IBM LTO (Win<strong>do</strong>ws 2000 e Win<strong>do</strong>ws Server 2003) emitirá um coman<strong>do</strong> SCSI<br />

Reserve <strong>para</strong> os dispositivos <strong>de</strong> fitas quan<strong>do</strong> o servi<strong>do</strong>r principal <strong>do</strong> <strong>CA</strong><br />

<strong>ARCserve</strong> <strong>Backup</strong> abrir os dispositivos. Não é um problema <strong>para</strong> o servi<strong>do</strong>r<br />

principal, mas quan<strong>do</strong> o servi<strong>do</strong>r integrante conecta<strong>do</strong> à SAN tentar acessar<br />

esses dispositivos <strong>de</strong> fitas ele falhará e os dispositivos não serão utilizáveis a<br />

partir <strong>de</strong>sse servi<strong>do</strong>r.<br />

Solução:<br />

Falha nas tarefas <strong>de</strong> backup<br />

nome <strong>de</strong> chave que seja igual ao nome <strong>de</strong> arquivo <strong>do</strong> driver <strong>de</strong> fita IBM.<br />

Por exemplo, se o nome <strong>de</strong> arquivo <strong>do</strong> driver <strong>de</strong> fita IBM for ibmtp2k3.sys,<br />

o nome <strong>de</strong> chave será ibmtp2k3.<br />

Selecione a chave, adicione um valor DWORD <strong>de</strong>nomina<strong>do</strong><br />
