APIs SDKs and Xen-ng
- 
 @vahric-0 You're saying that it worked in one instance but failed in a prior attempt? Did something change in the environment in between the attempts? Was the vlan in use by any VMs? 
- 
 @Danp No, vlans was created only for test no any vm is attached 
 XO should not say to me this is used , you can not delete it ?
 why its generating HA_IS_ENABLED message ?
- 
 @vahric-0 Sorry, but I'm not sure that I understand your setup. Perhaps it would help if you restated the issue making sure to address the following items -- - Is HA enabled on your pool?
- Are you able to delete the VLAN using XOA web interface?
- Are you able to delete the VLAN using XOA API?
- etc
 
- 
 HA is enabled for the pool 
 After first creation network via api , i can not deleye it from gui
 i did not tried delete vlan via apiI will try to reproduce 
- 
 yeap , i did it again  
- 
  
- 
 @vahric-0 It is recommended to disable HA whenever you are performing maintenance (adjusting networking, applying updates, etc) on your pool. 
- 
 @Danp if this is the rule , what i can say. 
 I will try one thing more because to create xostore step by step I shutdown servers and add disks after that i could delete the network
- 
 @vahric-0 I didn't understand what you were trying to say above. Are you unable to temporarily disable HA to perform maintenance? 
- 
 @Danp No of course i can disable it , okay i will not struggle with it 
 After disable HA , i could delete it , thanks
