You can use 'dd' (as example):

dd if=/dev/zero of=/file/to/be/written bs=<blocksize> size=2048000000

This is, however, not reflecting a SAP load since it writes to the files sequentially whereas SAP reads more or less random blocks. Better use bonnie++ (http://www.coker.com.au/bonnie+/) where you can play with different options. You can get it for HP-UX at http://hpux.connect.org.uk/hppd/hpux/Sysadmin/bonnie+-1.03e/

Hello

Additionally I would like to test creation on remote host and copy to target host (with something like scp * root@oktal/var/tmp/Media)

Thx in advance
