Chapter 2. Installation
In Red Hat Enterprise Linux 6.2, the compression format used for the initrd.img
file has changed. The image is now compressed using LZMA rather than Gzip.
xz -d
command. For example:
~]# xz -dc initrd.img | cpio -id
xz -9 --format=lzma
command. For example:
~]# find . | cpio -c -o | xz -9 --format=lzma > initrd.img
Fibre Channel and Serial Attached SCSI (SAS) devices can be now specified by a World Wide Name (WWN) or a World Wide Identifier (WWID) for unattended installations. WWN is part of the IEEE standard which makes it easier to identify storage devices during installation for users utilizing Storage Area Networks (SAN) and other advanced network topologies. When a storage device is attached to a server using multiple physical paths for redundancy or improved performance, WWN for any of these paths is sufficient to identify the device.
The initial RAM disk file on 64-bit PowerPC and 64-bit IBM POWER Series systems is now named initrd.img
. In previous releases, it was named ramdisk.image.gz
.
In Red Hat Enterprise Linux 6.2, a static IPv6 address can be specified for the ipv6
boot option for network installations. The specified address must be of the following form:
<IPv6 address>[/<prefix length>]
3ffe:ffff:0:1::1/128
. If the prefix is omitted, the value of 64
is assumed. Specifying a static IPv6 address for the ipv6
boot option complements the already existing dhcp
and auto
parameters that can be specified for the ipv6
boot option.
