Configuring Disk Drives, Disk Arrays, and CD-ROM Drives
Moving a Disk Drive to a Different Address
Step 13. If you are moving a disk containing the root file system, you must change
the hardware path that is read from stable storage:
a. Start up your system, but override the autoboot. Do not boot from the
primary or alternate boot path. Instead, enter Boot Administration
mode.(Note, boot ROM administration is system-dependent, and thus
differs for Series 700 and 800 systems. The boot ROM menus,
however, are self-explanatory. Use one of the help commands (Help or
?) whenever you are uncertain of what to do.
b. On a Series 700, boot from the new hardware address of your root
disk by using the Boot command and proceed to the initial system
loader. For example,
BOOT-ADMIN> boot 2/0/1.4.0 is
On a Series 800, enter the new hardware address of your root disk
and boot your system. For example, if your new hardware address is
52.1, enter b 52.1.
Answer Y to the prompt: Interact with IPL? This will invoke the
initial program loader.
c. Set the system's primary boot path in stable storage to the new
hardware address, by using the primpath command at the ISL>
prompt. The system will prompt you to enter the primary boot path.
d. Verify the contents of your AUTO file, this time, by executing the
lsautofl command. You should see hpux (;0)/stand/vmunix.
e. Boot your system by typing in the contents of the AUTO file. Note, if
you have moved a root LVM disk, boot to LVM maintenance mode by
using the -lm option.
For example,
ISL> hpux boot (;0)/stand/vmunix
or
ISL> hpux -lm boot (;0)/stand/vmunix
This command loads the kernel from the HP-UX file system and
transfers control to the loaded device. On booting up, insf identifies
all devices it finds (including the newly moved disk) and creates /dev
files for them.
Step 14. Log in.
Step 15. If you have moved an LVM root disk, proceed through the following
sequence of commands to gain access to the root disk at the new location:
