It will all be down to the filesystem type.  NTFS can create big, mostly 
empty files quickly.

[ADSM-L] define volume takes a long time in AIX




Caterpillar: Confidential Green Retain Until: 01/04/2010 



Hi,
TSM volumes can be defined instantly in TSM server for Windows but take
several minutes in TSM for AIX. What could be the reason?
- AIX version is 5.3 with latest patch on both platforms
- volume is defined on a single internal physical disk (no SAN, no RAID)
- windows disk is a 500GB SATA, AIX disk is a 36GB 10K rpm SCSI drive
- windows can define a 100GB volume in one second, but AIX defines a 30GB
one in some minutes!

Thanks,
Mehdi
