How to config the two nodes cluster?

[olive_wide]

Only two nodes,all are ES45,memory channel(connected via cable,no memory channel hub),MSA1000.
The disks in MSA1000 are only used for data disks,two nodes's operation system are installed in local disk. I want to know how to config the cluster.How to set the parameter value(votes,expected,etc).Is it needed to config the quoro disk?
Can you tell me the detail configuration?
Thank you very much.

Olive,

VOTES=1 for each node, EXPECTED_VOTES=3, QDSKVOTES=1, DISK_QUORUM="$1$DGAx:"

It makes sense to configure a QUORUM disk in this config, as it allows you to continue to run the cluster, even if one node is down.

To create the QUORUM disk (e.g. [000000]QUORUM.DAT file on the quorum disk), you have to start 2 nodes or just temporarily start one node with EXPECTED_VOTES=1. The quorum disk needs to be mounted, so that CLUSTER_SERVER can create the quorum file. See recent thread:

Volker,
Thanks for your reply.
Yes,I know how to do now.
And another question is:Is it necessary to set a quorum disk for two nodes's cluster?Is there another way to form this cluster?
The usage of two nodes:One is running all time, another one ought to be shutdown or reboot for programming,it is shutdown or reboot ,it can't effect another node.

Olive,

If I understand you correctly:

-- NODE_A should be running,
-- NODE_B may close down any time.
-- If node_B fails, NODE_A should contiue,
-- and >>> the important part <<< if NODE_A fails, there is _NO_ need to continue running with NODE_B (it enters a high-interrupt WAIT state, waiting for quorum)

If _ALL_ of these conditions are true, then you can set VOTES for NODE_A to 1 (one), and for NODE_B to 0 (zero). That makes for EXPECTED_VOTES = 1 (one).

(Effectively you will have a cluster analogues to an NI cluster with one bootnode and one satellite.)

If _ANY_ of those conditions is _NOT_ true, then you will ABSOLUTELY need a third voter (eighther a third node or a quorun disk)

hth,

Proost.

Have one on me.
