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.
