Booting and Resetting nPartitions
Configuring Boot Paths and Boot Actions
HP System Partitions Guide: Administration for nPartitions, rev 5.1 232
Step 1. Determine which devices will be used for booting HP-UX on the
nPartition, and determine the boot behaviors you desire for the PRI boot
path.
Step 2. Login to HP-UX running on an nPartition in the complex.
You can modify the boot paths for any nPartition from any other
nPartition in the complex when using the parmodify command.
However, when using the setboot command to modify the PRI and ALT
paths or the PRI boot action, you can modify only the local nPartition’s
settings.
Step 3. Configure boot path settings using the parmodify -p # ... command.
Use the following commands to set the boot path variables for a specified
partition number (-p # ):
• PRI path—parmodify -p # -b PRI where PRI is the hardware path.
• HAA path—parmodify -p # -s HAA where HAA is the hardware
path.
• ALT path—parmodify -p # -t ALT where ALT is the hardware path.
If using the setboot command to set boot paths for the local nPartition,
you can specify setboot -p PRI or setboot -a ALT but cannot set the
HAA path variable.
You can list an nPartition’s current boot path settings by issuing the
parstatus -V -p # | grep Path command and specifying the partition
number (-p # ). The setboot command with no arguments lists the PRI
and ALT settings for the local nPartition as well as the local nPartition’s
PRI path flags (boot actions).
For example, to set the PRI boot path to 0/0/4/0/0.8.0 and the HAA boot
path to 0/0/4/0/0.9.0 for partition number 0, issue the parmodify -p0
-b 0/0/4/0/0.8.0 -s 0/0/4/0/0.9.0 command, as shown below.
# parmodify -p0 -b 0/0/4/0/0.8.0 -s 0/0/4/0/0.9.0
Command succeeded.
#
Step 4. As needed, configure the PRI boot action for the local nPartition by using
the setboot -b Autoboot -s Autosearch command.
