Slice requirements for upgrading
|
When using the Solaris 8 Installation CD
and the Solaris Web Start program to upgrade, you must have a slice on the disk that
does not store files. The swap slice is preferred, but
you can use any slice that is not located in any of the “upgradable”
root slices that are listed in /etc/vfstab. The size
of this slice must be at least 512 Mbytes.

IA: fdisk partition requirements
|
When using the Solaris 8 Installation CD,
the Solaris Web Start program requires two fdisk partitions
on the system disk to perform an installation or upgrade.
-
Solaris fdisk partition
This is the typical Solaris fdisk partition. If
you do not have a Solaris fdisk partition on your system,
the Solaris Web Start program prompts you to create one.
Caution – If you change the size of an existing fdisk
partition, all data on that partition is automatically deleted. Back up your
data before you create a Solaris fdisk partition.
-
x86 boot fdisk partition
This is a 10 Mbyte fdisk partition that enables
the Intel architecture to boot the miniroot that is placed on the newly created
swap slice that is located on the Solaris fdisk partition.
Caution – Do not create the x86 boot partition manually.
The Solaris Web Start installation program creates the x86 boot partition,
removing 10–Mbytes from the Solaris fdisk partition.
By allowing the installation program to create the x86 boot partition, you
prevent any existing fdisk partitions from being altered.

IA system upgrade limitations
|
When you use the Solaris 8 Installation CD,
you cannot use the Solaris Web Start program to upgrade to Solaris 8 from
the Solaris 2.5.1, Solaris 2.6, or Solaris 7 operating environments. The Solaris 8 Installation
CD requires a separate 10 Mbyte IA boot partition that was not required in
previous Solaris releases. To upgrade, you must use the Solaris Web Start
program from the Solaris 8 DVD or a network installation image, or use the Solaris 8 Interactive Installation Program
or the custom JumpStart method.

IA systems logical block addressing Requirement
|
Do not use the Solaris 8 Installation CD unless your system can boot across
the 1024–cylinder limit. Logical block addressing (LBA) enables the
machine to boot beyond the 1024–cylinder limit and across Solaris disk
slices. Use the Solaris 8 Installation CD when your system's BIOS and SCSI
driver for the default boot disk supports LBA.
To determine if
your system supports LBA, type:
# prtconf -pv | grep -i lba
|
If the BIOS and SCSI driver for the default boot
disk support LBA, the following message appears.
If the SCSI driver for the default boot disk does not support
LBA, the following message appears.
If the default boot disk BIOS and SCSI driver do not support LBA, use the Solaris 8 DVD,
a net installation image, or another installation method to install or upgrade.
