Re: [SLE] Help with external Tape unit [SOLVED]

Thanks Ciro and Sandy. The solution was to add these lines to /etc/init.d/boot.local: for x in /proc/driver/cciss/cciss[0-9]* do echo "engage scsi" > $x done after restarting the system detected the tape unit with these messages: st: Version 20040403, fixed bufsize 32768, s/g segs 256 BIOS EDD facility v0.16 2004-Jun-25, 3 devices found ERROR: SCSI host `cciss' has no error handling ERROR: This is not a safe way to run your SCSI host ERROR: The error handling must be added to this driver [<f884f749>] scsi_host_alloc+0x2c9/0x2f0 [scsi_mod] [<c0162c0c>] do_truncate+0x5c/0xa0 [<f8870c93>] cciss_scsi_detect+0x13/0x90 [cciss] [<f8871d3e>] cciss_engage_scsi+0x5e/0xa0 [cciss] [<c01f9ac4>] copy_from_user+0x34/0x70 [<f8872195>] cciss_proc_write+0x75/0xa0 [cciss] [<c0156736>] vma_link+0x66/0x100 [<c01573b6>] __do_mmap_pgoff+0x466/0x770 [<c019861f>] proc_file_write+0x2f/0x40 [<c0164d82>] vfs_write+0xc2/0x140 [<c0164eb1>] sys_write+0x41/0x70 [<c0107ffd>] sysenter_past_esp+0x52/0x71 scsi0 : cciss Vendor: HP Model: Ultrium 2-SCSI Rev: F48D Type: Sequential-Access ANSI SCSI revision: 03 Attached scsi tape st0 at scsi0, channel 0, id 0, lun 0 st0: try direct i/o: yes (alignment 512 B), max page reachable by HBA 4294967295 Attached scsi generic sg0 at scsi0, channel 0, id 0, lun 0, type 1 I've some doubts about the above messages. Does these missing error handlings to cciss's driver will affect the backups i'll make? Is it correct to assume the tape is /dev/st0 instead of /dev/sg0 ? Wich is the speed of this tape unit ? I want to backup the all system for recovering in case of hard disk failure, what do you advise me, tar, dump or something else ? Best regards Oxiel El Mar 27 Sep 2005 00:31, Ciro Iriarte escribió:

Hello everybody.

I've installed SuSE 9.2 Pro (x86) (2.6.8-24.16-bigsmp) to an HP-Proliant DL360 with an array controller:

lspci -v says:

0000:0b:04.0 RAID bus controller: Compaq Computer Corporation Smart Array 64xx (rev 01) Subsystem: Compaq Computer Corporation Smart Array 6400

hwscan detects this:

cB5L.gwvXxx1Amj4: (cfg=yes, avail=yes, need=no, active=unknown) storage Compaq Smart Array 6400

Connected to it is an external tape unit: HP StorageWorks Ultrium 460

While booting the server the card and the tape unit gets recognized:

Slot 2 HP Smart Array 6400 Controller (192 MB, v2.34) 1 Logical Drives Tape or CDROM Drive(s) Detected SCSI Port 2: SCSI ID 3

But when loading the kernel, there does not appear messages seeing the tape unit, the st module gets loaded but without any dependent device. If i issue:

mt -f /dev/sr0 status

an error occurs.

What can i do? , rh7-9 detect this device witouth adding anything.

Is there something i forgot to do in order to make SuSE recognize the tape?

Any suggestion is wellcomed.

Regards

Oxiel

That question has been asked at least twice on the list before, please, search the archives before asking something.
