DP 5.0 Cell Manager and Installation Server not supported on HP-UX 10.x
Data Protector GUI is no longer supported on the following systems:
–HP-UX 10.x
–Windows ME
–Windows 98
New San support strategy
Current status:• Weakness in SAN coverage• Restricted Support in SAN• Support issues
Goal:• Should work in any SAN supported by specific
vendor• Ability to easily identify and isolate problems
DP 5.0 offers two ways to support SAN solutions:
• HP Solution (as offered by NSS)• 3rd party solution after successful test (DTT tool)
Device Test Tool
• utility used for testing the basic functionality of standalone SCSI devices
• using simplest command –cmdfile,
• includes two automation scripts with a set of commands.
• expects the device filename as an input using the –
device option
• two commands required: cmdfile and type
Device Test Tool - supported platforms
• Windows 95/98 • Windows 2000• Windows XP• Windows NT• HP-UX 10.20,
11.x• Solaris 7, 8

Installation ServerTarget platform Installation toolsUnix Windows
HP-UX swinstall, swremove
Solaris pkgadd, pkgrm
Other Unix omnisetup 1
Windows Microsoft Installer
Novell Install script
MPE/iX ftp, unpack
1) Installation server does not support Dynix, SCO Unixware 7.1.1 client
Installation methods (2)
•New install script for local installation of Unix clients: omnisetup.sh
•Applies only for non HP-UX 11.x and non Solaris Unix clients•omnisetup.sh [-source directory] [-server name]
[-install component-list]-directory is the location where installation CD is mounted.
If not specified, current directory is taken.-name is an optional name of the cell server host.-component-list is a comma-separated list of component
codes. No spaces are allowed, and core and core-integ components need not to be specified.
•Located on CD for HP-UX, in directory LOCAL-DP-AGENT-INSTALL
•Only ksh shell is supported•Detects and upgrades previously installed components•Checks and validates specified components•Client host can be imported automatically
Limitations / drawbacks
•DP 5.0 CM and GUI not supported on HP-UX 10.20•No DP 5.0 CD for HP-UX 10.20•Installation server not supported on Windows XP•’Automatic disaster recovery’ module only
installable on Windows platform •No Japanese, German and French localization
Migration aspects
•No license migration required ! Only support contract migration
•IDB structure unchanged, but new Velocis DB version•Direct upgrade is possible for:
-OB II A.03.51 -> Data Protector A.05.00-OB II A.04.00 -> Data Protector A.05.00-OB II A.04.10 -> Data Protector A.05.00
•Upgrade from other Omniback II versions:-first upgrade to OB II 4.x required-OBII 3.x -> OBII 4.x -> DP 5.0 (possible, but not
recommended)-direct upgrade from OBII 3.x -> DP 5.10 planed with
DP 5.10
Upgrade considerations
Requirements to consider:•CM, IS and clients must have same version installed (DP 5.0)•In MoM environment all CM must have same version installed (DP
5.0)•Licenses of OB II A.03.x and 4.x still valid in DP 5.0
no license migration needed•Important: upgrade procedures are different on HP-UX, Solaris
and Windows platform- on HP-UX and Solaris: first remove old, then install new
binaries IDB and configuration data will not be removed
- on Windows do NOT remove/uninstall old binaries ! otherwise IDB and configuration data will be
removed•Upgrade order: 1. Upgrade cell manager and all installation
servers 2. Upgrade all clients, can be done gradually 3. MA / Integration Agents must be upgraded before start of any backup / restore
Upgrade scenarios (1)
Upgrade from OBII A.04.x => DP A.05.00
•Standard upgrade procedure applies•Upgrade consist of conversion to new Velocis DB version
(2.0 -> 3.5)•IDB data files will not be modified•IDB upgrade started automatically after installation, no user interaction required•SW install and remove utility is swremove / swinstall on HP-
UX and MSI on Windows•IDB upgrade very fast•Upgrade status reported in upgrade.log file
Upgrade scenarios (2)
Upgrade OBII 4.x CM on HP-UX 10.20 => DP 5.0 on HP-UX 11.x
•DP 5.0 does NOT support CM and GUI on HP-UX 10.20•Upgrade procedure needs to incorporate upgrade of HP-UX to
11.x•Order of upgrade steps very important:
1. Remove OBII 4.x binaries from HP-UX 10.20 CM (swremove)2. Keep IDB and configuration data untouched3. Upgrade system OS to HP-UX 11.x4. Install DP 5.0 binaries (using swinstall)5. Installation process automatically upgrades IDB
IDB Upgrade Wizard - detail part (1)
This upgrade wizard offers three options to proceed:• Upgrade detail part of IDB• Postpone the detail upgrade• Skip the upgrade and finish installation
IDB Upgrade Wizard - detail part (2)
This upgrade wizard checks:• OBII 3.51 database• Disk space required for detailed upgrade
IDB Upgrade Wizard - detail part (3)
This upgrade wizard allows:• Add extension files for filename table spaces• Add directories for binary files (DCBF directories)
IDB Upgrade Wizard - detail part (4)
This upgrade wizard provides:• Estimated time required to perform the detail upgrade• Allows to monitor the progress of the detail upgrade

1. The application writes data to the array, using RAID to control distribution of the data across physical disks.
2. Backup session starts.
3. DB/Application is put into backup mode/offline.
4. A snapshot is taken: Snapshot data is written to the array, again using RAID to control distribution of the data across physical disks.
5. DB/Application is taken out of Backup mode/put back on-line.
6. If a tape backup is specified, the snapshot of data is backed up to tape
7. Backup session ends.

what it isallows a backup application to move data directly from disk arrays to tape drives or libraries over the SAN, bypassing the application server
benefit • zero impact and downtime upon
applications during backup operations
• more efficient backup & recovery within a SAN due to an integrated data mover
within the hp StorageWorks tape libraries with hp OV Data Protector (split-mirror & direct backup extensions for all xp arrays)
or within the XP disk array with VERITAS NetBackup (Array Integration option & ServerFree Agent products) for xp 128 & xp 1024
