Issue/Introduction

Created a new User Storage group from Vantage web client, then tried to edit the newly created user storage group from Vantage web client as follows:
'Hosts' selected -> 'User Storage Groups' selected -> edited active 'POOLDEFs' -> trying to edit the newly created user storage group.

Receive the following error when tried to edit.

Resolution

Please verify all the steps listed below to fix the issue:

1. Verify that in your **.PARMLIB(VKGPARMS), or any other member you use based on config member, you have either no POOLDEF, or you have
   POOLDEF  (someLetter). If there is no POOLDEF then the default is POOLDEFS.
2. Then verify you have (in the same PARMLIB) the member POOLDEFx, where "x" is the letter configured before or the default member POOLDEFS.
3. Then check this POOLDEFx member (you can view it manually) and check that the new user defined storage group is added in the POOLDEFx member.
4. Also verify that the first 16 characters in this member are: * <FORMAT_0001>.  
5. Recycle the Vantage host task and then user defined storage group is most likely should be able to edit.
