no. you can access a storage domain from multiple clusters in same DC.
[Santosh]
That is my understanding also.
which type of storage?
[Santosh] 'Storage' is of
'iSCSI' type. Domain type is 'Data (Master)'
could it be its "protecting" shared access to the DC?
[Santosh] How should I find it out?
is moving the host to same cluster as the SPM resolving the issue
for
you (it shouldn't)
[Santosh] Moving the host to the same cluster as that of SPM
did not
resolve the issue.
Thanks for the reply.
Regards, Santosh.

<pre wrap="">Hi,

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