Chapter 256
Configuring LUN 0
For a disk array that is in a multi-host environment, the SCSI standard
requires a LUN 0 in certain scenarios:
• If the disk array is connected to the A6829A adapter, and you plan to
boot from that array, the disk array must be configured as LUN 0. Do
not configure the LUN with any LUN security (that is, do not restrict
access).
• If the disk array is connected to an A6829A adapter installed in an
HP-UX system that is running from a separate boot disk, the disk
array must be configured with LUN 0; otherwise, the ioscan
command will not detect all of the LUNs present in the disk array.
Once you have determined that LUN 0—if it is required—is configured
correctly, go to the section, “Verifying Installation” on page 58.
