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]

   su askplus
   grep vsdata_ /ASKPLUS/vsrvtcp.ini

If they do NOT exist, copy them from the existing vsrvtcp.ini on the old system OR do the following to add them and then compare them to the profiles on the old system

   su askplus
   cd /ASKPLUS/vsdata
   ./vsinstall

Verify again

   grep vsdata_ /ASKPLUS/vsrvtcp.ini

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
