I guess it's not recognized. In /proc/scsi/scsi there is only one 'Sequential-Access' device (nst0), but there isn't the second tape. If I execute dmesg it seems that the system only detects one of the two tapes. On the back of the external tape drive there is a button to change the IRQ number. Now there is a number 6. Here I attach my /proc/scsi/scsi file and the output of dmesg: ----------------8<------------------------8<----------------------8<------------------------8<---------------------- Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: IBM Model: DGHS09U Rev: 0370 Type: Direct-Access ANSI SCSI revision: 03 Host: scsi0 Channel: 00 Id: 01 Lun: 00 Vendor: IBM Model: DGHS Rev: 0370 Type: Direct-Access ANSI SCSI revision: 03 Host: scsi0 Channel: 00 Id: 02 Lun: 00 Vendor: ARCHIVE Model: IBM-STD224000N!D Rev: 726B Type: Sequential-Access ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 03 Lun: 00 Vendor: IBM Model: CDRM00203 !K Rev: 1_00 Type: CD-ROM ANSI SCSI revision: 02 ----------------8<------------------------8<----------------------8<------------------------8<---------------------- device tree used 33120 bytes No RTAS service called display-character No RTAS service called display-character No RTAS service called display-character No RTAS service called display-character No RTAS service called display-character No RTAS service called display-character No RTAS service called display-character No RTAS service called display-character No RTAS service called display-character No RTAS service called display-character No RTAS service called display-character No RTAS service called display-character No RTAS service called display-character No RTAS service called display-character No RTAS service called display-character No RTAS service called display-character No RTAS service called display-character No RTAS service called display-character Total memory = 512MB; using 2048kB for hash table (at c0600000) Linux version 2.2.16 (root@CHRP.suse.de) (gcc version 2.95.3 19991030 (prerelease/franzo/20000625)) #1 Thu Oct 5 01:30:44 GMT 2000 Boot arguments: root=/dev/sda3 OF CTG0 OF CTG0 Warning: no mac-io found PCI buses 0..1 controlled by pci at 80000000 RTAS Event Scan Rate: 1 (2999 jiffies) OpenPIC Version 1.0 (4 CPUs and 16 IRQ sources) at f8ec0000 OpenPIC timer frequency is not set time_init: decrementer frequency = 1246848720/60 Console: colour dummy device 80x25 Calibrating delay loop... 249.04 BogoMIPS Memory: 513724k available (1688k kernel code, 8600k data, 168k init) [c0000000,e0000000] Dentry hash table entries: 65536 (order 7, 512k) Buffer cache hash table entries: 524288 (order 9, 2048k) Page cache hash table entries: 131072 (order 7, 512k) VFS: Diskquotas version dquot_6.4.0 initialized POSIX conformance testing by UNIFIX PCI: Probing PCI hardware Warning: no ADB interface detected pmac nvram is core99: 0 Don't know how to access NVRAM with 4 addresses Linux NET4.0 for Linux 2.2 Based upon Swansea University Computer Society NET3.039 NET4: Unix domain sockets 1.0 for Linux NET4.0.

Is is listed there? Does the entry exist in /dev? Also "dmesg" should give you some clues too. nstx is the "non-rewinding" device entry. The devices should also exist under "stx", where x = 0,1,2 etc. Do the 2 devices have unique SCSI ID's?

Hi. I've got SuSE 7.0 for PPC installed on my RS/6000 and I have a problem with my second tape drive.
I'm not very skilled on Linux and I don't know how to install a new tape, but with the SuSE installation it is automaticaly.
I can obtain information from the first tape by typing:
mt -t /dev/nst0 status
The second tape ( /dev/nst1) is an external scsi tape and when I try to get the tape status...
mt -t /dev/nst1 status
I get the following error:
mt: /dev/nst1: Device not configured
I don't know how to configure the device. I don't know if it is not configured because it doesn't work property or because I do have to configure it.
Can anybody give me any advice or any website where I can get some help?
Thanks in advance Jorge.
