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 A6828A 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
A6828A installation (see “Verifying Installation”):
disk 10 0/0/1/0/1.0.0 sdisk CLAIMED DEVICE SEAGATE ST39103LC
/dev/dsk/c1t0d0 /dev/rdsk/c1t0d0
disk 11 0/0/1/0/1.2.0 sdisk CLAIMED DEVICE SEAGATE ST39103LC
/dev/dsk/c1t2d0 /dev/rdsk/c1t2d0
disk 45 0/2/1/0/1.8.0 sdisk CLAIMED DEVICE HP 18.2GST318404LC
/dev/dsk/c9t8d0 /dev/rdsk/c9t8d0
disk 46 0/2/1/0/1.10.0 sdisk CLAIMED DEVICE HP 18.2GST318404LC
/dev/dsk/c9t10d0 /dev/rdsk/c9t10d0
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.
