Externes SCSI-RAID an Adaptec-HBA
Liebe Gemeinde,
an einem Server mit via PCI-Express dazugestecktem
Adaptec ASC-29320ALP ist ein easyRAID-Speichersystem angeschlossen. Auf
diesem habe ich ein etwas voluminöseres RAID6 eingerichtet, das in zwei
Slices unterteilt ist, die via SCSI an den Server "herausgereicht"
werden sollen. Was allerdings nicht klappt, ist der Zugriff darauf:
# gdisk /dev/sdb
GPT fdisk (gdisk) version 0.8.5
Problem opening /dev/sdb for reading! Error is 6.
# ls -l /dev/sdb
brw-rw---T 1 root disk 8, 16 Mar 19 10:36 /dev/sdb
Dasselbe Problem besteht mit /dev/sdc.
Auf dem Server werkelt ein aktuelles Wheezy:
# uname -a
Linux HOSTNAME 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1+deb7u2 x86_64 GNU/Linux
Nachfolgend findet Ihr den Output von "dmesg | grep -i scsi". Zu
beachten ist, dass neben dem SCSI-Controller noch ein
3ware-SATA-RAID-Controller in der Maschine steckt, der aber tadellos
funktioniert.

Seltsam erscheint mir die Meldung "At time of recovery, card was not
paused", aber mir sind mittlerweile die sinnvoll erscheinenden
Kombinationen von Suchbegriffen ausgegangen.
Wenn ich im dmesg-Output nach "sd*" greppe, gibt es folgende Treffer
(/dev/sda ist das 3ware-RAID):

Hat jemand einen Hinweis, in welche Richtung ich bohren sollte? Gerne
liefere ich noch weitere Informationen nach, wenn nötig.
