3.2Fibre Channel Card Notes

When a Fibre Channel card is installed in the server after installation of the OS, it should be auto- matically recognized the next time the OS is restarted. Proceed as follows:

Red Hat Enterprise Linux

The kudzu starts automatically during the system reboot. Select "Ignore".

SUSE Linux Enterprise Server

The "New hardware detection" window appears during the system reboot. Select "No".

3.3Fibre Channel Switch Notes

When using a Fibre Channel switch (ETERNUS SN200 series, Brocade DCX series) between the server and ETERNUS DX Disk storage systems, it is necessary to prepare and set the Fibre Channel switch in advance. When using a Fibre Channel switch (ETERNUS SN200 series, Brocade DCX series), be sure to read the "ETERNUS DX Disk storage systems Server Connection Guide (Fibre Channel) 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.

3.4Server 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 con- nected server, make sure that the ETERNUS DX Disk storage system does not shut down before the connected servers. Similarly, the Fibre Channel switches must also be turned off after the connected servers have been shut down.

If turned off, data writes from the running server cannot be saved to the ETERNUS DX Disk stor- age systems, and already saved data may also be affected.
