This is a golden command in Unix/Linux :
'find / -name tar' this will recursively search the entire system from '/' looking for 'tar'. You can substitute 'tar' with other expressions, like '\*file' ( you must escape the * with \ in opening the expression).
Regarding CDROM:
The easiest way to do anything is HP-UX is with SAM, whether in X Windows or terminal mode ( type 'sam' at command line). You can do almost everything listed here with it. Like list devices, etc.
HP-UX names the device file with the a weird syntax that is not immediately human readable, but it does make sense. Even then it does not tell you what type of the device the dev file is:
Here is a quick lowdown on a device files:
example 'c2t0d1' stands for
c2 = controller 2
t0 = scsi id 0
d1 = device number 1
"lssf c2t0d1" will provide even more info
this basically can tell you what the device file actually hooks up to now. how to tell what it is:
The easiest way, I can't think of another way, is to use "ioscan"
The following command will yield the device info on 'claimed' devices and usually a description that will tell you what it is:
'ioscan -fun' lists all devices
'ioscan -funC disk' will yield only disk device info; here's my output:

The last line is what you want, I think. Remember this is demostrative only. Your system will undoubtebly be totally different. I can tell you CD-ROM devices should be in /dev/rdsk so worst case scenario you can try to mount them one by one.
