NEED TO CLUSTER JUST TWO rp5450's

[HP RX4640]

Hello All,

I need to set up a cluster using the following hardware and i'm not sure if it will work properly. I'm also not sure exactly what software is needed other than Serviceguard?

2 x A5191B rp5450 Servers
4 x A6146A 550MHz CPU's - 2 in each 0
2 x A5796A PSM - 1 in each
4 x A5198A 1GB Memory kits - 2 in each
4 x A6110A 36GB 10K Disk - 2 in each
2 x A5557A DVD-ROM - 1 in each
HP-UX 11.11

Any help will be appreciated I can't get any help by call HP because although I am and Authorized HP reseller I am not yet qualified as an Enterprise reseller.

Thank you in advance,
Jim

You will need at least two NICs and a shared disk device in addition. And of course Serviceguard licenses.
Here are the docs http://docs.hp.com/en/ha.html#Serviceguard

But be aware it takes some more than some clicks and keystrokes to configure a cluster.

Hi,

I totally agree with the above reply, you need a shared storage and two NIC cards (to configure failover), since MC Service Gaurd is normally configured to make a system/application highly available it would be better to contact a professional from HP to do this activity rather tying to do R & D.

Configuring and Managing a MC Cluster is not as easy as thought :--), sincere advice is to take help from HP.

The above link should give you some information on SG

Hi Jim,

The answer depends on requirements for the system. If you need really production cluster and not a test configuration, so the needed HW configuration is:
1. An external disk storage with two SCSI/FC controllers
2. 4 NICs per computer ( 2 for main network and 2 for heartbeat )
3. Two SCSI or FC connectors per machine

If you need a test configuration, so you may have only one network connection per machine and ut's possible to use internal disks for shared device.

All these requirements are for Service Guard.
