HP-UX Virtual Partitions Administrator's Guide (includes A.03.05 and A.04.05)

5. Import the root volume group (vg00). For example:
vgimport -m /mapfile.vg00 /dev/vg00 /dev/dsk/c1t1d0 /dev/dsk/c1t1d1
where the device filenames are obtained from the ioscan and vgscan above
6. Activate the root volume group (vg00):
vgchange -a y /dev/vg00
You may also have to cleanup and prepare LVM logical volume to be root, boot, primary
swap, or dump volume as follows:
lvrmboot -r /dev/vg00
lvlnboot -b /dev/vg00/lvol1
lvlnboot -r /dev/vg00/lvol3
lvlnboot -s /dev/vg00/lvol2
lvlnboot -d /dev/vg00/lvol2
mount
7. Verify that the hardware path for the boot device matches the primary boot path.
lvlnboot -v /dev/vg00
8. If the hardware path has not changed to the primary boot path, change it by running
lvlnboot with the recovery (-R) option. This step is normally not necessary.
lvlnboot -R /dev/vg00
9. Reboot the target virtual partition.
Resetting a Virtual Partition
Just as it is occasionally necessary to issue a hard reset (RS) or a soft reset (TOC) for a non-vPars
OS instance, it is occasionally necessary to issue similar resets for a vPars OS instance.
Hard Reset
On hard partition not running vPars, a hard reset cold boots the hard partition. To issue a hard
reset, the administrator types a CTRL-B at the console to connect to the service processor and
then types the command RS (reset), at which time the hard partition cold boots.
On a hard partition running vPars, a hard reset will reset the hard partition--including the Monitor
and all the virtual partitions.
To simulate a hard reset on only a virtual partition, from a running virtual partition, use
vparreset with the -h option. For example, if winona2 is hung, we can execute vparreset
from the running partition winona1:
winona1# vparreset -p winona2 -h
The -h option also inhibits the autoboot behavior (just like shutdown -h does); therefore -h can
be used to break out of a reboot loop. Because -h overrides the autoboot setting for that virtual
partition, the partition must be manually restarted via vparboot (e.g., winona1# vparboot
-p winona2).
Other virtual partitions are unaffected when one virtual partition is reset.
Soft Reset
On a hard partition not running vPars, a soft reset (TOC) allows HP-UX to attempt to capture a
state and potentially create a crash dump and then the hard partition reboots. To issue a soft
reset, the administrator types a CTRL-B at the console to connect to a service processor and then
types the command TC (transfer of control).
On a hard partition running vPars, a soft reset will take dumps of all the virtual partitions
2
as
well as the Monitor image, and then the hard partition reboots.
