Notes
2.1

Installation Notes

• To ensure reliable access to ETERNUS DX/AF storage systems, multipath configuration is recommended.
• Setting up multiple access paths between the BS2000 Server and the ETERNUS DX/AF storage systems
provides improved access redundancy.
• Before setting up a multipath configuration, create Storage Repositories for all the LUNs that exist in the
ETERNUS DX/AF storage system.
• The ETERNUS Multipath Driver does not need to be installed for BS2000 Servers.
2.2

ETERNUS DX/AF Storage System Setup Notes

• Host Response must be set before the ETERNUS DX/AF storage system is connected to the BS2000 Server
host.
• Assign Affinity Group values starting from LUN0 in ascending order. The server cannot recognize the
ETERNUS DX/AF storage system LUNs if some other assignment order is used.
• Please be aware that only a homogeneous sharing with other BS2000 Servers is supported for FC Ports
which are connected to a BS2000 server. The combined Port Mode CA/RA and port sharing with non-
BS2000 servers are not supported in ETERNUS DX S2.
The combined Port Mode CA/RA as of ETERNUS DX S4/S3, ETERNUS AF is tolerated.
Note: In these terms the Server Unit of an SE Server (SU x86) or an SQ-Server is considered to be a BS2000
server, irrespective whether Linux/Windows guests are running or not. The Application Unit of an SE Server
or an SQ-Server is a non-BS2000 server.
• The feature Transparent failover (TFO) / Storage Cluster Option is supported for BS2000 volumes as of OSD/
BC V10 and OSD/XC V10 with SHC-OSD V13.0.
