Creating Missing Device Files
When the system boots after installation, the insf command creates the
proper device files for the “ctl” interfaces (which are usually adapters)
and the SCSI devices attached to the A6829A adapter. Sometimes,
though, it does not create all of the needed device files. (One situation
where this happens is when you attach SCSI disks to the adapter after
the system boots [and the adapter is already installed in the system].)
The following is an example of what the output of the ioscan command
might look like when you issue it to verify the A6829A installation (see
“Verifying Installation” on page 74):

In the ioscan output above, the second line shows the disks’ device files
(/dev/... [shown in bold in the example above, for highlighting
purposes]). If you see a disk (or other SCSI devices) listed without the
second line, that means you are missing that device’s device files. To fix
the problem, issue the insf -e command, which creates all of the device
files.
