Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Roman Plevka 2019-05-07 08:45:38 UTC
Description of problem:
passing invalid parameter value for compute_attribute parameter is not always handled correctly.
e.g. on creating VMWARE host using api, we're passing:

"scsi_controller_type=VirtualLsiLogic"
instead of (correct):
"scsi_controller_type=VirtualLsiLogicController"

- the attr. value is accepted just fine, but it results in the orchestration failure later in the flow:

"2019-04-28T04:11:04 [E|app|c38a5507] Unprocessable entity Host::Managed (id: new):
  Failed to create a compute MWAVldqBnE (VMware) instance vyfaufcjln.foo.bar.com: undefined method `new' for nil:NilClass"

- it would be fine to implement the input validation with some upstream tests.

Version-Release number of selected component (if applicable):
6.5.0 snap#26


Steps to Reproduce:
1. just POST to /hosts (in my example we used VMWARE compute resource) with some invalid compute_attribute (in our cae it was "scsi_controller_type"
2. observe the production.log


Actual results:
"  Failed to create a compute MWAVldqBnE (VMware) instance vyfaufcjln.foo.bar.com: undefined method `new' for nil:NilClass"

Expected results:
A proper error message is thrown early in the process.

Additional info:

Please, implement a set of tests upstream to test input validation

Comment 13 Marek Hulan 2019-06-11 13:50:09 UTC
Ondrej, could you please take a look?

Comment 15 Jitendra Yejare 2019-06-12 09:39:04 UTC
Hey Ondrej,

Basically, I tested this bugzilla using Nailgun and hence in my comment 11 you can see this :

```
In [38]: vcp.compute_attribute[0].read().vm_attrs['scsi_controllers']
Out[38]: [{'type': 'abcd', 'key': 1000}]
```

where vcp is Compute Profile nailgun object. So above it shows that I set the 'scsi_controllers' type to 'abcd' which.

And then with that type I attempted to provision and it just failed with same error.


So If I test with correct 'scsi_controllers' type as 'VirtualLsiLogicController' the provisioning works.

Comment 16 Ondřej Ezr 2019-06-12 11:36:22 UTC
Ok, so you have the scsi_controller defined on the Compute Profile.
This BZ were not addressing such case as that have never worked.
This only addresses the 'scsi_controller_type' API attribute - mainly passed from hammer (directly to `host create` command).
It should be part of RFE for validation of Compute Attributes.

Sorry for bit misleading Title and description.

Comment 18 Jitendra Yejare 2019-06-13 08:16:32 UTC
Hello Ondrej,

This time I am getting some weird error:

```
# hammer host create --name vmhammer --compute-resource-id 1 --hostgroup-id 1 --location-id 2 --organization-id 1  --root-password passwd --compute-attributes "scsi_controller_type=VirtualLsiLogicController" --volume "datastore=Local-Ironforge,mode=Persistent,size_gb=10,thin=true" --compute-profile-id 4
Could not create the host:
  Failed to create a compute vmware_cr (VMware) instance vmhammer.satqe.lab.eng.rdu2.redhat.com: InvalidController: The device '1' is referring to a nonexisting controller '1,000'.
```

I can share setup with you if you want to debug.

Comment 19 Ondřej Ezr 2019-06-18 00:51:15 UTC
Hi Jitendra,

this error is due to a controllers are explicitly empty in compute profile.
This has never worked and doesn't work without the attribute eighter and thus cannot be considered a regression.

Would be lovely to work though and I have filed a separate BZ for that - see BZ 1721334, but I do not consider it as part of this BZ.
This is only about badly spelled controller type made the command to fail, but the correct value have not.

Comment 20 Jitendra Yejare 2019-06-19 06:56:14 UTC
Verified!

@Satellite 6.6 snap 7


Steps:
----------
1. Post hammer request to create a host with custom SCSI controller Type:
# hammer -d host create --compute-attributes "cpus=1,corespersocket=1,memory_mb=1024,cluster=Satellite_Engineering,path=/Datacenters/RH_Engineering/vm/QE,guest_id=rhel7_64Guest,scsi_controller_type=VirtualLsiLogicController,hardware_version=Default,start=1" --compute-resource-id 1 --hostgroup-id 1 --interface "compute_network=qe-sat6-feature-rhel7,compute_type=VirtualVmxnet3" --location-id 2 --name="bugverify" --organization-id 1 --provision-method="build" --pxe-loader="PXELinux BIOS" --root-password="dog8code" --volume="name=Hard disk,size_gb=10,thin=true,eager_zero=false,datastore=Local-Ironforge" 


Observation:
-------------
1. The host request is submitted with "scsi_controller_type"=>"VirtualLsiLogicController" successfully.

INFO 2019-06-19T02:47:39 HammerCLIForeman::Host::CreateCommand] Called with options: {"option_root_password"=>"***", "option_puppetclass_ids"=>[], "option_overwrite"=>true, "option_compute_attributes"=>{"cpus"=>"1", "corespersocket"=>"1", "memory_mb"=>"1024", "cluster"=>"Satellite_Engineering", "path"=>"/Datacenters/RH_Engineering/vm/QE", "guest_id"=>"rhel7_64Guest", "scsi_controller_type"=>"VirtualLsiLogicController", "hardware_version"=>"Default", "start"=>"1"}, "option_volume_list"=>[{"name"=>"Hard disk", "size_gb"=>"10", "thin"=>"true", "eager_zero"=>"false", "datastore"=>"Local-Ironforge"}], "option_interface_list"=>[{"compute_network"=>"qe-sat6-feature-rhel7", "compute_type"=>"VirtualVmxnet3"}], "option_location_id"=>2, "option_organization_id"=>1, "option_compute_resource_id"=>1, "option_hostgroup_id"=>1, "option_name"=>"bugverify", "option_pxe_loader"=>"PXELinux BIOS", "option_provision_method"=>"build"}

2. The host is created
