Fibre Channel Card Notes
When a Fibre Channel card is installed in the server after installation of the OS, it should be automatically
recognized the next time the OS is restarted. Proceed as follows when a response is requested:
For Red Hat Enterprise Linux
•
The kudzu starts automatically during the system reboot. Select "Ignore".
For SUSE Linux Enterprise Server
•
The "New hardware detection" window appears during the system reboot. Select "No".
For RHEL6.3 or Oracle Linux 6.3 with a QLogic Fibre Channel card
•
If the Fibre Channel connection is lost, "LOOP DOWN" may not be recorded on the log in the host.

Fibre Channel Switch Notes
When a Fibre Channel switch (ETERNUS SN200 series, Brocade DCX series) is to be used between the server
•
and ETERNUS DX Disk storage system, follow the preparation-in-advance and Fibre Channel switch setup
procedures given in the "ETERNUS DX Disk storage systems User's Guide -Server Connection- (Fibre Chan-
nel) Fibre Channel Switch Settings".
•
When 4Gbit/s QLogic Fibre Channel cards are connected to the ETERNUS SN200 series or Brocade DCX series
via Fibre Channel switch, and the SFP produces an incorrect linkup, change the Fibre Channel card BIOS
settings. Contact your maintenance engineer for SFP details.

Server Startup and Power Supply Control Notes
Before turning the server on, check that the ETERNUS DX Disk 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 Disk storage systems.
Also, when the ETERNUS DX Disk storage system power supply is being controlled by a connected server,
make sure that the ETERNUS DX Disk storage system or the Fibre Channel switches does not shut down be-
fore the connected servers. If turned off, data writes from the running server cannot be saved to the ETERNUS
DX Disk storage systems, and already saved data may also be affected.
3.7
System Design Sheet Notes
The system design sheet is a spreadsheet program work sheet that is used to simplify the process of instal-
ling the ETERNUS DX Disk storage system. It is important that the system details be recorded after first instal-
ling the system and also each time the system is subsequently modified, expanded, or has maintenance
work performed on it. Creating a system design sheet makes installation and maintenance of the system
easy.
