hello,


i got some problem with scsi disc mapping. i got a sun sdoredge 6320 (fc) and a fedora core box as nfs server.
to maximize performance i made 400 gb discs at each disk shelf.

so i got 4 discs with 400gb each.

   Type:   Direct-Access                    ANSI SCSI revision: 03

   Type:   Direct-Access                    ANSI SCSI revision: 03


problem is that, lun 11 is on this machine, too and we would like to remove this disc from this machine. fedora (redhat) now moves my sdh to sdg

and that should not happen. how can i say that 0:0:14 is always sdh?

thanks for replies
