Serious issue dumping a 300Gb database on ASE 15.7 Esd 4.2

Hi,

We are facing a serious issue trying to dump a 300gb database :

we tried several methods and all of them leaded the server to stop responding at all

simple dump , dump with compression=1,dump with compression=100, dump with 5 stripes.

Currently I got no way out to quiesce/rcp devices/mount the database on the target server

Sybase ASE 15.7 Esd 4.2 on Solaris 10 on Sun M3000 disks arrays SCSI on zfs

We are thinking to move the database to 2 new internal sas HD's to see if it is a problem between Sybase and Zfs.
