NimbostratusHow to check if particular Virtual Server exists?
Hi folks,
I'm new to iControl, and I'm struggling to have few simple tasks accomplished via java:
1. check if particular Virtual Server exists
2. create new Virtual Server
3. Set basic properties
I've found an article (http://devcentral.f5.com/Tutorials/TechTips/tabid/63/articleType/ArticleView/articleId/205/iC2I-Creating-a-Virtual-Server.aspx) which prob covers some basic stuff, but I'm still not sure how to check whether the vserver exists. Is there a wrapper class similar to Pool or PoolMember?
Any help is appreciated.
Thank you, Roman

Roman_80473Hi Matt,
Thanks for replying. I'll try it and let you know ... I can't believe it's that simple
Roman- Roman_80473Hi Matt,
That worked fine, thanks. One last question though a bit off topic: do I need the def pool w members created prior to creating a virtual server? In other words, is this a correct sequence: create f5 pool -> create members -> create virtual server and set def pool along with other params (address, port, protocol, etc) ?
Thank you,
Roman - L4L7_53191That's actually a really good question, and the answer reveals quite a bit about how BigIP is setup. In short, no, you don't need to have a default pool setup. A Virtual Server is an object that you can assign a bunch of optional behaviors and attributes to - a pool is among them. From an iControl perspective, you'll probably need to specify that there's no default pool though - it doesn't handle default settings like the CLI or GUI does (which is a shame in my opinion).
-Matt - Roman_80473Got it, thanks. I think I'll be better off creating a pool w members first. Otherwise, vserver would pretty much render itself useless.
