Fita DAT DDS4 nao monta!!??

[Chacall]

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

[Chacall]

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.

[Fernando]

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?

[Chacall]

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..

[MarcioRM]

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

[Chacall]

Blz galera.

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