Hi Sutanu,

Before installation of version 2.0 of plug-in, please ensure that you have uninstalled version 1.0 of plug-in and removed all the associated storage targets.

Even if you have un-installed version 1.0 plug-in earlier, please try to deploy the plug-in again.

Please let us know if it works.

Regards,

Sachin Maheshwari

Hi Sachin,

It was a fresh new install of 2.0 and we didnot have any other 1.0 plugins at that time, so, pls advise on the errors.

Is 2.0 plugin certified with 12c 1.0.1.1 OMS version?

All pre-req checks were successfull too

[sachin1]

Hi Sutanu,

Thank you for information.

I would still recommend you try to do installation one more time.

Also, are you facing this error at the time of metadata registration during plug-in deployment (step  9 or 8)?.

We will check for plug-in installation failure with Oracle Team as well because plug-in installation is taken care by OEM.

Can you also please send the logs generated at following path: (emctl.log, emoms.log)

/<OMS_MIDDLEWARE_PATH>/gc_inst/em/EMGC_OMS1/sysman/log

Regards,

Hi Sutanu,

Thank you for sharing the information. We are able to reproduce the issue and it is having same problem in my setup for OEM version 1.0

Ideally, plug-in should be supported on OEM version 1.0. We will check with Oracle also.

What we can suggest you here: If it is possible, please upgrade your OEM setup to 2.0 and start using version 2.0 of NetApp Storage plugin.

Please write to us for any queries.

Regards,

Sachin Maheshwari

Hi Sachin,

Good to hear you are able to reproduce this. OEM 1.0 to 2.0 upgrade is bit involved

1. Is it possible to request your pluging development team to fix this?

2. Is it possible to replace the 2.0 plugin file with 1.0 plugin file netapp.storage.sys.oms.plugin_12.1.0.2.0/metadata/reports/CsAggregateUtilization.xml ?....

3. I did 1.0 plugin deployment but it didnot discover anything on our cluster 8.1 ontap

pls advise 1, 2, and 3

[sachin1]

Hi Sutanu,

Please find the comments below:

1. We are discussing this version problem with Oracle. Based upon their response, we will update you. You may need to wait till Oracle reverts.

2. We can't replace the files for 1.0 with 2.0. It will not work.

3. Plug-in 1.0 will not discover any thing for Clustered Data ONTAP because we have introduced support for this in version 2.0.

In the mean time, If it is possible, Try to install OEM version 2.0 in your dev environment and start Monitoring Clustered Data ONTAP version and do share your feedback.

Question - Is your netapp plugin 2.0 works for OEM 3 (12.1.0.3)?

the Oracle OEM upgrade process is complex from going from OEM 1.0 to either OEM 2.0 or OEM 3.0 (latest) so if we upgrade we will upgrade OEM 3.0 but asking if your plugin will work?

Your documentation of netapp plgin 2.0 says it works for 12c Release 1.0 or later and for sure, you documentation is wrong.

[sachin1]

Hi Sutanu,

Yes, NetApp Storage Plug-in version 2.0 works for OEM 3.

We are working for the problem of version 1.0 support of Plug-in 2.0 and interacting with Oracle Team as well. It looks like during development of the plug-in one should use a specific version string of OEM which may solve the problem we have here. We also have to resolve a combination of EDK (developers kit) version dependency also – hence we will get back to you soon on the stand on whether 2.0 works with 12C release 1.0 or not. Thanks for your support – please wait for further updates.

Regards,

Sachin Maheshwari

[sachin1]

Hi Sutanu,

We have identified this problem after having discussions with Oracle and it was an "OMS_VERSION" string issue because of different EDK versions used. We will provide this fix in next patch release of plug-in. Patch release has been planned tentatively either around 24th Dec 2013 or mid of Jan 2014.

With this update, we confirm the support of Plug-in version 2.0 for OEM version 1.0.

We appreciate your valuable inputs and feedback.

Hi Sachin,
