Fita DAT DDS4 nao monta!!??

Boa tarde pessoal.

Seguinte tenho uma servidor Itautec aqui no qual estou querendo fazer backup dos seus arquivos, pois este 'e o servidor de arquivos da rede e nele roda o Slackware 10.2, ele tem um drive de fita DAT DDS4 de marca Quantum/Seagate, quando tento fazer o backup por exemplo :

tar -cv -T /home -f /dev/st0
ou
tar cvf /dev/st0 /home

Da esse erro:

tar: /dev/st0: Cannot open: No such device
tar: Error is not recoverable: exiting now

Ja tentei montar o dispositivo mas nao monta, e tb nao tem referencia ao drive DDS na fstab como podem ver abaixo.
/dev/sda1 swap swap defaults 0 0
/dev/sda2 / reiserfs defaults 1 1
/dev/sda3 /home reiserfs defaults 1 2
/dev/cdrom /mnt/cdrom auto noauto,owner,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0


O Drive de fita esta funcionando, pois tinha o win03 instalado aqui neste server e funcionava, mas
quero manter o Linux nele.

Acrecento que ele possui HD SATA e na instalacao do Slack usei o kernel SATA.i, portanto nao sei se tem suporte a SCSI.

Por favor alguem tem ideia do que pode ser ??
Desde ja agradeco.

Cara, roda um dmesg e verifica se tem alguma referencia ao tape. Caso não exista (e pelo que eu entendi ela é ligada pelo scsi) procure saber se existe no dmesg algo referente ao SCSI. Quando ao sata.i, em geral ele tem suporte básico a scsi, ou seja, partes do protocolo, pq é o mesmo que é usado para acesso a dispositivos sata.
qq coisa é só perguntar.

Nao achei nenhuma referencia ao drive DAT na saida do dmesg, mas por favor se puder dar uma olhada agradeco ...

Olha, qual é a versão do kernel q vc tá usando? pode ser que seja interessante usar um kernel da série 2.6, de preferência compilado por vc mesmo para tentar saber como a controladora scsi é identificada. Sugiro que vc tente dar boot na máquina com o slax, que vem com um kernel 2.6 para verificar qual é o módulo necessário (rodando novamente o dmesg e lspci ) já que vc está usando o kernel 2.4.31 padrão. rode o slax e verifique.

Blz .. vou baixar o slax e ver no que da ..
Posto aqui depois...
Bom final de semana.
[]'s

Como sugerido usei o Slax com kernel 2.6 o mesmo tb nao identificou a placa ..tentei tb com o Debia Sarge e tb nao funciona.. A placa SCSI e uma LSI Logic 20320R.
Se alguem souber de uma maneira de faze-la funcionar fico muito grato, e acredito que outros tb ficaram, pois essa plaquina esta me dando uma dor de cabeca ..
[]'s a todos.

Cara, ele nao ta em /dev/dat?
Tenta definir o driver pra ele usar: setenv TAPE /dev/dat
Depois mounta.

Em adicao, quais comandos voce ta usando pra o uso dela?

Bom fucando no menuconfig para reconfigurar o kernel achei os modulos que nao sei o motivo nao veem listados no rc.modules do Slackware, que sao da "Fusion-MPT".
Diante disto adicionei as linhas no rc.modules.

/sbin/modprobe mptbase
/sbin/modprobe isense
/sbin/modprobe mptscsih

Blz rebootei e ele achou a placa como podem ver abaixo na saida do dmesg.

-----------------
Somente que nao foi vinculado a um /dev/qualquer ..

Segundo uma instrucao que peguei no site do fabricante .. :
All Fibre Channel target devices should be detected and mapped to linux
SCSI devices, /dev/sd{a,b,c,...} when the mptscsih module is loaded.

Mas nao foi .. ou seja ainda nao da pra monta-lo...

mount /dev/sdb
mount: can't find /dev/sdb in /etc/fstab or /etc/mtab
mount /dev/sdc
mount: can't find /dev/sdc in /etc/fstab or /etc/mtab
mount /dev/st0
mount: can't find /dev/st0 in /etc/fstab or /etc/mtab

Como eu descubro em onde esta ???
Desde ja agradeco..

Amigo

Você não vai conseguir montar uma unidade de fita, pois elas são dispositivos sequenciais.

Para testar se está funcionando, primeiro identifique o device que ela está, se estiver, muito provavelmente será em /devst0, mas pelo jeito esse é o seu problema, saber se está vinculada ou não.

Tente carregar os módulos st e scsi_mod

Deposi teste com o comando mt -f /dev/st0 status

o st0 pode ser diferente :)

o resultado deve ser algo como:

intranet:~ # mt -f /dev/st0 status
drive type = Generic SCSI-2 tape
drive status = 1191182336
sense key error = 0
residue count = 0
file number = 1
block number = -1
Tape block size 0 bytes. Density code 0x47 (unknown).
Soft error count since last status=0
General status bits on (9010000):
EOD ONLINE IM_REP_EN
intranet:~ #

Espero que ajude

Falowwwwwwwwwwww

Blz galera.

Obrigado pela ajuda .. o driver esta funcionando no /dev/st0 ..
