Having another day of a system administrator boredom, we had a task to upgrade some Tivoli TSM Backup clients running on a 20+ machines powered by CentOS and RHEL Linux to prepare the systems to be on the latest patched IBM Spectrum Backup client version available from IBM. For the task of patching I've used a central server where, I've initially downloaded the provided TSM client binaries archives. From this machine, we have copied TivSM*.tar to each and every system that needs to be patched and then patched. The task is not too complex as the running TSM in the machines are all at the same version and all running a recent patched version of Linux. Hence to make sure all works as expected we have tested TSM is upgraded from 7.X.X to 8.X.X on one machine and then test 8.1.8 to 8.1.11 upgrade on another one. Once having confirmed that Backups works as expected after upgrade. We have proceeded to do it massively on each of the rest 20+ hosts.
Below article's goal is to help some lazy sysadmin with the task to prepare an TSM Backup upgrade procedure to standartize TSM Upgrade, which as many of the IBM's softwares is very specific and its upgrade requires, a bit of manual work and extra cautious as there seems to be no easy way (or at least I don't know it), to do the upgrade by simply adding an RPM repository and doing, something like yum install tivsm*.


0. Check if there is at least 2G free of space

According to documentation the minimum space you need to a functional install without having it half installed or filling up your filesystem is 2 Gigabytes of Free Memory on a filesystem where the .tar and rpms will be living.

Thus check what is the situation with your filesystem where you wills store the .tar archice and extract .RPM files / install the RPM files.

# df -h

1. Download the correct tarball with 8.1 Client

On one central machine you would need to download the Tivoli you can do that via wget / curl / lynx whatever is at hand on the Linux server.

As of time of writting this article TSM's 8.1.11 location is at
URL:

http://public.dhe.ibm.com/storage/tivoli-storage-management/maintenance/client/v8r1/Linux/LinuxX86/BA/v8111/

I've made a local download mirror of Tivoli TSM 8.1.11 here.
In case you need to install IBM Spectrum Backup Client to a PCI secured environment to a DMZ-ed LAN network from a work PC you can Download it first from your local PC and via Citrix client upload program or WinSCP upload it to a central replication host from where you will later copy to each of the other server nodes that needs to be upgraded.

Lets Copy archive to all Server hosts where you want it later installed, using a small hack

Assuming you already have an Excel document or a Plain text document with all the IPs of the affected hosts where you will need to get TSM upgraded. Extract this data and from it create a plain text file /home/user/hosts.txt containing all the machine IPs lined up separated with carriage return separations (n), so you can loop over each one and use scp to send the files.

– Replicate Tivoli tar to all machine hosts where you want to get IBM Spectrum installed or upgraded.
Do it with a loop like this:

# for i in $(cat hosts.txt); do scp 8.1.11.0-TIV-TSMBAC-LinuxX86.tar user@$i:/home/user/; done

 Copy to a Copy buffer temporary your server password assuming all your passwords to each machine are identical and paste your login user pass for each host to initiate transfer
 

2. SSH to each of the Machine hosts IPs

Once you login to the host you want to upgrade
Go to your user $HOME /home/user and create files where we'll temporary store Tivoli archive files and extract RPMs

[root@linux-server user]# mkdir -p ~/tsm/TSM_BCK/
[root@linux-server user]# mv 8.1.11.0-TIV-TSMBAC-LinuxX86.tar ~/tsm
[root@linux-server user]# cd tsm
[root@linux-server user]# tar -xvvf 8.1.11.0-TIV-TSMBAC-LinuxX86.tar
gskcrypt64-8.0.55.17.linux.x86_64.rpm
GSKit.pub.pgp
gskssl64-8.0.55.17.linux.x86_64.rpm
README_api.htm
README.htm
RPM-GPG-KEY-ibmpkg
TIVsm-API64.x86_64.rpm
TIVsm-APIcit.x86_64.rpm
TIVsm-BAcit.x86_64.rpm
TIVsm-BAhdw.x86_64.rpm
TIVsm-BA.x86_64.rpm
TIVsm-filepath-source.tar.gz
TIVsm-JBB.x86_64.rpm
TIVsm-WEBGUI.x86_64.rpm
update.txt

3. Create backup of old backup files

It is always a good idea to keep old backup files

[root@linux-server tsm]# cp -av /opt/tivoli/tsm/client/ba/bin/dsm.opt ~/tsm/TSM_BCK/dsm.opt_bak_$(date +'%Y_%M_%H')
[root@linux-server tsm]# cp -av /opt/tivoli/tsm/client/ba/bin/dsm.sys ~/tsm/TSM_BCK/dsm.sys_bak_$(date +'%Y_%M_%H')

[root@linux-server tsm]# [[ -f /etc/adsm/TSM.PWD ]] && cp -av /etc/adsm/TSM.PWD ~/TSM_BCK/ || echo 'file doesnt exist'

/etc/adsm/TSM.PWD this file is only there as legacy for TSM it contained encrypted passwords inver 7 for updates. In TSM v.8 encryption file is not there as new mechanism for sensitive data was introduced.
Be aware that from Tivoli 8.X it will return error
exist'

!! Note – if dsm.opt , dsm.sys files are on different locations – please use correct full path locations !!

4. Stop  dsmcad – TSM Service daemon

[root@linux-server tsm]# systemctl stop dsmcad

5. Locate and deinstall all old Clients

Depending on the version to upgrade if you're upgrading from TSM version 7 to 8, you will get output like.

[root@linux-server tsm]# rpm -qa | grep 'TIVsm-'
TIVsm-BA-7.1.6-2.x86_64
TIVsm-API64-7.1.6-2.x86_64

If you're one of this paranoid admins you can remove TIVsm packs  one by one.

[root@linux-server tsm]# rpm -e TIVsm-BA-7.1.6-2.x86_64
[root@linux-server tsm]# rpm -e TIVsm-API64-7.1.6-2.x86_64

Instead if upgrading from version 8.1.8 to 8.1.11 due to the Security CVE advisory recently published by IBM e.g. (IBM Runtime Vulnerability affects IBM Spectrum Backup archive Client) and  vulnerability in Apache Commons Log4J affecting IBM Spectrum Protect Backup Archive Client.

[root@linux-server tsm]# rpm -qa | grep 'TIVsm-'
TIVsm-API64-8.1.8-0.x86_64
TIVsm-BA-8.1.8-0.x86_64

Assuming you're not scared of a bit automation you can straight do it with below one liner too 🙂

# rpm -e $(rpm -qa | grep TIVsm)

[root@linux-server tsm]# rpm -qa | grep gsk
[root@linux-server tsm]# rpm -e gskcrypt64 gskssl64

6. Check uninstallation success:

[root@linux-server tsm]# rpm -qa | grep TIVsm
[root@linux-server tsm]# rpm -qa | grep gsk

Here you should an Empty output, if packages are not on the system, e.g. Empty output is good output ! 🙂

7. Install new client IBM Spectrum Client (Tivoli Storage Manager) and lib dependencies

[root@linux-server tsm]# rpm -ivh gskcrypt64-8.0.55.4.linux.x86_64.rpm
[root@linux-server tsm]# rpm -ivh gskssl64-8.0.55.4.linux.x86_64.rpm

 If you're lazy to type you can do as well

[root@linux-server tsm]# rpm -Uvh gsk*

Next step is to install main Tivoli SM components the the API files and BA (The Backup Archive Client)

[root@linux-server tsm]# rpm -ivh TIVsm-API64.x86_64.rpm
[root@linux-server tsm]# rpm -ivh TIVsm-BA.x86_64.rpm

If you have to do it on multiple servers and you do it manually following a guide like this, you might instead want to install them with one liner.

[root@linux-server tsm]# rpm -ivh TIVsm-API64.x86_64.rpm TIVsm-BA.x86_64.rpm

There are some Not mandatory "Common Inventory Technology" components (at some cases if you're using the API install it we did not need that), just for the sake if you need them on your servers due to backup architecture, install also below commented rpm files.

## rpm -ivh TIVsm-APIcit.x86_64.rpm

## rpm -ivh TIVsm-BAcit.x86_64.rpm

These packages not needed only for operation WebGUI TSM GUI management, (JBB) Journal Based Backup, BAhdw (the ONTAP library)


— TIVsm-WEBGUI.x86_64.rpm
— TIVsm-JBB.x86_64.rpm
— TIVsm-BAhdw.x86_64.rpm

8. Start and enable dsmcad service

[root@linux-server tsm]# systemctl stop dsmcad

You will get

##Warning: dsmcad.service changed on disk. Run 'systemctl daemon-reload' to reload units.

[root@linux-server tsm]# systemctl daemon-reload

[root@linux-server tsm]# systemctl start dsmcad


## enable dsmcad – it is disabled by default after install

[root@linux-server ~]# systemctl enable dsmcad

[root@linux-server tsm]# systemctl status dsmcad

9. Check dmscad service is really running

Once enabled IBM TSM will spawn a process in the bacground dmscad if it started properly you should have the process backgrounded.

[root@linux-server tsm]# ps -ef|grep -i dsm|grep -v grep
root      2881     1  0 18:05 ?        00:00:01 /usr/bin/dsmcad

If process is not there there might be some library or something not at place preventing the process to start …

10. Check DSMCAD /var/tsm logs for errors

After having dsmcad process enabled and running in background

[root@linux-server tsm]# grep -i Version /var/tsm/sched.log|tail -1
12/03/2020 18:06:29   Server Version 8, Release 1, Level 10.000

 

[root@linux-server tsm]# cat /var/tsm/dsmerror.log

To see the current TSM configuration files we can  grep out comments *

[root@linux-server tsm]# grep -v '*' /opt/tivoli/tsm/client/ba/bin/dsm.sys

Example Configuration of the agent:
—————————————————-
   *TSM SERVER NODE Location
   Servername           tsm_server
   COMMmethod           TCPip
   TCPPort              1400
   TCPServeraddress     tsmserver2.backuphost.com
   NodeName             NODE.SERVER-TO-BACKUP-HOSTNAME.COM
   Passwordaccess       generate
   SCHEDLOGNAME         /var/tsm/sched.log
   SCHEDLOGRETENTION    21 D
   SCHEDMODE            POLLING
   MANAGEDServices      schedule
   ERRORLOGNAME         /var/tsm/dsmerror.log
   ERRORLOGRETENTION    30 D
   INCLEXCL             /opt/tivoli/tsm/client/ba/bin/inclexcl.tsm

11. Remove tsm install directory tar ball and rpms to save space on system

The current version of Tivoli service manager is 586 Megabytes.

[root@linux-server tsm]# du -hsc 8.1.11.0-TIV-TSMBAC-LinuxX86.tar
586M    8.1.11.0-TIV-TSMBAC-LinuxX86.tar

Some systems are on purpose configured to have less space under their /home directory,
hence it is a good idea to clear up unnecessery files after completion.

Lets get rid of all the IBM Spectrum archive source files and the rest of RPMs used for installation.

[root@linux-server tsm]# rm -rf ~/tsm/{*.tar,*.rpm,*.gpg,*.htm,*.txt}

12. Check backups are really created on the configured remote Central backup server

To make sure after the upgrade the backups are continuously created and properly stored on the IBM Tivoly remote central backup server, either manually initiate a backup or wait for lets say a day and run dsmc client to show all created backups from previous day. To make sure you'll not get empty output you can on purpose modify some file by simply opening it and writting over without chaning anything e.g. modify your ~/.bashrc or ~/.bash_profile

## List all backups for '/' root directory from -fromdate='DD/MM/YY'

[root@linux-server tsm]# dsmc

    Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Firefox/68.0

    Import note to make to prevent you from scaring out yourself is that if you have tested with

    dsmc client to connect to the Central backup location server and mistyped some command in the TSM CLI like typed q instead of quite or tried to get out of the program with CTRL + D

    You will end up with a strange log messages in dsmerror.log like:
     

    # tail -n 500 dsmerror.log
    12/04/2020 15:34:49 ANS1141W Unknown command – exit
    12/04/2020 15:37:50 ANS1141W Unknown command – exit
    12/04/2020 15:38:41 ANS1141W Unknown command – exit

    This is normal and you don't need to worry about. Another thing if you use some kind of data integrity security checking software such as samhain is to update the database because some files will change on the file system.
    If you use samhain and add the newly extracted Tivoli TSM rpm package files run:

    samhain -l none -t update –foreground –set-mail-severity=none –set-print-severity=notice
