Note
The “Typical configuration examples” section of this whitepaper explains
how to prepare an existing homogeneous cluster for mixed cluster support.
– A non-MCOE based system with HP Serviceguard version A.11.16 or newer
• Same or similar patch set for operating system, HP Serviceguard, and ISV applications
• Same version of volume manager software (if used for shared storage)
– Logical Volume Manager (LVM)
– Veritas Volume Manager (VxVM) starting with version 3.5
– Veritas Cluster Volume Manger (CVM) starting with version 3.5
• Same version of file system software (if used for shared storage)
HP journal file system (JFS) / Veritas file system (VxFS) version 3.5 with file system layout 5 is
shipped with HP-UX 11i v2UD2. This software version is compatible to file systems created with a
previous layout. If a VxFS file system was created on HP-UX 11i v1, it is layout 4 based. It can be
used as-is on HP-UX 11i v2UD2 or converted to layout 5. However, if it is converted to layout 5, it
cannot be used with an HP-UX 11i v1 system anymore.
• Same version and bundle of the HP Serviceguard Storage Management Suite starting with
Serviceguard A.11.17
Currently HP ships the HP Serviceguard Storage Management suite version A.01.00 which is based
on release 4.1 of Veritas volume manager and file system (VxVM, CVM, VxFS, and CFS) products.
This version is only available on HP-UX 11i v2. Version A.02.00 is based on release 5.0 of the
Veritas products and will ship with Serviceguard A.11.18 in 2007 – first on HP-UX 11i v2 and later
on HP-UX 11i v3. Please refer to the individual HP Serviceguard Storage Management release
notes for details of the supported OS version.
Each release of the Storage Management Suite comes in different bundles, generally referred to as
bundle 1 through bundle 7.
If a Storage Management Suite bundle is used in a mixed Serviceguard cluster, the same version of
the same bundle needs to be installed on all cluster nodes. This is a general requirement which also
applies to homogeneous Serviceguard clusters.
Application software requirements
HP can only provide guidelines on how to configure applications in a mixed HP 9000 / Integrity
cluster. It is up to the individual application vendor or the customer, in the case of self-developed
applications, to actually approve and support the configuration.
Application code
HP-UX 11i v2UD2 supports applications that have been compiled in 32- and 64-bit mode on both HP
9000 and Integrity systems, which leads to four possible formats of executables (also called binaries).
Each format is identified by the operating system through its magic number (two bytes at the
beginning of a binary file identifying the type of the file). All four forms of executables can run on HP
Integrity systems—the Intel® Itanium® executables run natively, and the PA-RISC executables run
through the Aries binary emulator on Integrity servers. Only native PA-RISC executables can run on HP
9000 systems. The following table shows the possible combinations.
