How to install WAS 8.5.5 from command line

Hi Team,
I tried to install WAS 8.5.5 through putty for Linux x86_64 architecture.
I've downloaded 3 files of WAS 8.5.5 and I've done silent installation of IM 1.7.2
When I try to run install command it gives me error message. Please look into below details and help me.
./imcl -s install com.ibm.websphere.BASE.v85_8.5.5000.20130514_1044 -installationDirectory /opt/IBM/WAS8.5.5 -repositories /root/Software/WAS8.5.5/WAS_V8.5.5_1_OF_3/disk1 -acceptLicense
ERROR: The following errors were generated while installing.
ERROR: The silent installation process does not support installing packages that are contained on multiple media discs.

Hi Narasimha,
The problem is a Websphere Application Server issue, which is more appropriate to post on IBM DeveloperWorks forum
Hope this post (https://www.ibm.com/developerworks/community/forums/html/topic?id=b59aca83-73ae-4a70-960b-0c538c39a217) can fix your issue. If it doesn't help, I suggest you ask on IBM DeveloperWorks forum

You need to make some adjustments in order to run that command successfully.
1. Merge the contents of the three packages to the same folder. For example, make sure that under /root/Software/WAS8.5.5/WAS_V8.5.5_1_OF_3 you can see "disk1", "disk2" and "disk3". For general purpose of making a "single source", you can use Packaging Utility.

2. Change the -repositories parameter to
/root/Software/WAS8.5.5/WAS_V8.5.5_1_OF_3 (by removing "disk1"). This way, Installation Manager will pick up the repository.config file rather than the diskTag.inf file.
I can install WAS 8.5.5 on a Windows machine in the same fashion (using the imcl command) with such configuration.
