Change Host on Master Data Storage

Hello All,

Deployed one RHEV-H 7.2 and added it to RHEV-M 3.6 on RHEL 6.7 with iSCSI storage from ISCSI target hosted on RHEL 7.2.

I had to restart iSCSI target server - post restart "Use Host" on "Data (Master)" storage domain became empty and unable to update because "Use Host" is disabled on "Edit Domain".

Can anyone let me know how to edit master data storage and update the host without deleting datacenter and creating it.

Uploaded picture of Edit Domain for reference.,

Thanks /Praveen
