BMR and Oracle Linux Server 5

I cant prepare to restore OracleLinuxServer 5.

NBU 7.1.0.3 running in W2008R2 + BMR BootServer Windows + 1 Linux RedHat 5.7 NBClient 7.1.0.3 BootServer (for linux distro), SRT is redhat 5.7 (not oracle linux server) documentation describe can restore Oracle with srt Redhat 5.7

I backup Linux + BMR without problem.. but cant prepare to restore bmr... i attach error.

Your error is there then: Srt

Your error is there then:

Srt has an older kernel version. srtKernelVersion=2.6.18-274.5, clKernelVersion=2.6.32-200.13.1.5

It does not feel that your SRT is at a high enough level for this client

There are two messages given

There are two messages given by bmrprep.

First is regarding SRT OS kernel version mismatch. This is just a warning message. You can ignore this.

The other one is actual error message where BMR Boot server failed to make SRT ready for the client restore. Looks like you are doing NW based restore. BMR NW boot restore requires NFS daemon and TFTP service running on your Linux BMR boot server. Please make sure these services are up.

You can refer BMR boot server debug logs for more information.

Thanks.

I see this.

NFS Deamon is running,  put and get files without problems from NBU to linux boot server

TFTP server is running,  put and get files without problems from NBU to linux boot server

i see this error in log....

As I mentioned earlier, the problem is not due to kernel version mismatch. It is just a warning message put by BMRPREP.
Actual problem is happened at BMR boot server side while allocating SRT. If the required NW services are up then the problem might be something else. But to figure that out you need to provide BMR boot server side (119/bmrd) debug level 6 log. Above log is bmrprep log which is not sufficient to diagnose the issue.
 
Thanks.

You should look at the logs

You should look at the logs as suggested by Mandar, but it could be name resolution on the Boot Server.  If it cannot resolve the client IP or hostname, it will fail to allocate the SRT.  Once you get past the SRT allocation issue, the restore will probably work in spite of the warning, unless you are using a file system flag or option available in the OS of the system but not supported by the OS of the Linux SRT.  You can always make an ISO image of the SRT and use that to boot your client, avoiding NFS and TFTP issues.

You should also make another SRT with an updated kernel version, but even if that is at the right level, the SRT still might not be able to be allocated until that issue is fixed.
