Description of problem:

First installation phase, request for DASD range:
input: "DASD=none" as described in manual results in "Incorrect format for lower bound ..." message
-> documentation error, input should be "none" for interactive input.

Thorsten Diehl <thorsten.diehl.com> -
Red Hat Enterprise Linux Installation Guide says at the end of chapter 19.6:

Note

The installer requires the definition of a DASD. If a SCSI-only installation is desired, enter a
DASD=none parameter interactively in installation phase 1 or written into the parameter or CMS
configuration file. This will satisfy the requirement for a defined DASD parameter, while resulting
in a SCSI-only environment.
=Comment: #7=================================================
HEMALI G. TENGSHE <htengshe.com> -
1. Server architecture(s) (please list all effected) (x86/POWER6/Z/etc.):
Z series (Z/VM Guest)

2. Server type (9117-MMA/HS20/s390/etc.):
s390, Z10 machine
Type: 2097
Model: 724 E26

3. Other components involved (ixgbe/java/emulex/etc.): NA

4. Does the server have the latest GA firmware?
Yes.

5. Has the problem been shown to occur on more than one system?
Yes
6. Collect "sosreport" from machine problem was found on, and attach to bug.
7. What is the latest official distro build on which this bug has been seen ?
RHEL6.0 Snap7

8. Steps to reproduce.
During First installation phase, when requested for DASD range:
input: "DASD=none"

9. Business justification. This is needed as we approach the end of the release
for RHEL6.
This is documentation error, input should be "none" for interactive input.

Comment 1 Joseph Kachuck 2011-02-01 19:17:00 UTC

I re-iterate from previous comments and confirm:

The mistake is in Red Hat Enterprise Linux Installation Guide at the end of chapter 19.6 in the text :
......
The installer requires the definition of a DASD.
If a SCSI-only installation is desired, enter a DASD=none parameter interactively in installation phase 1 or written into the parameter or CMS configuration file. This will satisfy the requirement for a defined DASD parameter, while resulting in a SCSI-only environment.
.....

Please correct the second sentence from wrong:
.., enter a DASD=none parameter ....

to correct:
.., enter a "none" parameter ...

Note: the user need to enter the parameter "none"

The second sentence in that text when corrected is

If a SCSI-only installation is desired, enter a "none" parameter interactively in installation phase 1 or written into the parameter or CMS configuration file.

Thank you IBM 

Joseph, this is indeed the correct component. Can you please confirm the version of the Installation Guide in which you see this error? You can find this information in the Revision History at the back of the guide.

The current version (1.0-4) is available at http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html-single/Installation_Guide/index.html

In this version, the text you identified is now towards the end of section 23.6, in the subsection "23.6.1.2.2. FCP Devices" and now reads:

Important — you must define a DASD
The installer requires the definition of a DASD. For a SCSI-only installation, enter none as the parameter interactively during phase 1 of an interactive installation, or add DASD=none in the parameter or CMS configuration file. This satisfies the requirement for a defined DASD parameter, while resulting in a SCSI-only environment. 

I believe that the problem reported in this bug has been fixed some time ago. 

Can you please review the text in the current version of the guide and confirm?
