Getting exception: A problem occurred modifying the Storage Group SRDF Group resource: Unable to acquire the Symmetrix device lock

[Sacheen123]

Hi,

Thank you for your help in advance.

I am calling API failover_storage_group_srdf() with failover_options {'failover': {'establish': True} } on my DR (secondary) site, but the API is throwing an exception: Bad or unexpected response from the storage volume backend API: Error PUT symmetrix resource. The status code received is 500 and the message is {'message': 'A problem occurred modifying the Storage Group SRDF Group resource: Unable to acquire the Symmetrix device lock'}.

The API is calling from node which is currently DR/secondary node & expected to change the roles. It is able to change the role but worrying about the exception.

I am not able to find any document describing options that can be passed as parameter in failover_options like bypass', 'star', 'restore', 'immediate', 'hop2', 'force', 'symForce', 'remote', 'establish'.

I then updated the failover_options in failover_storage_group_srdf() with remote as True: {'failover': {'establish': True, 'remote': True} }

It is now not throwing an exception, but I am not sure is it ok to use remote option in here. Please help.

Thanks, Sacheen Birhade

There is a configuration lock on these devices, this is not an API problem or issue with PyU4V. https://support.dell.com/kb/61086

Thank you very much for your reply. Do I need to wait for a configuration lock to release? If yes, what is a REST API to use? Is is ok to ignore the exception ? Unable to url https://support.dell.com/kb/61086

Sacheen, I have no idea why these locks are on your system, if you are not confident in releasing them yourself then you should open an SR with Dell Support. I have no idea if your system is in production etc so can't advise you on this via GitHub. Please open a service request and a member of Technical Support will assist.
