information about installing and conguring the IBM tape drive. Also, “Installation and Conguration
Instructions” describes the smit and cfgmgr commands. Figure 75 on page 226 shows an example of
software and hardware paths that are used in the following tests. The gure illustrates unique initiator
addresses for a conguration with more than one initiator that shares a Fibre Channel.
Note: Port 1 of a 3592 tape drive is connected to two hosts. Host drivers are congured so that one
initiator is at ID address 7 and one initiator is at ID address 6. Tape special le names on each host are
independent and might be different.

Inquiry command
Note: This section depicts a mix of SCSI and bre inquiry sequences of events for an inquiry of the tape
drives.
Inquiry sequence
1. To check installed tape devices, type the lsdev -Cc tape command. From the listing of devices,
remember the ones that you are going to test. In the following example, bre devices rmt0 and rmt1
are available, which indicates they can communicate with host. The bre address is not shown with
this command.
The SCSI devices rmt2 and rmt3 are available and at port addresses (2,0) and (1,0). These addresses
are SCSI addresses 2 and 1.
