
Wird beides von IBM unterstützt?

Vielen Dank und Grüße aus Köln
Frank

Hallo Frank,

starting with HACMP 5.4.1 the Multi-Node Disk Heartbeat is a second possibility to implement the non-IP network in your cluster using disks. The traditional disk heartbeat is still available and you just have to select the appropriate disk of a enhanced concurrent mode VG in the topology section of the enhanced configuration.
The Multi-Node Disk Heartbeat adds a new network type to the cluster which is not accessible through the traditional smit panels. It uses a real concurrent VG and creates a raw device which is accessible by all nodes in the cluster.
If a node looses the contact to the disk a predefined failure action is called which may e.g. halt the node.

Regards
Claus

Hello Claus,

thanks for the answer. So (at this moment) it is choosable which HB implementation I want to use.
As for now we can stick with our old fashioned way.

Kind regards
Frank
