Hello, Only 15 partitions available per scsi disk. Why? Because of 8bit major/minor numbers for device files. One major number per controller, each controller can have 16 devices, which leaves 16 numbers for partitions, of which 1 describes the entire disk (ie /dev/sda), leaving 15. From what I have read, it seems that LVM can be used to get around this, but I don't know anything about it, sorry. There must be another way however, perhaps some one else will tell. -d -- darren kirby :: Part of the problem since 1976 :: http://badcomputer.org "...the number of UNIX installations has grown to 10, with more expected..." - Dennis Ritchie and Ken Thompson, June 1972
