Moving SAP directories

[Former Member]

Hi, we plan to change our SAN storage hosting the SAP application.

We are on Windows 2003, running SAP ERP6 on Oracle 10.2.

Below is the current directory setup for SAP ERP:

RedoLog_A (Drive M)

RedoLog_B (Drive N)

ArchiveLog (Drive O)

Oracle Binary (Drive P)

SAP Binary (Drive Q)

Data (Drive R)

Above Drives are located in SAN. We will install a new SAN storage to replace existing one, what would be the best way

to move the data to new storage? Can I do this way:

1. To replace current RedoLog_A (Drive M), install a new drive say Drive Z

2. Copy all files from Drive M to Drive Z

3. Rename Drive M to another alphabet

4. Rename Drive Z to Drive M.

5. Repeat steps for other Drives

Will this work?

Hi Daren

In this case you can assign the new SAN stores to exiting server and the do the Disk Mirroring. once the mirroring synced, remove the mirroring. for this you can refer the below links

in this same we have migrated the SAN Storage from IBM 4300 to 6100

Thanks

Hi Daren,

Not only SAP but Oracle database as well as services should also be down before you proceed with the steps.

Ideally the steps should work as desired but as it is windows I could forsee some issues with system registry entries.

Best Practise is to take a full offline backup and restore it as per the drive format you needed. Recreate the control file to consider the new layout.

Hope this helps.

As long as SAP is shut down and you move/copy the files to the new drive that is going to replace the current drives; then everything should come on line without issue.
