HP-UX Virtual Partitions Administrator Guide (includes A.05.08) (5900-1312, March 2011)

also set these values on a vPars server from the HP-UX shell of a virtual partition using the
vPars command vparutil. For more information, see the vparutil(1M) manpage.
For vPars A.04.xx and later: use the mptconfig command to view or set the SCSI parameters
for Ultra320 host bus adapters (HBAs). For information on the mptconfig command, see
the HP A7173A PCI-X Dual Channel Ultra320 SCSI Host Bus Adapter Support Guide. For
Ultra2/Ultra160 SCSI HBAs, the SCSI parameters can only be set from the BCH prompt (on
PA-RISC) or from the EFI Shell prompt using EFI applications (on Integrity). For information on
setting and confirming SCSI parameters for Ultra2/Ultra160 HBAs, see the HP A6828A PCI
Ultra160 SCSI Host Bus Adapter: Service and User Guide.
• System-wide stable storage and the setboot command
On a non-vPars server, the setboot command allows you to read from and write to the
system-wide stable storage of non-volatile memory. However, on a vPars server, the setboot
command does not affect stable storage. Instead, it only reads from and writes to the vPars
partition database.
For more information see “Setboot and System-wide Stable Storage ” (page 156).
• mkboot and LIF files
The mkboot command allows you to write to files in the LIF area on both Integrity and PA-RISC
servers; for example, the AUTO file. While on a vPars server, mkboot can still be used to write
to files in the LIF area. However, the LIF area is not read during the boot of an OS on a virtual
partition. Instead, only the information stored in the vPars partition database is read. (Note
that the files in the LIF area are still read when the system or nPartition boots).
To simulate the effect of an AUTO file for a virtual partition, use the vPars commands so that
the information is saved in the vPars partition database. For more information, see “The AUTO
File on a Virtual Partition” (page 160).
• shutdown and reboot commands
In a virtual partition, the shutdown and reboot commands shutdown and reboot a virtual
partition and not the entire nPartition.
Also, if a virtual partition is not set for autoboot using the autoboot attribute (see the
vparmodify(1M) manpage), the -r and -R options of the shutdown or reboot commands
will only shut down the virtual partition; the virtual partition will not reboot. In other words,
the virtual partition will halt when the autoboot attribute is not set. For more information, see
the vparmodify(1M) manpage.
For the -R and -r options of the shutdown and reboot commands, the virtual partition will
not reboot when there is a pending Reboot for Reconfiguration until all the virtual partitions
within the nPartition have been shutdown and the vPars Monitor has been rebooted; note that
-R sets a pending Reboot for Reconfiguration. Also, the requested reconfiguration will not
take place until all the virtual partitions within the involved nPartition have been shutdown and
the vPars Monitor has been rebooted.
For more information, see “Shutting Down or Rebooting a Virtual Partition” (page 153) and
“Shutting Down or Rebooting the nPartition (Or Rebooting the vPars Monitor)” (page 154).
• ioscan output
On a PA-RISC system, the ioscan output for vcn and vcs drivers show a value of NO_HW
in the S/W State column. On an Integrity server, these drivers do not appear in the ioscan
output. This is normal.
• intctl Command
The intctl command is an HP-UX tool that enables management of I/O interrupts among
the active CPUs. It can be installed from the HP-UX Software Pack but should be used only by
