If the server has an optional RAID adapter and you have installed or removed a hard disk drive, see the documentation that comes with the RAID adapter for information about reconfiguring the disk arrays. If the server has a RAID configuration using the SCSI controller with integrated RAID and you have installed or removed a hard disk drive, you might have to reconfigure the disk arrays. See the RAID documentation on the IBM ServeRAID-7e (Adaptec HostRAID) Support CD for more information about reconfiguring the disk arrays. For information about configuring the integrated Gigabit Ethernet controllers, see the User's Guide. Connecting external options If you install a SCSI adapter or use the external SCSI connector, you can attach external SCSI devices, such as a SCSI storage expansion enclosure, to the server. You can attach additional external options to the other input/output (I/O) connectors on the front and rear of the server. (See "Input/output connectors" on page 55 for more information.) Complete the following steps to attach an external device: 1. Read the "Installation guidelines" on page 23.and the safety information beginning on page Appendix B, "Safety information," on page 117. Also, read the documentation that comes with the option. 2. Turn off the server and all attached devices (see "Turning off the server" on page 7). 3. Follow the instructions that come with the option to prepare it for installation and to connect it to the server. Note: If you are attaching an external SCSI device, see "Ultra320 SCSI controller system-board connectors" on page 56 for information about SCSI cabling and SCSI IDs.
