Good suggestion, Jack, I have a nasty thought that the two 3ware 7500 cards are 64bit PCI cards so they have to sit where they are - only 2 64-bit slots on the motherboard.

The ordering of sda, sdb, etc is determined (usually!) by the order in which the disks are seen by the host. This is often governed by SCSI ID in the case of a single bus, but you've got two buses. What I've done before is put the new card so that it's seen "after" the existing one. In your case, assuming these are both PCI cards, you can probably try swapping the cards round. jack -- Jack Challen Technical Consultant, OCSL. http://www.ocsl.co.uk/ -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
