it is hard to diagnose the problem without any evidence
It may be that you created only one volume on RAID and installed DSS on it?
Volume used as system medium will not be visible. Have you checked in DSS V6 hardware compatibility list if your RAID controller is supported? In DSS V6 logs you can find output of 'fdisk' command to see what is really happening with your drives.
ok well dividing the raid array from scrach into to VG did the job, this is also what was adviced in open-e forum....
big thanks to Open-E, before closing the question i have one left regarding this issue.
i have 4 Physical disks, i wanted to create the first volume as 2 giga like recommended, (each disk is about 150 GB) , problem is , that when i selected 1 or more disk for the use of the first VG, i coudnt select the availble disk space that remained on this disk (which is quite alot) to the second VG where i put all the rest of the disk in raid 5.
this caused me alot of unused spaced to be vasted.
is it possibole to allocate 1 Physical disk in to more then one VG , how do i manage to create the first VG only in 2 GIGA capacity without lossing all the remanning disk space that i wanted to alocate from this disk to the second VG which defined as raid 5 array?
