Messages: errors, warnings, and notes
While the HP-UX 11i v3 install or update progresses, you will see progress messages
that are being entered into the log file. These messages usually refer to normal behavior.
The ERROR, WARNING, and NOTE messages, however, have the following significance:
ERROR
Indicates a serious problem, usually requiring action from you so that the
installation can proceed.
WARNING
Indicates something out of the ordinary, but not fatal. The warning may
require action from you.
NOTE
Indicates useful information you should take note of, but not fatal. The
note does not require action from you.
Special considerations
In this section, you will find several situations and scenarios that you should give
careful consideration before cold-installing or updating to HP-UX 11i v3. These
situations may affect the decisions you make during the next steps in the cold-install
and update process.
Reducing downtime using Dynamic Root Disk
With the HP-UX system administration toolset, Dynamic Root Disk (DRD), you can
clone an HP-UX system image to an inactive disk. Then you can:
• perform system maintenance on the clone while your HP-UX 11i system is online
• update from an older version of HP-UX 11i v3 to HP-UX 11i v3 March 2009 (Update
4) or later
• quickly re-boot during off hours once the desired changes have been made
• utilize the clone for system recovery, if needed
• rehost the clone on another system for testing or provisioning purposes (on VMs
or blades utilizing Virtual Connect; LVM only)
NOTE: Rehosting capabilities for HP-UX 11i v2 are different than for those of HP-UX
11i v3. For information, see the Dynamic Root Disk System Administrator's Guide for
HP-UX 11i v2, 11i v3, available at http://www.hp.com/go/drd (click Dynamic Root
Disk Web Site).
Administrators can use DRD to reduce downtime for system maintenance by creating
an inactive clone of the booted system, then applying patches and products to the clone.
The modified clone can then be booted at a convenient time. DRD supports both HP
Logical Volume Manager (LVM) and Veritas (VxVM) root volumes, except where
specifically noted above, and runs on both HP-UX 11i v2 and v3.
