MetroCluster/SRDF - ATM Data and Heartbeat LAN

[Ivan Pistelek]

Does HP support designing MetroCluster/SRDF cluster with ATM networking in terms of MC/ServiceGuard's DATA and HEARTBEAT LANs?

I found in HP documents that FDDI and Ethernet (10BT and 10/100BT)as well is supported in that type of environments?

What about ATM?

You cannot use ATM as a heartbeat lan. Also local lan failover and monitoring the lan's health does not work with ATM. ATM lan's cannot be included in the SG configuration file. The reason is that ATM lans do not support DLPI.

However, you CAN use ATM on a SG cluster as a data lan, but it is really configured outside of the SG configuration itself. (This is the same concept as for Hyperfabric). This is documented on http://docs.hp.com/hpux/onlinedocs/B1056-90004/00/00/26-con.html


To make SG aware of failures of an ATM lan, an EMS monitor resource for ATM is configured as a package dependency.
The ATM monitor software can also peform local recovery.
