available to the specific partition, using
mksysb
, for
example.
SCSI disk, and Virtual SCSI disk The more common method of booting the system is to
use a disk situated in one of the hot-swap bays in the
front of the machine. However, any external
SCSI-attached disk could be used if required. As
described in previous sections, Virtual SCSI devices are
also available to a logical partition.
SSA disk
The p5-570 supports booting from an SSA disk either as
an AIX system disk or as a RAID LUN. For more
information about the SSA boot, see the SSA Frequently
Asked Questions located on the Web

.
SAN boot
It is possible to boot the p5-570 system from an SAN
using a 2 GB Fibre Channel Adapter (FC 6239 or
FC 5716), or to boot one partition using the dedicated
2 GB Fibre Channel Adapter or the Virtual SCSI device
related to this adapter. The IBM 2105 Enterprise Storage
Server (ESS) is an example of an SAN-attached device
that can provide a boot medium.
LAN boot
Network boot and NIM installs can be used if required.
Logical partitions can use either a dedicated Ethernet
adapter or Virtual Ethernet to accomplish this.
2.11.10 Security
The p5-570 system enables you to set two different types of passwords to limit access to
these systems:
The
admin
password is usually used by the system administrator, and the
general ID password
provides limited access to the system functions and is usually available
to all users who are allowed to power-on the server, especially remotely. These are defined in
the ASMI menus.
2.12 Operating system requirements
All new POWER5 servers are capable of running IBM AIX 5L for POWER and support
appropriate versions of Linux. AIX 5L has been specifically developed and enhanced to
exploit and support the extensive RAS features on IBM
Sserver
pSeries systems.
2.12.1 AIX 5L
The p5-570 requires AIX 5L Version 5.3 or AIX 5L Version 5.2 Maintenance Package
5200-04 (IY56722) or later.
The system requires the following media:
AIX 5L for POWER Version 5.2 5765-E62, dated 08/2004 (CD# LCD4-1133-04) or later
AIX 5L for POWER Version 5.3 5765-G03, dated 08/2004 (CD# LCD4-7463-00) or later
Important: Fastwrite must not be enabled on the boot
resource SSA adapter.
