After getting the pre-requiste perl modules installed today I've repatedly tried to execute the 'Service Catalog Initialize' workflow and repeatedly get an error similar to:
Unable to contact WFA service url http://localhost:80/rest/execution/jobcommand/8f905378-3aee-421c-8cb4-ad8b1435d203 at C:/Program Files/NetApp/WFA/Perl64/lib/WFAUtil.pm line 551, <STDIN> line 1.
... at different steps within the workflow
Each one of errors comes after a 3-minute delay so I'm assuming something is timing out. I've noticed these symtoms and tried a few things:
- it is not always the same command step. The example below shows it failing on step-3 but I've also seen it run through to step-8 (Install QoS Service ) and then fail on that steps with the same error ... it has failed this way one 3 different steps at different runs (out of the fisrt 8 steps)
- wondering if a credential for 'localhost' was in play (I had one setup previously) I changed it, and finally deleted it, seeming to make no difference - is anything required in he way of a credential (localhost) for this pack?
- when running a second time I'll sometimes go into the WFA Cache DB and pre-delete (drop) all the tables it was able to create on the last run, seems to make no difference
- I've looked at workflow logs and just don't see anyting revealing
Here is screenshot of error:
I've attached
- workflow log .zip after a failure.
- log of most recent ppm installs
ENVIRONMENT:
- Windows 2008R2 Standard SP1
- WFA 3.0P1
- SLO Pack 1.1.0
This seems intermittment since it's has occured at 3 different command steps in the workflow, all with essentually the same 'Unable to connect' error following a 3-minute delay.
Ideas for things to look into? This WFA server has been in use for over a year.
Additional information:
- Uninstalled WFA 3.0P1
- Installed WFA 3.0P1 and DID NOT restore it's database
- Added OCUM data-source and a couple of credentials
- Did the three ppm installs for prerequsite perm modules
- Imported the SLO Pack 1.1.0
- Executed Service Catalog Initialize - after ~ 3-minute stall get the same error (log zip file attached)
- Went into Designer->Commands and attempted to test 1st cmd step - Create Service level Class Table - after ~ 3-minute stall get the same error
- Screen capture of stand-alone command error follows
- Also attaching Workflow execute logs where 1st step fails
More additional information:
- On a a DIFFERENT relatively new and virgin w2k8r2 server with only SnapDrive installed. WFA has never been installed on this server before.
- Installed WFA 3.0P1
- added a data-source and a couple of credentials
- Installed the 3 perl modules
- Imported the SLO Pack 1.1.0
- Executed the 'Service Catalog Initialize' workflow -- seems to have run fine !!!
So this problem is related to the original WFA Server. This WFA server ahs been in constant use for 12-18 months (inlcuding upgrades from 2.2 to 3.0, etc)
To test a possible theory that something about this WFA server can't run perl commands I do the following:
- Find a built-in cDOT WFA Perl Command: 'Create Schedule'
- Test run this command to create a type=cron schedule
- I get roughly the same error on from that command.
- Screen capture follows:
What further debug/analysis steps could I take to isolate why perl commands are failing on this WFA environment?
