The machine is a Dell Poweredge 2950, and includes a PERC/5i card and six disks. As I'm using ZFS I don't need the array functionality at all, and it's actually causing problems if I just create six logical volumes. I have seen that there is a "mfip" device that works as a passthough, so I have tried to destroy the six logical volumes I had created. Using the GENERIC kernel I had installed with the distribution (which includes the mfi driver) I've loaded the mfip module from the boot command line. After booting, a "camcontrol devlist" shows the six disks, but only as "passthrough devices". How can I make them be attached as disks? I've tried to use the "da" driver (using device.hints) but I have been unsuccessful. Unfortunately Dell doesn't sell a non-array option for this machine supporting 6 disks. The non-array option, which I think is based on SATA, supports only four. Any ideas? The PERC/5i plain sucks for this purpose. I tried to unplug one of the disks (remember that I have a separate logical volume for each disk) and the card renumbered the rest of the logical disks, making the ZFS pool unusable until I rebooted, erased the PERC config, and recreated the six logical volumes. Thank you very much, Borja. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (Darwin) iD8DBQFHJ1i+ULpVo4XWgJ8RAnxfAKCfLueqEI8ow79d6lIt2RJepKuo6wCgwrCs pp9zXb9QAtUnHo4kyn70WE8= =gydj -----END PGP SIGNATURE-----
