Physikalisch ein Laufwerk aber lsscsi zeigt mehrere ...

ZenRoe

Cracks, ich benutze SuSE Version 10.1. Ich habe kürzlich eine SCSI Karte von Adaptec (39320A) montiert und am anderen Ende eine Tape Library (Sun SL24) mit einem Laufwerk und 24 slots montiert. Dem Laufwerk habe ich fix die SCSI ID 7 zugeordnet. Und ... alles läuft ausgezeichnet aber ...

Auf Seite Linux ändert sich erstaunlicherweise die Device Addresse. Mal ist es /dev/st7 und plötzlich /dev/st9 Ich habe noch kein pattern gefunden der einen Hinweis auf etwas geben könnte. Ich vermute, es hat irgendwie mit den Slots zu tun. Wenn ich ein lsscsi mache sehe ich folgendes:

[2:0:0:0] disk ATA ST3160812AS J /dev/sda
[2:1:1:0] disk ATA WDC WD7500AAKS-0 4G30 /dev/sdb

[3:0:15:1] mediumx HP MSL G3 Series C.30 -

Eigentlich würde ich hier zwei Einträge für die beiden Disks sowie einen Eintrag für das vorhandene Laufwerk erwarten. Brisanter Fact: Das Licht am SCSI Terminator leuchtet NICHT..

Die Library selber sieht gut aus:

mtx -f /dev/sg5 status
Storage Changer /dev/sg5:1 Drives, 24 Slots ( 0 Import/Export )
Data Transfer Element 0:Full (Storage Element 9 Loaded)
Storage Element 1:Full
Storage Element 2:Full
Storage Element 3:Full
Storage Element 4:Full
Storage Element 5:Full
Storage Element 6:Full
Storage Element 7:Full

Ehm.... eine Nachhilfe in Sachen SCSI auf SuSE Linux wäre hochwillkommen. Besten Dank !

spoensche

versuch mal die erste mögliche scsi id für die tape library zu verwenden, statt eine aus der mitte bzw. am ende. ggf. musst du evtl. noch was an den bios einstellungen deiner scsi karte ändern.

das wäre das, wo ich jetzt ansetzen würde.

Hi

Was mich vorher mal interessieren würde, wäre folgende Ausgabe als root aus der Konsole.

Code: 
hwinfo  --tape

...

Sieht aus als ob ich eine enorme Menge Tapes habe ....

Danke und Gruss !

whois

Puh sieht so aus.
Versuch mal das umzusetzen was spoensche geschrieben hat.
Das ist der richtige Ansatzpunkt. :wink:

1. nicht die SCSI-ID 7 für ein Laufwerk verwenden, in 99% der Fälle ist das die ID vom Kontroller und per default auch schon so eingerichtet.
Für Laufwerke 0 bis 6 und 8 bis 15 verwenden. Möglichst immer mit Null beginnen und um eines erhöhen. Laufwerke die nicht ständig angeschlossen sind also Zb ein Scanner oder temporär angeschlossenes Tape bekommt immer die letzte.
"zB Platte1= 0 ; Platte2= 1 LTO=3"

2. in den Einstellungen vom Kontroller die mherfachen LUN's deaktivieren, also nur LUN #0 suchen lassen nicht 0 bis 16 oder gar noch mehr.

EDIT zu 2: sieht so aus das deine Library auf LUN1 konfiguriert ist, also LUN 0 und 1 brauchst du schon. aber weg von ID 7 die gehört den Kontroller.

Tag allerseits,

Danke für die hilfreichen Antworten. Ich habe SCSI ID nun auf 0 gesetzt und anschliessend folgendes abgesetzt:

rescan-scsi-bus.sh -w -r

Und jetzt herrscht doch absolute Ordnung im Linux Gebälke.

Danke und Gruss !
