EVA4400, Oracle 10g Cluster using ASM ...

damiri — Thu, 12 Mar 2009 16:05:42 GMT

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 ?

Â¿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.

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.

damiri — Fri, 13 Mar 2009 12:02:05 GMT

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 ...

damiri — Fri, 13 Mar 2009 12:08:47 GMT

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?

Hello,

if you use Oracle metalink (which I have used now for the first time since I am not Oracle DBA), then you can come up with action plan. I can send you my action plan (which is fairly in my native language other then English but I can translate it). So here is first part:

- If you do all preparation work according to Oracle posted stuff, you do following:

- clean up both of your servers according to metalink document 341214.1
- do installation and workarounds as per 310791.1

This is scheduled to be executed tomorrow.

If you do not have access to metalink, send me a note and I will fwd to you ...

br,

Hello, we have tried this but still same. Same error with 11g but difference that Oracle cluster verify tool cluvry gives green light on installation. No warning. But still installation breaks on same place with same error.

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

JakeKn — Mon, 16 Mar 2009 09:43:18 GMT

We just finalize those metalink tasks and also stuck with same error. We also try to disable multipath to storage while installing but still no success...

damiri — Mon, 16 Mar 2009 09:51:17 GMT

Do you have any other idea what to try :-)?

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

JakeKn — Mon, 16 Mar 2009 09:54:44 GMT

We try to solve with this next metalink 276801.1

We realize that OracleCSService stays starting... I am not sure but something to try :)

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

JakeKn — Mon, 16 Mar 2009 10:15:13 GMT

Solved. We use account which we grant local administrator rights through ad group. Install clusterware with "real" local administrator. Add user straight to local administrators group.

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

damiri — Mon, 16 Mar 2009 10:20:14 GMT

I have done this, I think. However, can you lay down steps what exactly you did ?

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

JakeKn — Mon, 16 Mar 2009 10:28:19 GMT

1. We made cleanup like metalink documents says
2. Delete all raw disks
3. Add user you are doing install to local administrators group
3. Boot
4. Recreate raw devices
5. Install again

Hm, I think we tried this already. However, I will do it again, from beggining. I am glad you done it :-)))...
