update /etc/fstab
Create logical volume or filesystem

swapon <device> | -f <logical device>
swapon -p 3 <device> | -f <logical device>

update /etc/fstab

Note: -p = priority swap number . The nswapdev tunable system parameter controls the maximum number of swap devices.
mkps -a -s 4 -n <volume group>

# change the attributes
chps -a n paging00 (don't use after restart)

# change the logical volume attributes (name in this case)
chlv -n <new name> <old old> (chang page space name)

Note:

-a reconfigure paging space after restart
-s size of the page space (logical partitions)
-n activiates the paging space (use swapoff to deactivate)

also see /etc/swapspaces file
adding swap

update /etc/vfstab
swap -d
swapoff <device>|<file>

Remove device or file as normal
swapoff <device>|<file>

Remove device or file as normal
remove entry from /etc/fstab

Note: Boot programs are stored in the boot area in Logical Interchange Format (LIF), which is similar to a file system. For a device to be bootable, the LIF volume on that device must contain at least the ISL
(the initial system loader) and HPUX (the HP-UX bootstrap utility) LIF files. ISL is like GRUB.

Disk disk partitions
List Raw Partitions
use format to partition the disk then just use the slice as a raw partition, remember to use the character device
## Old way

service rawdevices start
chkconfig rawdevices on
## New way, Edit below file
/etc/udev/rules.d/60-raw.rules
udevinfo -d or udevadm

## Display raw partitions
raw -qa
mknod /dev/rawctl c 162 0
mknod /dev/raw/raw0 c 162 1
mknod /dev/raw/raw1 c 162 2
ln -s /dev/rawctl /dev/raw/rawctl

## map raw devices to the disk
raw /dev/raw/raw1 /dev/sdb1

## display raw devices
raw -qa
Just create a new LVOL without a filesystem - that's it.

boot prompt commands
Boot process
Phases:
  • Boot PROM: displays system information, run POST, load bootblk, locate ufsboot
  • Boot Programs: bootblk loads and executes the ufsboot
  • Kernel Initialization: ufsboot loads and executes the core kernel, initializes core kernel data structures, loads other kernel modules based on the /etc/system file, starts /sbin/init program
  • init: starts other processes based on the /etc/inittab file
Boot sequence
  1. BIOS
  2. POST
  3. Master Boot Record (MBR) - point to the bootloader GRUB or LILO
  4. GRUB (stage 1) - point to GRUB stage 1_5
  5. GRUB (stage 1_5) - deals with specific filesystem types look at /boot/grub/*1_5 files
  6. GRUB (stage 2) – reads /etc/grub.conf and displays the grub menu, it specifies the kernel and the initrd files
  7. KERNEL - control given to the kernel
  8. INIT - reads /etc/inittab and runs /etc/rc.d/rc.sysinit script

  4. GRUB (stage 1) - point to GRUB stage 1_5
  5. GRUB (stage 1_5) - deals with specific filesystem types look at /boot/grub/*1_5 files
  6. GRUB (stage 2) – reads /boot/grub/menu.lst and displays the grub menu, it specifies the kernel and the initrd files
  7. KERNEL - control given to the kernel
  8. INIT - runs the /etc/event.d/rc-default script
Phases:
  1. PDC - processor-dependent code; executes and performs self-tests
  2. ISL - initial system loader; loads the secondary system loader hpux
  3. HPUX - is the secondary system loader and loads the kernel /stand/vmunix, then hands over to the kernel
  4. KERNEL - swapper processes are started by the kernel then starts the init process
  5. INIT - reads /etc/inittab
Phases:
  • Read Only Storage (ROS): check the system board, perform POST, locate and load boot image, begin system initialization and execute phase 1 of the /etc/rc.boot script
  • Base Device Configuration: start configuration manager to configue base devices
  • System Boot: start init process phase 2, switch to hard-disk root filesystem, start other processes defined by /etc/inittab and execute phase 3 of the /etc/rc.boot script
