Hello Todd,
thanks for your respond.
Now it looks like that the RAID controller is damaged because the new disk goes to BAD after one hour. I will receive the sparepart on Friday.
In the worst case, if I cannot repair the RAID what is the procedure:
Setup Open-E
Setup Storage Replication and wait until finished
then Setup iSCSI Failover ?
At the moment I hope I can save the RAID... We will replace the controller, then the damage disk and try to rebuild it.
bye Manuel
