Chapter 4 Set Up the ETERNUS DX/AF Storage System for BS2000

4.5 Creating the LUN Groups/Affinity Groups

4.5
Creating the LUN Groups/Affinity Groups
Set the LUN groups which will be accessible by the BS2000 server.
Controller
DX/AF series
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.
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.
