Hi,
I have 3 Windows Servers 2012 R2 in a test lab: 172.16.0.64, 172.16.0.65 and 172.16.0.105.
The configuration I need to implement is provided on the Figure: _http://social.technet.microsoft.com/Forums/getfile/333051
The figure description:
Thick black lines – cables (physical connections).
Dashed lines – logical connections (iSCSI Initiator connections), in particular:
Red dashed lines show the connection of the first initiator to the local iSCSI target and to targets on two other servers.
Green dashed lines show the connection of the second initiator to the local iSCSI target and to targets on two other servers.
Blue dashed lines show the connection of the third initiator to the local iSCSI target and to targets on two other servers.
So, this configuration includes three clustered servers that constitute continuously available storage based on clustered storage pool of 3 MS iSCSI LUNs configured as mirrored storage spaces.
To build this configuration I installed iSCSI Target Server and Failover Clustering on all servers.
Thereafter, I launched File and Storage Services and went to the iSCSI section to create one iSCSI Virtual Disk for each server. Then, I added to the Access Server list allowed IP addresses for each server. _http://social.technet.microsoft.com/Forums/getfile/333062
I launched MS iSCSI Initiator on each of these three servers and add their IP addresses (172.16.0.64, 172.16.0.65 and 172.16.0.105) on the Discover Portals tab. Then, I connected three offered targets.
In the Failover Cluster Manager I created a cluster based on these servers.
I planned to add these newly created and connected server disks to a cluster storage pool, and then create a number of Clustered Storage Spaces. However, while creating a cluster, all previously connected targets in iSCSI Initiator disconnected and got the Reconnecting status. After that disks were not available.
Would you please suggest me the right way of creating Clustered Storage Space out of iSCSI Virtual Disks based on the local servers? Am I doing anything wrong?
Note that if iSCSI Virtual Disks are created on separated servers, there is no such a problem. In this particular case targetskeep connections during creation of the cluster. As a result the cluster is created successfully, disks can be added to a cluster storage pool, and Clustered Storage Spaces are created correctly and without any complexities.
