RHV-M requesting four GetDeviceListVDSCommand when editing storage domain
Last modified: 2018-05-10 17:44:04 EDT
Description of problem:
When we click on Manage domain , RHV-M is requesting 4 GetDeviceListVDSCommand with same arguments on the same host. The whole process can take around 1-2 minute in an environment with large number of LUNs.
For the customer, it was taking around 90 seconds in a host which is having 181 LUNs. Each GetDeviceListVDSCommand was taking around 15-20 seconds (Expected with large number of LUNs). The customer is using RHEV 3.6 and I can see 6 GetDeviceListVDSCommand however it's reduced to 4 in 4.1.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Click on manage storage domain and find the GetDeviceListVDSCommand executed in the engine log.
Editing storage domain can take some time to show up if the host is having large number of LUNs.
If all the calls are same, issue only 1 call while clicking edit storage domain.
