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

For more information on booting and boot devices on PA-RISC systems, see also the paper titled
Booting, Installing, Recovery, and Sharing in a vPars Environment from DVD / CDROM / TAPE /
Network available on the BSC website at:
www.hp.com/go/hpux-vpars-docs
For information on using the vPars commands, see the following sections in the chapter vPars
Monitor and Shell Commands:
• “Managing: Creating a Virtual Partition” (page 150).
• “vPars Monitor: Booting the vPars Monitor” (page 132).
• “Booting a Virtual Partition” (page 153)
• “Shutting Down or Rebooting the nPartition (Or Rebooting the vPars Monitor)” (page 154)
Server Chipset Upgrade
The process documented in many of the updates assumes you are not performing a hardware
upgrade that causes a change in hardware paths (for example, upgrading from the sx1000 chipset
to the sx2000 chipset). For information on upgrading vPars when the upgrade includes a hardware
path change, see “Upgrading Integrity Servers from the sx1000 to sx2000 Chipset” (page 112).
Cautions
Hardware Paths on the vPars Command Line
— Hardware Path Differences Between Cellular (nPartitionable) and Non-cellular Systems
The hardware paths for some example system are formatted for non-cellular systems. For
cellular systems, their hardware paths contain the prefix of the cell number. Therefore, on
non-cellular systems, the path 0/0 refers to a SBA/LBA format. However, on cellular systems,
the path 0/0 refers to a cell/SBA format. Read the section “Planning, Installing, and Using
vPars with an nPartitionable Server” (page 49) if you are using a cellular system.
— Path Formats on the vPars Command Line
For vPars A.03.01 or earlier, you must explicitly specify the LBA for I/O allocation. Thus, for
cellular systems on A.03.01 or earlier, you must use the cell/SBA/LBA format on the command
line. If you use only the cell/SBA format the vPars commands will not assume that all LBAs
under the specified SBA are to be included in the allocation. Doing so may cause the system
to panic.
For vPars A.03.02 or later, you can use either the cell/SBA or cell/SBA/LBA format on the
command line. The vPars commands will assume the command applies to all LBAs under the
specified SBA.
— When OE is installed in vPar mode by excluding the vPars bundle from the OE, system boot
fails
Installing a vPar in vPar mode by selecting the HP-UX OE without selecting vPars bundle is not
supported. So, always install the OE along with the vPars bundle in the vPar mode. If you try
to boot a system that has the OE installed in vPar mode where the vPars bundle was not
selected, the system will fail to boot up.
