Boot arguments may include more than one string. All argument strings are passed to the secondary boot program; they are not interpreted by OpenBoot. If any arguments are specified on the boot command line, then neither the boot-file nor the diag-file nvram variable is used. The...
1. Invoking grub2-install The program ‘grub2-install’ generates a GRUB core image using‘grub2-mkimage’ and installs it on your system. You must specify the device name on which you want to install GRUB, like this:
Grub Security Authentication and authorization in GRUB By default, the boot loader interface is accessible to anyone with physical access to the console: anyone can select and edit any menu entry, and anyone can get direct access to a GRUB shell prompt. For most systems, this...
Booting GRUB from the network The following instructions don’t work for *-emu, i386-qemu,i386-coreboot, i386-multiboot,mips_loongson, mips-arc and mips_qemu_mips to generate a netbootable directory, run: grub2-mknetdir –net-directory=/srv/tftp –subdir=/boot/grub -d /usr/lib/grub/<platform> E.g. for i386-pc: grub2-mknetdir –net-directory=/srv/tftp –subdir=/boot/grub -d /usr/lib/grub/i386-pc Then follow instructions printed out by grub2-mknetdir on...
1. Grub Configurations GRUB is configured using ‘grub.cfg’, usually located under ‘/boot/grub’. This file is quite flexible, but most users will not need to write the whole thing by hand. 1.1 Simple configuration handling The program ‘grub2-mkconfig’ generates ‘grub.cfg’ upgrading a distribution, and will discover available...
1. Introduction to Grub Briefly, a “boot loader” is the first software program that runs when a computer starts. It is responsible for loading and transferring control to an operating system “kernel” software (such as Linux or GNU Mach). The kernel, in turn, initializes the rest...

Why we need install Apache2 under SMF manually, isn’t that configured automatically when we install the package ? Actually, If the Apache 2 ( httpd) server is installed along with the Solaris 10 installation, the SMF entries for Apache 2 are configured by default. However, if...
During regular maintenance It is often a requirement to us to determine which disk we actually boot from when the root volume is under volume manager control. Solaris on SPARC Sparc with SVM # prtconf -pv|grep bootpath: bootpath: ‘/sbus@3,0/SUNW,fas@3,8800000/sd@1,0:a’ Sparc with VxVM Root Volume...
I came across one unique parameter which I would like to share on our gurkulindia, specially for small business organisations where we dont have seperate power backups for DC. Has anyone noticed while working on Solaris boxes if you will power down (init 5 or poweroff...
