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.

2.3 Server Notes
Before turning the server on, check that the ETERNUS DX/AF storage systems and Fibre Channel switches are
all "Ready". If the server is turned on and they are not "Ready", the server will not be able to recognize the
ETERNUS DX/AF storage systems.
Storage replication functions (local and remote) are performed by SHC-OSD (subsystem of BS2000) instead of
ETERNUS SF AdvancedCopy Manager.
SE Server (SU /390) and S-Server:
Before an online firmware update in the ETERNUS DX/AF storage system is performed, the timeout value for
the affected disks in the BS2000 must be increased to 2.5 minutes using the command /MODIFY-IO-UNIT. After
completion of the update, the standard timeout (1 minute) must be reset via /MODIFY-IO-UNIT.
For online firmware upgrades in 'operator intervention mode', additional conditions apply. Please respect
'important notices' and 'restrictions' in the storage bulletins.

Chapter 4
Set Up the ETERNUS DX/AF Storage System
for BS2000
This section explains the required special settings for BS2000. For details of how to use
ETERNUSmgr to perform these settings, refer to the "ETERNUSmgr User Guide".
4.1 Setting the Host Responses
The ETERNUS DX/AF storage system Host Response parameters must be set to match the way in which the
server will process the ETERNUS DX/AF storage system request responses.
These parameters are different for each OS, they must be set before connecting the ETERNUS DX/AF storage
system to the server.
Using the predefined "Host Response Profile" with the name "BS2000" is recommended.
The standard BS2000 Host Response "BS2000" is preset with the correct parameter settings (incl. 4096
volumes / port).
When setting the access path using the ETERNUS SF Storage Cruiser, Host Response No. will be set to default
values.
Set the Host Response No. after setting the access path using the ETERNUS SF Storage Cruiser.

Parameter BS2000
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 combine Port Mode CA/RA is not supported by ETERNUS DX S2, but
tolerated as of ETERNUS DX S4/S3 and ETERNUS AF.
Note: In these terms the Management Unit (MU) and the Server Unit (SU x86) of an SE Server, resp. the
Server Unit of an SQ-Server are considered to be a BS2000 server, irrespective of whether Linux/Windows
guests are running or not on the Server Unit. The Application Unit of an SE Server /SQ-Server is a non-BS2000
server.
When setting a Fabric connection, complete the preparation work and set up the Fibre Channel switch
beforehand.

17
4.3 Registering the WWNs of the Accessing Fibre Channel Cards
Register the WWN of each Fibre Channel card installed on the server that will access the ETERNUS DX/AF
storage system. At the same time, set the host response numbers registered in "4.1 Setting the Host
Responses" (page 14) to accept these WWNs.
WWN registration combined with the host affinity settings (described later) limits which server has access to
which ETERNUS DX/AF storage system LUNs.
SE Server (SU /390) and S-Server:
We recommend assigning a name which identifies the host and the FC channel (e.g. FC channel 8C on the
host S210 -> Name "S210-8C").
SE Server (SU x86) and SQ-Server:
We recommend assigning a name which identifies the host and the slot and port number of the FC channel
(e.g. FC channel in slot 2 port 0 on the host host1 -> Name "host1-2-0").
When a server-side Fibre Channel is replaced (SQ-Server or SE Server (SU x86)), the WWN of the replacement
Fibre Channel card must be re-registered to the ETERNUS DX/AF storage system.

18
4.4 Configure the RAID Groups and Create the Logical Volumes
Configure a RAID Group
With the (default) setting "Controlling CM = Auto" ETERNUSmgr automatically assigns the RAID group to a
Control Module (CM) and a CPU in the CM. The assignment can also be made directly by specifying a CM# and
a CPU#.
As FC ports are also assigned to a CM and a CPU, direct assignment can also lead to better performance results
under certain circumstances.
Create the Logical Volume on a RAID Group
A maximum of 128 Volumes can be created per RAID Group
BS2000 supports a maximum of 2**32 - 1 blocks of 512 bytes per logical volume. Logical volumes of 2TB or
larger are thus not completely utilized by BS2000. Only use values of up to 2048 x 1024 = 2,097,152 in
"Capacity".
The recommended capacity of the logical volumes for BS2000 should be between 25 GB and 100 GB.
The maximum supported LUN capacity is 2TB.

Copyright 2018 FUJITSU LIMITED P3AM-5672-10ENZ0
19
4.5 Creating the LUN Groups/Affinity Groups
Set the LUN groups which will be accessible by the BS2000 server.
ETERNUS DX/AF storage system:
A maximum of 4096 LUNs per FC port of the storage system is supported for connections to the BS2000 server
depending on the server model.
Please be aware that if the storage system is configured for 4096 LUNs per FC port, the number of host FC
ports per CA port is limited to 32.
SE Server (SU /390):
A maximum of 4096 volumes can be configured in an affinity group, i.e. for a connection from one FC channel
to one FC port in the RAID system. However, we recommend assigning significantly fewer volumes to an
affinity / LUN group so that PAV alias devices can also be generated on the same channel path.
S-Server:
A maximum of 256 volumes can be configured in an affinity group as a maximum of 256 volumes is
supported per channel path, i.e. for a connection from one FC channel to one FC port in the RAID system.
However, we recommend assigning significantly fewer volumes to an affinity / LUN group so that PAV alias
devices can also be generated on the same channel path.
SE Server (SU x86) and SQ-Server:
A maximum of 1024 DX/AF volumes is supported per affinity / LUN group and HBA port (server). No free
volumes in the affinity group are required for PAV alias devices.
4.6 Configuring the Host Affinity
Allocate the WWN of each server to an affinity and specify the accessible LUNs. This sets the access restrictions
for each server connected to the ETERNUS DX/AF storage system.
Controller Category Action
DX/AF series Connectivity > LUN Group Add LUN Group
To recognize a LUN which has the same configuration for multiple Fibre Channel cards, such as in multipath
and cluster configurations, add settings to assign these Fibre Channel cards to the same Host Affinity.

4.7 Setting the CA Reset Groups
All FC ports (CAs) assigned to one affinity group or referring the same LUN group must be assigned to the
same reset group.
When multiple BS2000 servers share LUNs on an ETERNUS DX/AF storage system, any disk storage system CA
port that connects a shared LUN to a BS2000 server must be assigned to the same reset group, whether
multipath connections are used for the BS2000 servers or not.
If other servers than BS2000 are connected to the ETERNUS DX/AF storage system, dedicated ports for the
BS2000 servers are necessary due to different CA parameter settings (see "4.2 Configuring Settings for the
Fibre Channel Ports (CA Parameters)" (page 15)):
"Reset Scope: T_L" and "Reserve Cancel at Chip Reset: On" are necessary for BS2000 server connections, but
different default values are mandatory for non-BS2000 server connections.
4.8 Checking the WWNs
Use ETERNUSmgr to check the WWN of each ETERNUS DX/AF storage system CA port.
They are required to connect the ETERNUS DX/AF storage system to the server.
