402 IBM Eserver i5 and iSeries System Handbook
RPQ 847184 Convert #64xx to #45xx/46xx
RPQ 837184 provides the mounting hardware to convert selected iSeries #64xx
features into the #45xx/#46xx equivalents for installation in iSeries servers or
expansion towers. System records should be updated via RPO to reflect removal
of the #64xx device from the prior server and installation of the #45xx/46xx
device on the iSeries.
Installation is not included in the price of this RPQ
Alternate IPL
Throughout this book and in the IBM Eserver iSeries and AS/400e System
Builder, SG24-2155, the term
alternate IPL (ALT-IPL) is used to describe both
alternate IPL devices and alternate installation devices. It is important to
understand the differences between the two concepts.
An alternate IPL device must be attached to an IOA adapter card that is
controlled by the base IOP in the system. Any other tape device can be an
alternate installation device.
Alternate installation device support allows you to perform installation and
recovery procedures using a combination of devices. Prior to V4R1, these types
of activities could only be performed using devices attached to the first system
bus. The first system bus connects to the service processor IOP. Typically this is
where the optical device or tape devices used for installations are attached. On
OS/400 V4 and later systems, you can use a combination of devices that are
attached on the first system bus and on additional buses. The alternate
installation device is not attached to the first system bus.
On the 520, 550, 570, 595, 800, 810, 825, 870, and 890 servers, the alternate
IPL device is attached to an I/O adapter that is controlled by a base IOP in the
system.
If you use the alternate installation function, the system uses existing support (a
device on the first system bus) to install or recover enough of the Licensed
Internal Code required to perform an IPL with an IPL-type D. When using the
alternate installation device support, the system continues the operation using
media in the alternate installation device. This function supports installation and
recovery from tape media, such as SAVSYS tapes or distribution tapes that you
Note: The #2765 PCI Fibre Channel Tape Controller does not support the
alternate IPL device function. A D-mode IPL is required using CD-ROM,
DVD-ROM, or another alternate IPL tape device. Then select a #2765 to
complete the installation or recovery process.
