HP 3PAR AIX and IBM Virtual I/O Server Implementation Guide

8 Booting from the HP 3PAR StoreServ Storage
For details about connecting the HP 3PAR StoreServ Storage to the host, see “Configuring the HP
3PAR StoreServ Storage for Fibre Channel” (page 7).
Setting the Host HBA Parameters for a SAN Boot
The IBM FC HBA does not require setting parameters on the host side to support booting from the
HP 3PAR StoreServ Storage.
Assigning LUNs as Boot Volumes
On the HP 3PAR StoreServ Storage, create a VV of appropriate size and export a VLUN to the
host definition that will be used to represent the AIX or IBM Virtual I/O Server for booting from an
HP 3PAR StoreServ Storage.
For details, see “Configuring the HP 3PAR StoreServ Storage Running HP 3PAR OS 3.1.x or OS
2.3.x” (page 7) and “Exporting LUNs to the AIX or IBM Virtual I/O Server Host” (page 29).
For the purpose of the AIX or IBM Virtual I/O Server installation, restrict the connection from the
host to the HP 3PAR StoreServ Storage to a single path. Only a single path should be available
on the HP 3PAR StoreServ Storage and a single path on the host to the VLUN VV that will be the
AIX or IBM Virtual I/O Server boot volume.
Installing the AIX or IBM Virtual I/O Server Host OS for a SAN Boot
Installation of the AIX 7.1, AIX 6.1, AIX 5.3, or IBM Virtual I/O Server operating system is supported
when it is booted from the HP 3PAR StoreServ Storage. Before installing AIX or the IBM Virtual I/
O Server operating system on a HP 3PAR StoreServ Storage VLUN VV, you must remove or reduce
paths to a single path to the HP 3PAR StoreServ Storage VLUN VV. After installing AIX or the IBM
Virtual I/O Server, install the HP 3PAR ODM 3.1 or HP 3PAR MPIO 2.2 for AIX and then reboot
the AIX or Virtual I/O server. With the HP 3PAR ODM 3.1 or HP 3PAR MPIO 2.2 installed, multiple
paths to the boot volume are supported and can then be configured. Follow all recommended
settings and guides as covered in this document.
NOTE: During the installation phase, restrict the number of paths to the HP 3PAR StoreServ
Storage AIX or IBM Virtual I/O Server boot volume to a maximum of one.
NOTE: Once HP 3PAR ODM 3.1 or HP 3PAR MPIO 2.2 for AIX or IBM Virtual I/O Server has
been installed, it can not be de-installed for a host boot disk.
AIX or IBM Virtual I/O Server host boot is supported by the HP 3PAR StoreServ Storage. To install
the AIX or IBM Virtual I/O Server operating system on HP 3PAR StoreServ Storage volumes,
complete the following steps:
1. Configure the HP 3PAR StoreServ Storage for the AIX system. See “Configuring the HP 3PAR
StoreServ Storage Running HP 3PAR OS 3.1.x or OS 2.3.x” (page 7) and “Exporting VLUNs
to the AIX or IBM Virtual I/O Server Host” (page 29).
2. For AIX, perform the following tasks:
a. Enter the SMS Menu and choose the options to boot from the CD-ROM.
b. Follow the standard procedure as outlined by IBM for installing AIX on a bootable device.
For details, see IBM AIX documentation.
c. At the end of the installation options, prior to the OS install, change the installation settings
by selecting the HP 3PAR StoreServ Storage volume. Deselect any other installation
devices.
d. Install the AIX operating system on the selected HP 3PAR StoreServ Storage volume.
3. For the IBM Virtual I/O Server, perform the following tasks:
