When the system boots after installation, the insf command automatically creates the proper device files for the “ctl” interfaces, including the A7173A adapter and the SCSI devices attached to it. Under certain conditions, though, the insf command does not create all of the necessary device files. For example, this can occur if you attach additional SCSI disks to an A7173A adapter that is already installed in a system that is up and running.
Example 5-1 shows part of a typical ioscan command output, as it could appear when verifying the A7173A installation (see “Verifying the Installation”):
Example 5-1 Typical ioscan Listing of SCSI Devices
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 Example 5-1, the second line of each disk entry shows the device file for that disk, in the format /dev/dsk/cxtxdx [...]. If you see a disk or other SCSI device listed without the second line, then its device files are missing.
To correct this problem, use the insf -e command to create all of the device files. Then use the ioscan command again to confirm that the device files have been created.
