    The Fibre Channel switches that can be connected depend on the connection configuration that is used (the OS and the ETERNUS AF/DX). Refer to the "Server Support Matrix for FC-SWITCH" before starting. When a Fibre Channel switch (ETERNUS SN200 series, Brocade series) is to be used between the server and ETERNUS AF/DX, follow the preparation-in-advance and Fibre Channel switch setup procedures given in the "Configuration Guide -Server Connection- (Fibre Channel) Fibre Channel Switch Settings".

    Example: # lvchange -r N /dev/vg01/lvol_name Execute this command for all logical volumes created on ETERNUS AF/DX storage systems' LUNs to disable [Bad Block Relocation]. If [Bad Block Relocation] is not disabled, file system may be damaged. Raw device access to an LVM logical volume must use an I/O block size that is a multiple of 1024bytes.

    "Ready". If the server is turned on and they are not "Ready", the server will not be able to recognize the ETERNUS AF/DX storage systems. Also, when the ETERNUS AF/DX power supply is being controlled by a connected server, make sure that the ETERNUS AF/DX 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.

    Check the World Wide Name (WWN). When using the "Security" function (Affinity Mode) of the ETERNUS AF/DX storage systems, it is necessary to specify the WWN of the Fibre Channel card. Use the "fcmsutil" command to specify the device file of the Fibre Channel card, and the WWN of the Fibre Channel card can be checked.
