Database is not on NFS mounted storage. Hence, no views available.

[MARTIN_LAUSCH]

Hi,

yesterday I installed the NetApp Storage Plugin in our Test Cloud Control environment.

Everything works fine so far but under the (for us - the dba team) interesting link "Consolidated Database Storage Performance" we face the Info: "Database is not on NFS mounted storage. Hence, no views available."

All(most) of our databases run on NFS storage(more exact directNFS is enabled).

Database Version: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

Database Server OS: Oracle Linux Server release 6.2

Clound Control Version: Oracle Enterprise Manager Cloud Control 12c Release 3 - 12.1.0.3.0 (db-plugin version 12.1.0.5.)

Cloud Control Server OS: Oracle Linux Server release 6.2

NetApp Plugin Version: NetApp Storage System Plug-in - netapp.storage.sys - 12.1.0.2.0

Any ideas how to get it work?

Thanks & regards,

Martin

Hi Martin,

Thanks you for sharing feedback.

Please make sure that following things have been configured:

1) Monitoring database has already been registered with Oracle Enterprise Manager (OEM)  and it is visible from there.

2) Storage controller on which database resides has also been registered with OEM.

***3) Please make sure that on database host, fstab entry holds the IP address of storage controller for mount point definition. We are using database host fstab entry to generate mapping based upon IP address (only IP address). Also, database should be mounted on NFS volume (no qtrees)

4) If you are making any changes to fstab entry now, it takes approx. 24 hours to reflect this value in OEM repository or may need to do some force operation to reflect the change.

5) Please also check if your database volumes are listed by "Volume Details" metric for the registered storage controller.

If above steps are in place, database views should work for you.

Please let us know your feedback.

*** Please note that we are working upon next release and where we have resolved that IP address constraint and you can provide short name / FQDN of storage controller in FSTAB mount point definition.

Sachin Maheshwari

Hi Sashin,

thanks for your fast answer. I will check these points.

• What I can already say is that we have several qtrees at the moment.
• Additionally we use nested mounts for the oracle binaries (some weeks ago we learned that there are some problems with nested qtree mounts and that we should change some mountpoint-options for these mounts) but I don't know if we have to care about the binaries here.
• In the fstab we use the name of the storage and not the IP

We know that we use a lot of mountpoints and volumes and we already going to change this because we start using the Snapmanager for Oracle and therefor we have to create a new structure. But for now this is the standard.

Regards,

Martin

Hi Martin,

Thank you for sharing details. Currently, we don't support views if database resides on qtrees.

From above data, I can see that databases are residing on qtrees. We are already working upon this requirement and it will be available in next patch release for database support on qtrees,

I also request, if you can share the output of following SQL. This will help us to know your environment better. If you feel data is private, please send an email: sachin1@netapp.com

You must have permissions to login to EM12c repository SQL prompt and execute below SQL on EM repository. 

SELECT V2.TARGET_NAME "DatabaseName", V1.FILESYSTEM "FileSystem", V2.FILE_NAME "FileName"

FROM MGMT$STORAGE_REPORT_NFS V1, MGMT$DB_DATAFILES V2

WHERE V1.MOUNTPOINT = V2.OS_STORAGE_ENTITY and V2.TARGET_NAME ='<DB_NAME>'   -- Specify database name here

Regards,

Sachin Maheshwari

[MARTIN_LAUSCH]

Hi Sachin,

I will send you a mail with the output of the SQL next week.

Because of qtrees. As already said due to SMO storage redesign we try to move out most of the qtrees. I can test it with a SMO test database and see if it works with a db without qtrees.

But for now it seems not usable for us for the existing systems until we reconstructed the mountpoints or we have to wait for the next release of the plugin.

Thanks so far and regards,

Martin

Hi Martin,

Thank you for update.

Version 2.0 of plug-in has lots of new features. Please review the documentation to know more and share your feedback about other features.

I also suggest when you are creating test database, please provide IP address instead of storage name in fstab for mount point definition to make this work.

Probably, we will make patch release during Jan-Feb time frame to resolve naming and qtrees dependency.

Hello Sachin,

We are on EM12c Release 3 (12.1.0.3.0) and installed the NetApp plug-in (12.1.0.2.1). Our FSTAB looks like this

rdnetapp01adata&colon;/vol/ndatmsod_data01     16777216  8187840   8589376  49% /ndatmsod/oradata01

rdnetapp01adata&colon;/vol/ndatmsos_data01     16777216  8184320   8592896  49% /ndatmsos/oradata01

1. We are using DNS name in the FSTAB

2. We are mounting the volume (not qtrees)

3. When I click on "Consolidated Database Storage Performance", I see a list of databases (How does it build the list of DBs ?)

We also edited the StorageIPAddressMapping.xml file and added the shortname "rdnetapp01adata", but still get the same error "Database is not on NFS mounted storage. Hence, no views available."

[nkarthik]

Hello Naveen,

1. Can you please send us the StorageIPAddressMapping.xml?

2. Can you send us the "nslookup  rdnetapp01adata"?

3. If you update the fstab now, please wait for 24 hours to check the change.

Hello Naveen,

In the StorageIPAddressMapping.xml, The IP address is pointed to "10.230.1.43" and in the Nslookup the Address is "10.230.1.132" for "rdnetapp01adata" and make sure the interface name is e0M for "rdnetapp01adata" " pointing IP address.

when did you update the /etc/fstab file with the following entries?, if they are updated recently wait for 24 hours to view the changes.

rdnetapp01adata&colon;/vol/ndatmsod_data01     16777216  8187840   8589376  49% /ndatmsod/oradata01

rdnetapp01adata&colon;/vol/ndatmsos_data01     16777216  8184320   8592896  49% /ndatmsos/oradata01

Please let me know how it goes now with the latest changes?

Karthik,

Do I need to restart the agent ? Still getting the error.

[NAVEENGARG]

In the /u01/app/oracle/product/agent/plugins/netapp.storage.sys.agent.plugin_12.1.0.2.1/scripts/data/7mode directory, I don't see a directory for 10.230.1.132. I was expecting that !

[NAVEENGARG]

I forgot to reply the question you asked in this post.

The FSTAB entries haven't changed in weeks.

Also, I have two lines in the StorageIPAddressMapping.xml file for this shortname with different interfacename. Is that OK ?

<InterfaceMappingInfo shortname="rdnetapp01adata" fqdnName="rdnetapp01adata.ctdi.com" ipAddress="10.230.1.132" interfaceName="e0M"/>

<InterfaceMappingInfo shortname="rdnetapp01adata" fqdnName="rdnetapp01adata.ctdi.com" ipAddress="10.230.1.132" interfaceName="nfsdata01a"/>

[nkarthik]

Naveen,

Try restart the agent and check /u01/app/oracle/product/agent/plugins/netapp.storage.sys.agent.plugin_12.1.0.2.1/scripts/log/NetAppPlugin.log and send it to nkarthik@netapp.com and sachin1@netapp.com
