my server system is low on disk. To install a new kernel I think i shall do the following:
1. compile the kernel on another system.
2. copy bzImage along with config, System.map and of course the laodable module in /lib/modules and transfer them to the server.
3. Now, I can remove the server's old kernel to free up the space and put the the files in /boot as well as copying loadable modules to
no,... this is not the way, this way I need to make the drivers the image as well. There's another way, in ubuntu I can make .deb files of the headers and the linux, if I transfer only those two files to the server, I think i can install the new kernel using dpkg. what do you think?
We use netboot to boot our RedHat Linux kernels. We usually use mknbi tool to create netboot image from Red Hat Linux kernel. However, I can't get this to work with the new Red Hat EL6 kernel.
One online document I found seems to say mknbi should not be used for Linux 2.6 or newer kernels any... (1 Reply)
Hi gurus
Could anybody tell me which file is read by kernel to set its default system kernal parameters values in solaris. Here I am not taking about /etc/system file which is used to load kernal modules or to change any default system kernal parameter value
Is it /dev/kmem file or something... (1 Reply)
Hello friends,

prestosetup(8) System Manager's Manual prestosetup(8)NAME
prestosetup - Configures the Prestoserve software
SYNOPSIS
/usr/sbin/prestosetup
DESCRIPTION
The prestosetup command is an interactive facility that allows you to set up Prestoserve on your system. Prestoserve speeds up synchronous
disk writes, including NFS server access, by reducing the amount of disk I/O. The prestosetup command also allows you to modify the
Prestoserve configuration on your system.
In order to use Prestoserve, your system must contain the necessary Prestoserve hardware.
The prestosetup command verifies that the Prestoserve license is registered, the Prestoserve utilities are installed, and the Prestoserve
software is configured into your kernel. Note that some Prestoserve hardware configurations require different forms of kernel configura-
tion. If the Prestoserve hardware was installed in your system when the operating system was installed, the Prestoserve software will be
automatically configured into your kernel. If not, you may have to rebuild your kernel to include the correct Prestoserve controller
device before you run prestosetup.
The prestosetup command configures Prestoserve on your system by asking the following questions: Do you want Prestoserve automatically
enabled at system startup? Which file systems do you want to accelerate? To specify a file system, use the mount point. Do not specify a
block device because some functional subsystems, such as the Advanced File System (AdvFS), can map more than one block device to a mount
point. Do you want to start Prestoserve now?
After you have entered the necessary information, the prestosetup command displays the information that you entered and prompts you to con-
firm that the information is correct. If the information is not correct, the prestosetup command exits and no changes are made. If the
information is correct, the prestosetup command does the following: Creates the /dev/pr0 Prestoserve control device if necessary. Creates
the /etc/prestotab file and includes the mount points for the file systems that you want automatically accelerated when the system starts
up. Updates the /etc/rc.config file and sets the appropriate run-time configuration variables. Updates the /sbin/init.d/presto startup
script with the Prestoserve configuration information from the /etc/rc.config file.
If you choose not to automatically enable Prestoserve when you start up the system, you must manually start the prestoctl_svc daemon and
use the presto command to accelerate the file systems.
The prestosetup command also allows you to modify the Prestoserve configuration on your system. For example, you may want to add addi-
tional file systems to the list in the /etc/prestotab file.
FILES
Lists the mount points for the file systems that you want automatically accelerated when the system starts up.
