Announcements for HP-UX 11i v3
Serviceguard A.11.19 supports HP-UX 11i v3, which introduces important
improvements, particularly in regard to the I/O subsystem. See the subsections that
follow, and “What’s in this Release” (page 19).
New Bundles
Serviceguard A.11.19 is now available as a recommended product in the HP-UX 11i v3
HA-OE and DC-OE bundles.
Native Multipathing, Veritas DMP, and Related Features in HP-UX 11i v3
The HP-UX 11i v3 I/O subsystem provides multipathing and load balancing by default.
This is often referred to as native multipathing.
Veritas Volume Manager (VxVM) and Dynamic Multipathing (DMP) from Symantec
are supported on HP-UX 11i v3, but do not provide multipathing and load balancing;
DMP acts as a pass-through driver, allowing multipathing and load balancing to be
controlled by the HP-UX I/O subsystem instead.
When you upgrade a system to HP-UX 11i v3, the I/O subsystem by default will start
performing load balancing and multipathing for all multipath devices (whether or not
they are managed by VxVM/DMP, and whether or not you decide to migrate the system
to agile addressing); you do not have to take any additional steps to make this happen.
For more information about multipathing in HP-UX 11i v3, see the white paper HP-UX
11i v3 Native Multipathing for Mass Storage, and the Logical Volume Management volume
of the HP-UX System Administrator’s Guide in the HP-UX 11i v3 Operating
Environments collection at http://docs.hp.com. See also “About Device Special
Files (DSFs)” (page 43).
PV Links
Previous editions of Managing Serviceguard recommended creating LVM PV links for
LUNs defined in disk arrays. On HP-UX 11i v3, these PV Links are redundant; they
are supported, but will be inactive unless you turn off native multipathing (in that case
they will function as they did in previous releases of HP-UX).
PCI Error Recovery
PCI Error Recovery enables an HP-UX system to detect, isolate, and automatically
recover from a PCI error. PCI Error Recovery is enabled on HP-UX 11i v3 systems by
default, but HP recommends that it remain enabled in a Serviceguard cluster only if
your storage devices are configured with multiple paths and you have not disabled
HP-UX native multipathing.
