HP-UX Virtual Partitions Administrator's Guide (includes A.04.06 and A.05.04)

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 151).
• “vPars Monitor: Booting the vPars Monitor” (page 130).
• “Booting a Virtual Partition” (page 154)
• “Shutting Down or Rebooting the nPartition (Or Rebooting the vPars Monitor)” (page 156)
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 110).
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.
Other Considerations
This section covers:
• “Installing Server Firmware on non-nPartitionable Servers” (page 68)
• “Setting the GSP Terminal Type” (page 69)
• “Increase in Size of /stand File System” (page 70)
• “VxFS (Veritas File System) (vPars A.03.xx)” (page 70)
Installing Server Firmware on non-nPartitionable Servers
Installing Firmware for the systems running vPars must be done in a standalone (PA-RISC) or
nPars (Integrity) mode. Once in standalone or nPars mode, the procedure for installing firmware
on a system with vPars installed is the same as a system without vPars installed. Additional
information is shown below. For information on specific firmware versions for your servers, see
the HP-UX Virtual Partitions Ordering and Configuration Guide.
• Non-nPartitionable Systems On the rp5470/L3000 and rp7400/N4000 servers, for firmware
patches to take effect in a vPars environment, follow this procedure:
1. Shut down all the virtual partitions.
2. Reboot the server into standalone mode using the primary path. This consists of the
