Disaster recovery using SAN replication

[Former Member]

I have posted this within a previous thread but I started a new thread to get fresh view on this from our sdn basis contributors

We are trying to setup a DR system with SAN replication.

PRD = production SID

The datafiles and log files of sap system PRD (on host1) are on SAN. The infrastructure team has set up SAN replication between primary site SAN and secondary.site SAN In the case of a DR situation, infrastructure team will attach the secondary site SAN LUNS to the DR system (host2) which already has SAP installed. Below are they steps that were done

These are steps covered till now

1) A system refresh of system PRD (host 1) to PRD on (host2) using backup/restore of the PRD database has been performed and then we ran the migration tool of SAPINST (on host 2)

2) DB team has setup SAN replication to secondary SAN at DR site. They are managing it with a SAN replication software.

3) They plan to test the DR by doing the following

a) Pause replication between the 2 SANs

b) Attach the secondary SAN to host 2

c) Map the driver letters for datafiles to be the same as entered during installation of SAP on host2 via SAPinst

4) Start SAP

Will this work ? Will the master db, msdb, model and tempdb of MSSQL server also need to be restored Any ideas on this

Thanks, Vikram
