Action plan

####vg_name_change.sh >> rename vg from system to sles 11 
####sle11to12 >> replace important configuration, set network, hostname, join server to BASF AD, reregister server to APX and HPSA.

Prerequsits:
Before replace system VMDK's.
This is very importamt for furder operation, because both server have the same system VG names ( system).

1.Change system volume group from system to suse11  
./vg_name_change.sh system sles11
2.Check if the name is successful rename.
vgs
PS:If VG namas are diferent this action is not required.
2.Unregister server from suse-manager.
From suse-mgr01 execute ./register-to-SUSE-Manager.sh -e -s servername
./register-to-SUSE-Manager.sh -e -l sles11to12
3.Unjoined server from BASF domain.
lxinfra01:/home/unxtools/ADJOIN/ADJOIN_LOCAL/basfad_join2AD.sh -u servername 
4.Unregister server form APX:
/opt/apxpccp/pccprel exec,DCM/DCM_DEREG_$(hostname).scp
/opt/apxpccc/pccCrel exec,DCM/DCM_DEREG_$(hostname).scp
5.Unregister server from HPSA.
/opt/opsware/agent/bin/agent_uninstall.sh --no_deactivate --force

 
After VMDK replasment:

All scripts and binary files are putted in /root/scripts/sles_migration/
1.Go to a direcrtory and axecute:

./sle11to12 old_vg new_vg hostname

2.Go to a suse-mgr01 in directory /infra/linux/SuSE-manager and join server 
./register-to-SUSE-Manager.sh -r -s sles11to12

Inform colleagues from BASF to proceed with further action.













for s in $(cat /usr2/local/sles11o12); do ./basfad_join2AD.sh -u $s;done
group is infra-ITIS

4.Stop server detach root vmdk from first iscs controller, attach root disk with sles12 vmdk on the iscso0:0.
Attach sles11 vmdk on the last iscs controller and power on the server.



6.Register server to suse-manager.
./register-to-SUSE-Manager.sh -r -s sles11to12

7.SAP and Oracle colleagues will install new DB and application versions and check if application, databases running correct. 








Scripts vg_name_change.sh, sles12_sap_ora_conf.sh, I test them on my lab but we can check if they work correct next week.

How to hpsa agent work?

#remove HPSA agent script
/opt/opsware/agent/bin/agent_uninstall.sh --no_deactivate --force
rm -r /opt/opsware
$OPSPACKAGE --loglevel info --opsw_gw_addr_list 10.92.96.41:3001 -f --force_new_device


Scripts that will be needed to sles11 to sles 12 migration


vg_name_change.sh
basfad_join2AD.sh
$OPSPACKAGE - hpsa agent elf package
sles12_sap_ora_conf.sh

Directory where the scripts putted  ~/sles_migration/ it a part from dimetrge home directory.


Hello Georgi,
 
here the deregister / register for APX
 
Deregister:
 
The deregister can be run on the suse-mgr01 (Works from every server)
Just replace <SERVER> with the server name.
 
/opt/apxpccp/pccprel exec,DCM/DCM_DEREG_$(hostname).scp
/opt/apxpccc/pccCrel exec,DCM/DCM_DEREG_$(hostname).scp
 
 
 Мисля, че в този случай:
а) Прехвърляне на потребители на OS SLES11, които са остарели / вече не съществуват в SLES12 (напр. polkituser)
б) Прехвърляне на потребители на OS SLES11, които имат същото потребителско име като на SLES12, но са малко по-различни (напр. sshd, ntp)

while read line; do if ! grep "$line" /etc/shadow_sles11.default &> /dev/null; then echo $line; fi; done < /etc/shadow
Register:
copy /opt/apxpccp/recreate_pccp_pks.sh and /opt/apxpccc/recreate_pccc_pks.sh to the server
 
scp /opt/apxpccp/recreate_pccp_pks.sh <SERVER>:/opt/apxpccp/recreate_pccp_pks.sh
scp /opt/apxpccc/recreate_pccc_pks.sh <SERVER>:/opt/apxpccc/recreate_pccc_pks.sh
 
and run it on <SERVER>
 
/opt/apxpccc/recreate_pccc_pks.sh
/opt/apxpccp/recreate_pccp_pks.sh
