10 Using Dynamic Root Disk for patch management
This chapter introduces the HP-UX Dynamic Root Disk (DRD) tool for patching HP-UX systems and
reducing system downtime.
DRD provides you with the ability to clone an HP-UX system image to an inactive disk, and then:
• perform system maintenance on the clone while your HP-UX 11i system is online.
• automatically synchronize the active image and the clone, eliminating the need to manually
update files on the clone.
• quickly reboot during off-hours – after the desired changes have been made – significantly
reducing system downtime.
• utilize the clone for system recovery, if needed.
• rehost the clone on another system for testing or provisioning – only on VMs or blades running
HP-UX 11i v3 LVM, and VMs running HP-UX 11i v2 LVM.
• perform an OE Update on the clone from an older version of HP-UX 11i v3 to HP-UX 11i v3
Update 4 or later.
Currently DRD is supported in the following environments:
• HP-UX 11i v3 (B.11.31) September 2007 Release or later
• HP-UX 11i v2 (B.11.23) September 2004 Release or later
• Logical Volume Manager (LVM) 1.0
• VxVM 4.1
• VxVM 5.0
• An extra disk beyond the requirements to run the operating system. The disk should be local
or a SAN and large enough to contain the root volume group.
DRD is a set of commands with which you can clone the active system root volume group, install
and manage patches (11i v2 and v3) and products (11i v3 only) on the clone, then boot the clone
as the new active system.
You can use DRD to manage patches and products when the following criteria apply to your
environment:
1. There is a desire to limit downtime.
2. The patches and products being installed would require a reboot anyway.
3. The system being managed is running HP-UX 11i v2 (B.11.23) September 2004 Release or
later, or the HP-UX 11i v3 (B.11.31) September 2007 release or later.
4. A local or SAN disk large enough to contain the root volume group is available.
5. The root volume group can be, but does not need to be mirrored.
DRD is not useful when the following criteria apply to your environment:
1. The downtime for software maintenance is not an issue.
2. The patches and products being managed do not require a reboot, and apply to programs
that can be stopped during the installation/removal of the patch.
3. The system being managed is not running HP-UX 11i v2 (B.11.23) September 2004 Release
or later, or the HP-UX 11i v3 (B.11.31) September 2007 release or later.
4. An extra disk that is large enough to hold the root volume group is not available.
