MSCS Support with SP2

[sc_2111]

I know that Windows 2003 SP1 has been recently added as supported for MSCS configuration , with the installation of a patch or ESX3.02. Does anyone know anything about SP2 ?

Also I've read in HP documentation that MSCS is not supported with 4GB HBA , is that true ?

Thanks

MSCS is \*ONLY* supported on LOCAL storage, that's why the HBA is not supported.

SP2 / SP1 makes no difference.

The OS of clustered nodes are supported on LOCAL storage , however the clustered LUN are by definition on SAN ....

Parker, the shared disks are located on the SAN, that is why we certify the HBA.

SP2 and 4 gbit HBA drivers are currently under testing for 3.0.2,

the MSCS white paper will be updated then finished.

Hello Anders ,

so can you confirm no support for MSCS with 4Gb HBA ?

Do you have any idea when , if , they wil be supported ?

thanks

Hello Anders ,

Yes, certification is not finished.

Do you have any idea when , if , they wil be

supported ?

Yes, we have internal estimates, but nothing I can share.

Our goal is to certify in 3.0.2, if we find bugs that might slip.

Hello Anders,

might I ask you to post an update when the certification will be available ?

We've already installed 3.02 so we'll wait for the formal certification to proceed with the customer planned configuration

Thanks

Is it not supported for both RDM and Virtual disk? Does anyone know what is the cause, can you create the cluster and not have locks on the disk so it is a potential corruption issue? Curious since esx presents a scsi disk to the vm, how would the clustering service know what the underlying hardware is?

Clustering IS supported. What is not supported is clustering with 4Gb HBA.

There was , in past , a problem with 2003 sp1 ( which was not supported in cluster configuration ) but since a patch released for esx3.01 it's fully supported .

I saw it a few days ago , but pay attention to the SAN guide.

4Gb HBA are not supported with all storage but only with a subset of it.

For example is only supported with EVA8000 and not with 4000-6000
