v3) Considerations in vPars

o Detect an HP-UX 11i v3 boot disk using the EFI paths displayed at the EFI shell. The

hardware path to EFI path mapping can be obtained by using the –e option to

ioscan(1M) or by using vparefiutil(1M) on a virtual partition in that hard partition (if it

is up) to see the EFI path mapping to an HP-UX 11i v3 boot disk.

• Flexible administration and mixed HP-UX 11i v1/v2/v3 vPars environment

implications: The vPars Flexible Administrative Capability feature restricts the usage of

specific vPars commands such that they can be successfully executed from only designated

virtual partitions. In a mixed HP-UX 11i v1/v2/v3 vPars environment, it is recommended that

you choose an HP-UX 11i v3 virtual partition as a designated virtual partition, otherwise the

designated virtual partition (running HP-UX 11i v1 or v2) will have limited capabilities since

not all vPars commands can execute on it. Specifically, the vPars commands vparcreate,

vparmodify, and vparremove on other virtual partitions are not allowed from a HP-UX 11i v1

or v2 virtual partition.

• PCI Error Handling and Error Recovery implications: HP-UX 11i v2 supports PCI

Error handling and HP-UX 11i v3 supports PCI Error Recovery in addition to Error Handling.

Please refer to the PCI Error Handling Product Note for additional info on this. Please note

that not all I/O cards and not all platforms support this feature. Also note that it is possible

that more cards/drivers will support Error Handling and Recovery on HP-UX 11i v3 than on

HP-UX 11i v2. So, it is possible that a card/driver which does not support this functionality

could bring down the hard partition including all the virtual partitions if there is a failure.

• Unsupported I/O cards: HP-UX 11i v3, HP-UX 11iv2, or HP-UX 11i v1 may support

certain I/O cards which are not supported on all HP-UX releases. Care must be taken to

ensure that the virtual partitions are configured such that only cards that are supported by the

OS version configured in the virtual partition are included in that virtual partition’s definition.

Please refer to the HP-UX Virtual Partitions Ordering and Configuration Guide to ensure that

the virtual partitions are configured with supported I/O cards.
