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 Web9.

 

 

 

Important: Fastwrite must not be enabled on the boot

 

resource SSA adapter.

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
