Following the instructions at https://support.f5.com/csp/article/K13117 will occasionally fail on iSeries platforms, with the system being unable to find the installation media. If this happens, running the following command will fail. image2disk --instslot=HD1.1 --setdefault --nosaveconfig


The /dev/cdrom softlink points to the virtual CD-ROM drive in iSeries platforms instead of the physical USB DVD-ROM drive. This prevents image2disk from automatically finding the installation media.


This can occur on iSeries platforms while performing a clean installation.


After the failure, while in MOS, determine USB CDROM device name, mount it, and tell image2disk specifically where it is: bash (try 'info') / > dmesg | grep "sr0\|sr1" sr0: scsi3-mmc drive: 62x/62x writer dvd-ram cd/rw xa/form2 cdda tray <-- cdrom name sr 6:0:0:0: Attached scsi CD-ROM sr0 sr1: scsi-1 drive sr 7:0:0:0: Attached scsi CD-ROM sr1 bash (try 'info') / > mount -r -t iso9660 /dev/srX /cdserver bash (try 'info') / > image2disk --instslot=HD1.1 --nosaveconfig /cdserver In the mount command, replace "/dev/srX" with whichever device is the physical drive.
