Hi,<br>
<b><br>
</b><b>Can we share the iSCSI data storage domain across multiple
clusters in the same datacenter?</b><br>
<br>
Following are the setup details which I tried.<br>
<blockquote>- One datacenter, Say DC1<br>
- in DC1, two clusters, say CL1 and CL2<br>
- In CL1, one host, say H1. And in CL2 one host, say H2<br>
- iSCSI Data Storage domain is configured where external
storage LUNs are exported to host H1(A host in CL1 of Datacenter).
<br>
</blockquote>
<br>
While adding H1 to CL1 is succeeded; addition of H2 in CL2 is
failing with following error in vdsm.log.<br>
