Replacement of a disk array controller board
!
Use the configuration utility to restore the disk array configuration
information in the disk array controller boards. For details, refer to the
online documentation on the NEC EXPRESSBUILDER CD-ROM that
comes with your system or the vendor documentation that comes with the
disk array controller. If a disk array controller is replaced, use the proper
utility to create new configuration information.
When more than one disk array controller board is installed in your
!
system, install the disk array controller board in the PCI slot with the
highest boot priority (system disk boot slot). See Table 4-2.
For example, if four disk array controller boards are installed in PCI slots
2 through 5, the system disk should be connected to the board installed in
PCI slot 3.
