Some workflows stopped working after WFA upgrade

Hi All,

 

I've a problem with a workflow after I've updated WFA version from 4.1 to 5.0.1.  An user input query which select a snapshot drops an error when I wanted to modify/save the workflow:

Addionally I have a Acquire data source" and “Wait for data source acquisition” fail error, but I will try this souliton suggested here: https://kb.netapp.com/app/answers/answer_view/a_id/1087616

 

But right now I'm not able to save it because of the above mentioned error.

What do you Guys suggest?

 

Many Thanks

Zoltan

Re: Some workflows stopped working after WFA upgrade

Hi Zoltan,

 

On your WFA5 server do you have the pack\datasource configured for the "cm_storage_smsv" schema? Can you run the query externally to WFA? EG via something like HeidiSQL https://www.heidisql.com/download.php download the 64 bit .exe and copy it to your MySQL lib directory then connect as the default read-only WFA database user (Usr: wfa. Pwd: Wfa123).

 

Is it possible you need to install the "Manage SnapMirror-SnapVault Cascade Relationship - Version 1.0.0" Pack on your WFA5 server? https://automationstore.netapp.com/pack-detail.shtml?packUuid=ba11fac4-9710-4f2b-90ed-a7efbd4e723a&packVersion=1.0.0 

 

Also additionally you might want to check there are no issues with snapshot timestamps and timezones in your environment:

Hope that helps? Please let me know if you have any questions?

Re: Some workflows stopped working after WFA upgrade

Hi Matt,

 

Thanks for suggesting HeidiSQL, I've just wanted to get some sql tool to test. With this I was able to  run the query, (only with root user, wfa read olny user drops access denied)

 

So I am able to ask snap from db with this tool with sql root user:

But Wfa drops error when try to test it:

I've checked sql user table and this is what i have:

Is this looks ok?  wfa user does not have any right. 

I also cheked on a fresh clean install of wfa 5.0.1, and the user table is same ase here.

What do you think?

 

Thanks

Re: Some workflows stopped working after WFA upgrade

Hi Zoli

 

Okay the WFA snapshot pack installed on WFA5 and your query works successfully as root. What's the output of:

 

SHOW GRANTS FOR 'restricted'@'localhost';

Is it possible the "restricted" database user does not have appropriate permissions the "cm_storage_smsv" database???

If the result is that the user does not have to permission connect to MySQL as root and  grant permissions:

 

GRANT ALL PRIVILEGES ON cm_storage_smsv.* TO 'restricted'@'localhost';

 

Note: The above command will grant full control to the database, that might not be appropriate for your environment.

Assuming you limit access to the "restricted" user (IE SELECT read-only) then...

 

GRANT SELECT ON cm_storage_smsv.* TO 'restricted'@'localhost';

Does that fix the problem?

Re: Some workflows stopped working after WFA upgrade

Hi,

 

for the "Acquire data source" issue there is a better solution than the workaround mentioned in the KB. NetApp released an update of the "WFA pack with common entities" in the Automation Store.

Re: Some workflows stopped working after WFA upgrade

HI Guys,

 

@mbeattie  sql command solved the permission problem for snapshots. Thanks!

@moep  thank you for suggestion, imported DAR!

 

Many thanks again, I think WF now will be ok, I'll get back to you when we are executing it next time!

Re: Some workflows stopped working after WFA upgrade

Hi Guys,

 

Unfortunatelly I still have some problem with data aquisition.

 

I get the following error when the Refresh Environment wf running:

 

03:37:04.127 ERROR [Wait for data source acquisition] Wait Command failed for Workflow 'Refresh Environment' with error : could not find ParserDetails.ini in C:/Perl64/site/lib/XML/SAX

 

Do you have any suggestion what to check?

 

Many Thanks

Re: Some workflows stopped working after WFA upgrade

Hi Zoli,

 

I hit the same issue for a customer. The solution i chose was not to use PERL and instead rewrite the commands to acquire the datasource and wait for datasource acquisition via the REST API using PowerShell. Here is the command code i used:

 

acquire_wfa_datasource:

 

Param(
   [Parameter(Mandatory=$False, HelpMessage="The Protocol name")]
   [ValidateSet("https","http")]

   [String]$WfaServer,

}
#'------------------------------------------------------------------------------

Re: Some workflows stopped working after WFA upgrade

Hi,

 

Also this function might be useful for enumerating the WFA FQDN. Call it with quotes. EG: get_wfa_fqdn('')

 

def get_wfa_fqdn(hostname){
   import java.net.InetAddress;
   InetAddress addr = java.net.InetAddress.getLocalHost().getCanonicalHostName();
   return toLower(addr);
}

You need to ensure that there is a WFA Credential added which has the admin role to authenticate the REST API request to acquire the datasource. EG if your WFA server FQDN is 'wfa.netapp.com' then you need to add a credential using the FQDN 'wfa.netapp.com'.

 

Hope this helps
