EVA4400, Oracle 10g Cluster using ASM ...

Hello,

I have setup enviroment for our Oracle people to installa Oracle RAC. This should be simple per Oracle documentation but they ran in this error I am attaching it. This is first time I am setting up something for Oracle RAC and I did presentation of shared disk to both nodes. I can see the disk from both nodes and they are accessible. Is there anything else what needs to done in order to get this working ?

├В┬┐What operating system are you using?

Normally, if you follow the correct oracle installation guide for the operating system, you should not encounter extrange problems.

Re: EVA4400, Oracle 10g Cluster using ASM ...

hm, looks like I do have some issues here with SAN configuration. I have two hosts, Windows 2003 R2 Stanard Edition, 64-bit. I create vdisk, I present it to both hosts. Both hosts are seeing this disk. However, when I create folder on one host on this shared disk, I don't see it on another. I checked domain accounts, I am using one account on both servers. For this to work, I need to have access from both servers. Any idea ?

>>> I create vdisk, I present it to both hosts. Both hosts are seeing this disk.

So far good.

>>> However, when I create folder on one host on this shared disk, I don't see it on another.

This is terribly bad. You should not even try that. To allow simultaneous access of a disk from both servers over a file system, you need a cluster file system, like veritas. Microsoft does not provides a cluster file system so you cannot access the same disk simultaneously from both nodes with a file system.

Using raw device, and Oracle, you can. That means, you must not format the shared disk.

Then Ok. If I am able to see vdisk from both servers, then SAN configuration is Ok. Then what is the problem when Oracle Assistant is saying that there is a problem with shared storage ... I have no formatted partitions ...

Or if you have experience with Oracle RAC, how to force actually Oracle installation procedure to see shared storage. Apparently this is the issue since Windows can see shared disk but Oracle RAC Assistant can't...

Hello,

Exactly same setup and we got same error 1073741819 in oracle clusterware configuration. Did you find a solution?
