We have some legacy hardware and we are about to use it to start testing the cloud platform as a proof of concept.
Basically, we have a spare EMC array, a couple of FC Switches and two old servers with their respective HBAs connected to the EMC array. All of this was part of an old two-node failover SQL Server Cluster. Servers are VT enabled and are in general fine for just testing.
I have read the installation manual and, for the moment, prior to installing, we have a question with regards of the FC storage; and the order of installation in case of XenServer hosts usage.
As per the guide (7.8 "Primary Storage Setup for XenServer") FiberChannel must be confiogured separately and Primary Storage should be added later.
Which is the proper order to add XenServer hosts and FC shared storage amongst these hosts?.
Is the XenServer pool created when the first host joins a cluster (first one being the pool master).?.
I understand that the full process is:
1. Install Xenserver hypervisors (Chapter 7) 2. Add XenServer hypervisors to the CloudPlatform Cluster (Cluster<Pod<Zone) 3. Configure FC on the XenServer host pool master. 4. Configure FC Storage (PreSetup, Chapter 6.6).
> Is the XenServer pool created when the first host joins a cluster (first one being the pool master).?.
Yes, XenServer pool gets created when you add the first host to Cloudstack and it assumes the role of the pool master. This is similar to when adding XenServer hosts to XenCenter for management.
The steps you've provide look correct and should work. Just make sure the SR are configured correctly on the XenServer pool before it is added as primary storage to Cloudstack.
