Installing, Updating, or Removing vPars and Upgrading Servers with vPars

Notes, Cautions, and Other Considerations Before You Update or Install vPars

Chapter 4

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. Please read the section “Planning, Installing, and Using vPars with an nPartitionable Server” on

page 56 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” on page 73

• “Setting the GSP Terminal Type” on page 74

• “Increase in Size of /stand File System” on page 75

• “VxFS (Veritas File System) (vPars A.03.xx)” on page 75

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 following:

a. At the MON> prompt, type reboot

b. If needed, interrupt the boot sequence at the BCH>, and using the primary path, boot

/stand/vmunix instead of /stand/vpmon. For example:

BCH> bo pri

interact with IPL? y

ISL> hpux /stand/vmunix

NOTE The server must be in standalone mode for the patches to take effect, so please do not

skip this step.
