SLES321 exercise 5-5 - crm_mon (rc=102)

yesterday I configured cluster on node 1 (exercise “5- 4 Initialize the HA cluster on node1”).
At the end command crm status returns “all ok”.

Now I’m doing exercise “5- 5 Join node2 to an existing HA cluster”
but running command crm_mon remain in stall
“Attempting connection to the cluster …”

On node1 running command
crm status
I have error:
“ERROR: status: crm_mon (rc=102): Connection to cluster failed: Transport endpoint is not connected”
Please could you help me?
Thank you in advance.

Followin link:
on node1 I ran:
sbd -d /dev/disk/by-id/scsi-360014051fdfce608104470e930c688e2 create

after rebooting node1, crm staust OK.

So everything is OK now?
