Description Rob van der Heij 2003-08-27 09:00:02 UTC
Description of problem:
The installer attempts to add all devices to the Linux dasd driver and even
decides to format the disk without interaction with the user. There does not
seem to be a way to restrict the range of dasd devices the installer picks

Version-Release number of selected component (if applicable):
initrd dated Jul 22 00:43
netstg2.img  Jul 22 00:44

How reproducible:
Installing in a virtual machine the console is filled with lots of msgs like
dasd: <devno 000e> Add lowmem page :...
dasd: device range 019b-019b: device 019b already in a range 

Additional info:
I believe earlier versions used the DASD= option in the parameter
file that is used for the first part of the configuration.

Comment 1 Karsten Hopp 2003-08-27 13:43:44 UTC
I've tested this with our latest images on s390 and s390x with a DASD=XXX parameter in 
the .parm file. Only the defined dasds were probed and added to /proc/dasd/devices. 
Did you test this in hercules ? We could reproduce this in hercules, but not on real hardware. 
Or did you leave out the DASD= parameter ? We accidently left it out in our documentation but 
added it in the meantime. 
Can you please elaborate on 'decides to format the disk without interaction with the user' ? 
Which DASD has been reformatted ? Has it been a CMS disk or maybe a LDL formatted disk ?

console log of the install

The log shows the DASD=200-207 and further down you see the installer tamper
with devices outside that range (not even disks).

Comment 3 Rob van der Heij 2003-08-27 14:05:18 UTC
The log file shows the installer tampering with devices outside that list. Also,
a nother disk in the specified range but not formatted was not picked up.

Re: unsolicited formatting
This was a recycled virtual machine, so the disk was probably CDL format and
most likely had a ReiserFS filesystem on it. If really helpful I can make sure
to try with that combination next time I run the install. 

Comment 4 Karsten Hopp 2003-08-27 14:47:08 UTC
easy fix: reorder your .parm file so that DASD= isn't the first parameter in the .parm file. 
I've already committed the real fix to CVS.
