Vital Signs HPUX Server Migration

Overview

This document will present a scenario of migrating an existing Vital Signs install from a PA-RISC HPUX system to an ITANIUM HPUX system.

Step 1 - Software Dependencies

The following software is required to be installed prior to running Vital Signs.

-AskPlus 8.3.3+

-Python 2.7.3

-Python ConfigObj library

Step 2 - File Migration

The following folders should be migrated from the old HPUX system to the new one retaining their file permissions.

- /ASKPLUS/vsdata

- /var/summit/spectrum/LIVE/vsdata

This is possible using the scp command with -rp, r stands for recursive copy and p stands for preserve.

Example scp of /ASKPLUS/vsdata

   su askplus
   scp -rp /ASKPLUS/vsdata askplus@192.168.1.xxx:/ASKPLUS/vsdata

Example scp of /var/summit/spectrum/LIVE/vsdata

   su bolive
   scp -rp /var/summit/spectrum/LIVE/vsdata bolive@192.168.1.xxx:/var/summit/spectrum/LIVE/vsdata

Step 3 - Link Creation

A symbolic link for the jobs directory should be created as root on the new system

   su root
   ln -fs /ASKPLUS/vsdata/jobs /VSJOBS

Step 4 - Verification

Verify that the following profiles exist in the /ASKPLUS/vsrvtcp.ini file

- [vsdata_test]

- [vsdata_live]

- [vsdata_test_eom]

- [vsdata_live_eom]

- [vsdata_test_restore]

- [vsdata_live_restore]

Verify that the following files have 755 permissions

- /ASKPLUS/vsdata/scripts/vsftp - /ASKPLUS/vsdata/scripts/vsreload

   $ ls -l /ASKPLUS/vsdata/scripts/vs*
   -rwxr-xr-x   1 askplus    users         7951 Oct 17 10:23 /ASKPLUS/vsdata/scripts/vsftp
   -rwxr-xr-x   1 askplus    users        11633 Sep  6 11:07 /ASKPLUS/vsdata/scripts/vsreload

Verify that the /VSJOBS link exists

   $ ls -l /VSJOBS
   lrwxr-xr-x   1 root       sys             20 Apr 21  2011 /VSJOBS -> /ASKPLUS/vsdata/jobs
