Installing SAP systems onto servers with Windows Mount Point failing

[Mofizur]

We were performing SAP Installtion for a new Project and during the Target system installation using SYSTEM COPY method I was facing below error

Not sufficient space is available on drive.  xxx MB are required, only yyy MB are free.

SOLUTION: Provide enough space

We created eight different mount points and made sure we had enough spaces on all the mount pounts but SAPinst was still throwing the error.

How to resolve the error in SAPInst?

The error in SAPInst is cause by the SAP Installer checking the freespace on the Mount Point Root Disk and not on the individual Mounted Disks.

There are two easy solutions to this problem:

1.     Create the Database manually before starting SAPInst using the script below – SAPInst will bypass this screen and install

2.     Set the size of the Database to something very small (such as 1GB) and the installer will continue.  SQL Server Data Files will grow automatically during the installation or you can manually increase them (ensure Note 1238993 is implemented).

We followed option 2 and everything went fine.
