Installing and Managing HP-UX Virtual Partitions (includes A.04.03)

• Ignite-UX Recovery and Expert Recovery

Beginning with vPars A.02.03, the creation of make_tape_recovery tapes is supported on vPars-enabled

servers. However, recoveries using these tapes must be done outside of the vPars environment; they

cannot be used to recover a system from within a virtual partition. For example, the tape cannot be used

with the vparboot -I command. See page 11 for a sample disaster recovery recipe that uses

make_tape_recovery.

Ignite-UX Recovery via make_net_recovery requires additional steps as noted in “Network and Tape

Recovery” on page 239.

Expert recovery works as documented in the Ignite-UX manual; however, you must account for the vPars

differences described in “Expert Recovery” on page 248.

For more information on using tape devices, see also the paper titled Booting, Installing, Recovery, and

Sharing in a vPars Environment from DVD/CDROM/TAPE/Network available at

http://docs.hp.com/hpux/11i/index.html#Virtual%20Partitions.

• Ignite-UX and other Curses Applications

On the virtual console, when using applications that use curses, such as the terminal versions of

Ignite-UX and SAM, do not press Ctrl-A to toggle to the console display window of another virtual

partition while you are still within the curses application. This is especially applicable when you are

using vparboot -I and the Ignite-UX application to install vPars. For more information on curses, see

the curses_intro (3X) manpage.

As with most curses applications, if you get a garbled display, you can press Ctrl-L to refresh the display.

• ServiceGuard

ServiceGuard is supported with vPars. However, because ServiceGuard is used to guard against hardware

failures as well as software failures, its functionality will be reduced if a cluster includes multiple virtual

partitions within the same server. Such configurations are not recommended. See the ServiceGuard

documentation for more information on running Service Guard with vPars.

• UPS (uninterruptible power supply) software

UPS hardware communicates with UPS software via the serial port. By default, a hard partition has only

one serial port. For a hard partition that runs vPars, the serial port can be owned by at most one virtual

partition. Therefore, on the hard partition, the UPS can communicate with only the virtual partition that

owns the serial port.

Alternately, the HP PowerTrust II-MR UPS product can be configured across virtual partitions using

network connections, providing all the virtual partitions reside on the same network.

• Processor Sets

vPars A.03.xx and earlier: you cannot specify a hardware path for an unbound CPU. Therefore, to avoid

unintentionally removing unbound CPUs from a non-default pset, initially create the partition that will

be running Processor Sets using only bound CPUs. Then, when you add or remove an unbound CPU, the

unbound CPU will be added to or removed from only the default pset.

• Glance and Openview Performance Agent (MeasureWare)

For correct reporting of CPU utilization, you need to run Glance and MeasureWare versions C.03.35. or

higher.
