DR (Disaster Recovery) server installation.

Dear Experts,

We have one server for BI PRD. We are not using it at the moment. We wish

to carry out DR (Disaster Recovery) trial on this server. Regarding thiswe have following queries :

1. Do we require separate SAP License key for this server when setup forDR (already SAP license key exists for it as BI server)

2. We will re-install BI on the same server after our DR test so whetherwe need to regenerate License key for BI or not?

3. We have two R/3 PRD servers in HACMP mode in SAN. Can we take the

backup of R/3 PRD and restore it on DR Trial Server? If yes, whether we

will face any problem for existing PRD server?

4. Whether Existing PRD and Trial DR Server will clash or hang since

these will be in the same local network and SAN

Please advise.

Regards,

Kailas Padwale.

Hi,

As per your query you have not mentiones here what is your opreting system and whcih SAP verson you are using. If any one need related to implimentaion then we keep in mind to os,sap version,database etc.

Your Question: If you want to DR of PRD then you have to get my answer.

1. Do we require separate SAP License key for this server when setup forDR (already SAP license key exists for it as BI server)

ANS= Yes you can generated from SAP Site becasue now this is BI and you want to DR but for this you have not paid any thing to SAP its free.

2. We will re-install BI on the same server after our DR test so whetherwe need to regenerate License key for BI or not?

ANS=NO becasue you have to use only PRD copy you can not run BI here otherwise how can you say this is DR server. DR Server means you can copy in existing running server, in case you running server get down then within short period you can provide the solution. After rectificaton actual server you will shift in old one.

3. We have two R/3 PRD servers in HACMP mode in SAN. Can we take the

backup of R/3 PRD and restore it on DR Trial Server? If yes, whether we

will face any problem for existing PRD server?

ANS=You can restore backup but you have to take backup only one PRD server and restore it in DR. Just chang your IP Address and rest can be same. You will not face any issue on this if you run in the same network. I will recmond if you use database in DR server itself then good for your running system will not impect.

4. Whether Existing PRD and Trial DR Server will clash or hang since

these will be in the same local network and SAN

ANS= No because you will use seprate IP address and data will be in DR server not in SAN.

In case you need more help, pls get in touch.
