22. Click Continue, then click Exit.
A prompt asks, “Are you sure?”
23. Click Yes.
Continue by configuring the hosts file (7.1.3).
4.3. Configuring the RAID Controller
Configure the RAID disk controller for RAID level 1 (mirroring) for two disks units.
Sites can reconfigure a different RAID level following hardware RFU if desired. For
detailed information see the Mylex RAID Management documentation available on the CD-
ROM labeled "Mylex Solutions Software Kit x.xx."
Notes:
• Switch the monitor concentrator to the Intel node position before beginning (see
2.5.2).
• If you are performing a full installation on a system that was preloaded, do not
format the RAID disk. Instead, use the DAC BIOS utility to initialize the RAID
volume before you reload the operating system. Formatting the disk makes the drive
unrecognizable to the software.
• In step 2, you must press Alt-M within a few seconds to enter the BIO Options
Utility.
• In step 8, you must press Alt-R within a few seconds to enter the RAID controller
configuration procedure; otherwise, the normal boot procedure continues. See next
note for ES2024R server.
• For the ES2024R server, before you press Alt-R, you must press Alt-M to access the
BIOS options utility. Then press Alt-R in order to access the Mylex RAID EzAssist
utility, as instructed in step 8.
Take the following steps to run the RAID controller configuration utility:
1. Power on or reboot the Intel node.
Several start-up messages appear, including a prompt to press Alt-M, as follows:
