This post shows step by step procedure involved in creating the Disk based heart beat polling in the HACMP environment.
Heartbeat polling refer to the process of checking the TCI/IP connectivity between the nodes in the cluster.
Heartbeat polling could be configured in a TCP/IP based or non-TCP/IP based network.
When the hearbeat fails, the failover happens based on the policy configured in the HACMP.
1) Select the physical volume (common) of smallest size.
# lspv
# booinfo -s hdisk# : Command to view the size of the disk.
2) Create a enhanced concurrent volume group.
# mkvg -y disk_beat_polling -s 4 -C -n hdisk1
or
# smitty hacmp-->c-spoc-->hacmp concurrent logical volume management--> concurrent volume group--> create a concurrent volume group--> select the nodes in the cluster --> select the PVID--> enter the Volume group name and Enter.
3) Perform Discovery Hacmp Related Information.
4) Add the dish beat network.
# smitty hamp--> extended configuration--> resource configuration--> add a network to hacmp cluster --> Select the "diskhb" from the predefined serial device type and Enter.
The default TCP/IP network name : net_ether_##
The default Disk based network name : net_diskhb_##
5) Configure communication Interfaces / Devices.
smitty hacmp-->extended configuration--> extended topology configuration--> configure hacmp communication interfaces/devices --> add communication interfaces/devices--> add a discovered communication interface and devices --> communication devices -->select the nodes in the cluster and Enter.
Now perform verification and syncronization. Finally start the cluster services.
Successful configuration of disk beat polling is viewed through:
# lssrc -ls topsvcs
Look for the column which says "HB Interval; Sensitivity and Missed HB's"
