A brute force method for SLES 9  would be to edit the initial ramdisk's
/linuxrc script to insert lines like
/sbin/dasd_configure 0.0.16zz 1 0 

after the the group of lines that now say
/sbin/dasd_configure 0.0.15xx 1 0

For each zz in 16zz substitute its corresponding xx from 15xx so the
dasd's will be activated in the correct order: dasda dasdb etc.

then re-run zipl and reboot off the 16zz address that corresponds to the
15xx dasd.   

See IBM DeveloperWorks url, for 'Linux initial RAM disk (initrd)
overview'
http://www-128.ibm.com/developerworks/linux/library/l-initrd.html?ca=dgr

  It'll tell you how to unpack your initial ramdisk to get at /linuxrc
script and how to remake the initial ramdisk. It's not difficult.

Subject: Changing DASD addresses

A colleague had a test Linux server running in a partition on one
machine, but has now been moved to a different machine where the same
DASD devices are mapped to a different address range (16xx as opposed to
15xx). Needless to say, booting his Linux server doesn't result in a
great deal of success.

Assuming he is able, temporarily, to revert to the original addresses
and bring his system up, is there some way to tell Linux about the new
addresses?

Many thanks,
Ray Mansell
