Is this message important? (The bt742a.c driver appears to not issue a message for a busy status.) From the Exabyte EXB-8200 User's Manual: "Busy status indicates the EXB-8200 is in the busy state. The EXB-8200 is in a busy state when it is performing an internal operation that prevents it from accepting another command until the operation is complete. The EXB-8200 returns Busy status for a command request until the busy state is released. After the busy state is released, the initiator must reissue the command to the EXB-8200. When the busy state is released, selection operation and commands can be executed normally." >From this, it sounds to me that this is a rather normal condition and that the driver should simply reissue the command (periodically) until successful. Is this true of other devices as well? Comments? -- Bob Willcox bob@obiwan.pmr.com (or obiwan%bob@uunet.uu.net) Austin, TX
