Set up devices

iXOS-JUKEMAN 2.2 User Manual Pre.12/97 51

AIX uses a multiplex driver: You can use the devices but not see them. If

you issue the following command:

ls -l /dev/iXOS_SCSI?

the output should look like this:

lrwxrwxrwx 1 root system 13 Oct 22 14:22

/dev/iXOS_SCSI0-> genscsi/scsi0

lrwxrwxrwx 1 root system 13 Oct 22 14:22

/dev/iXOS_SCSI1 -> genscsi/scsi1

This shows that the files are in fact symbolic links to our generic SCSI

driver. You can use the csh expansion mechanism ‘{...}’ to list the device

paths created by the driver. For example the following command:

ls /dev/iXOS_SCSI{0,1}/{0,1},{0,1}

gives the following output:

/dev/iXOS_SCSI0/0,0 not found (or does not exist)

/dev/iXOS_SCSI0/1,0 not found

/dev/iXOS_SCSI0/0,1

/dev/iXOS_SCSI0/1,1

/dev/iXOS_SCSI1/0,0

/dev/iXOS_SCSI1/0,1

/dmv/iXOS_SCSI1/1,0

/dev/iXOS_SCSI1/1,1

This shows that on the first SCSI bus (/dev/iXOS_SCSI0) on IDs 0 and

1 there are two hard disks or other SCSI devices which cannot be ac-

cessed by the operating system. The access restriction is on LUN 0 only,

whereas LUN 1 normally replies to the command. Our inquiry command

prints the following:

inquiry /dev/iXOS_SCSI0/0,{0,1}

/dev/iXOS_SCSI0/0,0: Bad file number

0000000 /dev/iXOS_SCSI0/0,1 is IBM's unknown "DORS-3"

The operating system is not as restrictive for CD drives and jukeboxes:

inquiry /dev/iXOS_SCSI0/6,0

0000000 /dev/iXOS_SCSI0/6,0 is IBM's CD-drive

"CDRM00203"
