Can anyone tell me how to verify that the proper drivers are loaded on a sun box ... I'm trying to do a new TSM Server install without much help from my Sun Admins and I have next ot no Solaris experience. I've defined the library and now I'm trying to define the drives. I've read the doc about doing the define drive. This is what the devices look like in my /dev/rmt directory lrwxrwxrwx 1 root other 57 Nov 10 14:07 1stcn -> ../../devices/sbu s@5d,0/QLGC,isp@0,10000/IBMtape@0,0:stcn lrwxrwxrwx 1 root other 57 Nov 10 14:07 2stcn -> ../../devices/sbu s@5d,0/QLGC,isp@0,10000/IBMtape@2,0:stcn I issue the following command: DEFINE DRIVE 3494LIB rmt1 DEVICE=/dev/rmt/1stcn ONLINE=YES and I get the following response ANR8420E DEFINE DRIVE: An I/O error occurred while accessing drive RMT1 I've checked that the devices are physically attached properly. Am I missing something else?
