Cisco ISE Install Issues

[Chris Terry]

I’m trying to reimage a SNS appliance with Cisco ISE. I’m using a bootable USB. 

When I boot from the USB and choose install it will kick off the install. During the install it mentions sda was not unmounted properly. It keeps going and then gives a message about dracut-initqueue 668 warning could not boot and then it’s goes into a emergency GNU bash shell with the prompt dracut:/#

it seems like an issue with installing to the drive. 

Is there a way to fix it? Is there a modification to the grub file that needs to be done? A set of commands to be ran in the GNU bash shell or efi shell? Something that can done in the LSI Software RAID set up utility?

The easiest way around this might be to just mount the ISO as a "dvd" via the CIMC html5 interface. If that's not an option then another thread had suggested this error can also be related to not booting with uefi enabled. 

There are instructions for creating a bootable USB for ISE installation, I'm asusming you already found it and have followed the instructions it provided.

It does look like it's in Legacy boot instead of UEFI. Do you have a link to the other thread?

No matter what I did I was unable to install it via USB. I had to get access to the CIMC GUI and mount the ISO as you mentioned. It was on an older version so it wasn't a possibility at first.

There is a flaw with the USB instructions and you need to set it to sdb1. I know I ran into this on our 3595s.

replace ks=cdrom:/ks.cfg with ks=hd:sdb1:/ks.cfg

But for me, the best device is an iodd. The device mounts an ISO as a cdrom, no editing etc, ISE sees it as a CD and works wonders. But as you are probably down on that machine, try the sdb as that is what worked for us.
