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

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.

Note: this section applies only to the rp5470/L3000 and rp7400/N4000 servers. You can skip this section for nPartitionable servers.

The Guardian Service Processor (GSP) provides multiple access methods for the console: the hardware console port, the remote-modem port, and the LAN console port. To avoid mismatches in terminal emulation which can cause strange results on your display, it is important to match the display type as set in the GSP to the display type of the terminal or terminal emulator that you are using. For example:

How to Set the GSP Terminal Type

1. Access the GSP through the lan console, the remote-modem port, or a physically connected terminal.

2. Use the CA command at the GSP prompt to modify the console attributes:

   GSP> ca

3. Answer “y” (yes) to indicate that you want to change the console port settings:

   Do you want to modify the Local Console Serial Port settings? (Y/[N]) y

4. Answer “n” (no) to the questions about modifying the “Serial Port bit rate” and the “Current Flow Control”

   Current Local Console Serial Port bit rate: 9600 bits/s Do you want to modify it? (Y/[N]) n Current Flow Control: Software Do you want to modify it? (Y/[N]) n

5. Indicate which terminal type you want to use, then answer “y” (yes) to confirm your change:

   Enter Terminal Type ([Vt100] / Hpterm): New Terminal Type: hpterm Confirm? (Y/[N]): y -> Terminal Type will be updated.

6. Answer n (no) to the question about updating the “Remote Console Serial Port Modem settings”:

   Do you want to modify the Remote Console Serial Port Modem settings? (Y/[N]) n

You will see a message indicating the command execution will take a few seconds and then a message indicating that your settings have been updated.

The virtual partitions that you create will use this terminal-type setting for their virtual console displays.

	TIP: If you get a garbled display, you can press Ctrl-L to refresh the display.

Due to the vPars files that will exist in /stand, you should increase your planned size of the /stand file system by 100 MB. For example, if you originally had planned to create /stand with 1 GB for your HP-UX instance, you should plan for 1.1 GB when that HP-UX instance resides in a virtual partition.

To avoid hangs on VxFS file systems, install kernel patch PHKL_27121 or its successor on the operating systems of each virtual partition. This patch is available from the IT Resource Center website at http://itrc.hp.com.

Before installing the SecurePath product, install the vPars product and create and install all the virtual partitions.

	NOTE: The SecurePath product is not supported on HP-UX 11i v3 (11.31). Use the native multipathing available with the HP-UX 11i v3 mass storage stack, as described in the white paper The Next Generation Mass Storage Stack. This paper can be found in the Network and Systems Management section of http://docs.hp.com, under Storage Area Management.
