服务器是富士通TX140与控制器Symbios逻辑SAS1064ET PCI-Express Fusion-MPT SAS磁带+硬件是新的。
对于我的SAS和SCSI连接的磁带设备，当我使用MPT Fusion / LSI控制器时，通常会看到以下模块：
[root@Lance ~]# lsmod | grep mpt mptctl 31976 4 mptspi 17051 0 mptscsih 36828 1 mptspi mptbase 94037 3 mptctl,mptspi,mptscsih scsi_transport_spi 26151 1 mptspi
要么…
[root@Doper ~]# lsmod | grep mpt mptctl 74953 4 mptscsih 2625 0 mptsas 26977 1 mptscsih mptspi 13521 1 mptscsih mptscsi 50641 2 mptsas,mptspi mptbase 78625 4 mptctl,mptsas,mptspi,mptscsi scsi_mod 146193 9 sg,st,libata,cciss,mptsas,mptspi,mptscsi,usb_storage,sd_mod
看看你的设置，看看你是否有相同的模块加载。
