The following article presents basic information on the available resources for HP-UX 11i v3 Migration.

Extensive changes were performed on the latest release of HP-UX 11i. From available software bundles and packaging to LVM 2.0 and the new Mass Storage Stack (Agile View naming, Native Multipathing) to the use of Dynamic Root Disk (DRD) and Software Assistane (SWA) as primary upgrade backup and patch assesments tools, the challange for HP-UX shops and System Administrators to adjust to this major changes can be challenging.

System Administration Manager (SAM) is deprected in favor of System Management Homepage web and text based tools. New features are added, but some others are removed or waiting to be migrated too.

New Software Bundles

  • New HP-UX 11i v3 Operating Environments
Pre-packaged OEs make this the most versatile, easy-to-deploy HP-UX ever
"HP announces the discontinuance of the original HP-UX 11i v3 OEs (FOE, EOE, and MCOE) effective October 31, 2008. From November 1, 2008 onward, only the new HP-UX 11i v3 OEs (Base OE, Virtual server OE, High Availability OE, and Data Center OE) will be available on HP 9000 and HP Integrity servers. There is no change to the timelines for HP-UX 11i v1 and HP-UX 11i v2 OEs".
"Your HP support contract entitles you to upgrade to HP-UX 11i v3 and to the new OEs for no additional cost... Your original OE ... ...entitles you to the corresponding OE on the right. Check it out and you'll see that, in all cases, you've just gained additional software at no additional cost".

Storage Area Management

"HP-UX 11i v3 introduces a new representation of mass storage devices called the agile view. The central idea of the agile view is that disk and tape devices are identified by the actual object via its World Wide Identifier (WWID) and not by a path to the device. Paths to a device can change dynamically, and multiple paths to a single device can be transparently treated as a single virtualized path, with I/O distributed across those multiple paths. This representation increases the reliability, adaptability, performance, and scalability of the mass storage stack, all without the need for operator intervention".

Dynamic Root Disk

"Dynamic Root Disk (DRD) is a software tool containing a set of commands that enable you to clone a system image to another hard disk and modify the image without shutting down the system. DRD significantly reduces system downtime and allows you to do software maintenance during normal business hours.
Using DRD, you can perform software maintenance on the cloned (inactive) system image without affecting the active system image. When modifications are complete, you can boot the cloned system image on the original system or on a different system. If you do not want to use the cloned system image immediately, you can leave it in place to be utilized at a later time.
Other uses of DRD include using the clone for quick software recovery or using the clone to boot another system, which is referred to as rehosting. For details of rehosting, see Rehosting and Unrehosting Systems".

Software Assistant

HP-UX Software Assistant (SWA) is a command-line based tool that consolidates and simplifies patch management and security bulletin management on HP-UX systems. The SWA tool is new for HP-UX releases as of January 2007, supersedes Security Patch Check (SPC), and is the HP-recommended utility to use to maintain currency with HP-published security bulletins for HP-UX software.
