Dear Mr. Heinz Mauelshagen : I'm using a IBM xseries server with the LSI Logic MegaRAID card, with a RAID-1 (two disks) and I have booted it with the cdlive sytemrescuecd ver. 2.0.0 I have the problem with the dmraid since I canÂt do the dmraid -ay command. When I use it I get these messages: RAID set "lsi_cefcidgfeea" already active RAID set "lsi_cefcidgfeea" was not activated ERROR: opening "/dev/mapper/lsi_cefcidgfeea" At this point if I try to list the directory /dev/mapper, the result is like this one: ls -l /dev/mapper rwxr-xr-x 2 root root 60 Apr 26 15:06 . rwxr-xr-x 15 root root 60 Apr 26 16:05 .. rw------- 1 root root 60 Apr 26 15:04 control And there is any files more. If I typed: dmsetup -mkdnodes, the result is: Please specify both major number and minor number. Couldn't process commend line. Finally the /var/log/messages (at tail) we can read a lot of lines like this one: kernel: [ 3721.490147 ] devcie-mapper: ioctl: device doesn't appear to be in the dev hash table. I don't know what another thing I can do. Best regards Luis MartÃn DÃaz AutomatizaciÃn de Estaciones. Sistemas de InformaciÃn Cepsa EE.SS. Avda.
