Working with boot disk partitions • Before creating a boot disk, you must start with a clean, unpartitioned virtual disk. • Create a LUN that is at least 32 GB for W2K3 and 46 Gb for W2K8. • When booting from a RAID array that has other virtual disks attached to other servers, be aware that when setting up booting for the new server, the installation program may display a list of partitions visible for loading the operating system. The display contains a disk for every controller port accessible by the HBA. • HP recommends that only one instance of the boot LUN be visible to the server during the initial installation. The installation may fail if multiple instances of the boot LUN are available to the server. Switch-based zoning You must be familiar with switch-based zoning. For specific information about zoning for your environment, see your switch's installation guide. Cabling options for single-channel HBAs SAN boot is supported in the zoned single-channel HBA configurations, as shown in Figure 1 through Figure 6. Figure 1 Single server, two single-channel HBAs, one switch, straight-cable storage configuration . 16 Boot from SAN

that when setting up booting for the new server, the installation program may display a list of
partitions visible for loading the operating system. The display contains a disk for every controller
port accessible by the HBA.

HP recommends that only one instance of the boot LUN be visible to the server during the initial
installation. The installation may fail if multiple instances of the boot LUN are available to the
server.
