    What is the largest LUN size that AIX 5.3 can handle? We are looking at setting up 10Tbs for a back up scenario. We would like to use 1Tb LUNS, possible 2 5Tb LUNS from an EMC Sym. for this. I can't find anything that gives me a definite answer.

    Thanks!

    interesting.

    There is some IBM info about AIX volume sizes in an SVC environment:
    http://publib.boulder.ibm.com/infocenter/svcic/v3r1m0/topic/com.ibm.storage.svc.console.doc/svc_aixprob_1dcv18.html
    might be applicable to non-SVC environments as well.

    Hi

    Why use such big LUN sizes ? Depending on you how your backups will be taken you might end up wasting space when backing up small files.

    I would use LUN sizes of up to 128GB.

    Hope this helps
