Hello again,

I am having difficulty accessing my linux system now that I have moved my
dasd packs.
Here are the facts:

1) I updated my parmfile to replace the old ucb's with the new ucb's

old = dasd=31A0,31A1 root=/dev/dasdb1 noinitrd

new = dasd=216A,216B,216C root=/dev/dasdb1 noinitrd

2) I ran silo:
lnx390t:cd /boot
lnx390t:/boot # silo -d /dev/dasdb -f image -p parmfile -b ipleckd.boot
o->ipldevice set to /dev/dasdb
o->image set to image
o->parmfile set to parmfile
o->bootsect set to ipleckd.boot
Testlevel is set to 0
IPL device is: '/dev/dasdb'
bootsector is: 'ipleckd.boot'...ok...
bootmap is set to: './boot.map'...ok...
Kernel image is: 'image'...ok...
original parameterfile is: 'parmfile'...ok...tempfile is ./parm.q9EPib
final parameterfile is: './parm.q9EPib'...ok...
ix 0: offset: 082b7a count: 0c address: 0x00000000
ix 1: offset: 082b87 count: 80 address: 0x0000c000
ix 2: offset: 082c07 count: 80 address: 0x0008c000
ix 3: offset: 082c87 count: 72 address: 0x0010c000
ix 4: offset: 082e03 count: 01 address: 0x00008000
Bootmap is in block no: 0x00082e04


3) I backed up my dasd w/ OFFLINDR

4) My system was brought down (not cleanly if that matters)
5) I activated my new IOCP to include new dasd devices
6) Restored data to vols : 31a0 to 216a etc...
7) IPL'd from 216B and received the following :

amongst other messages...

Command line is dasd=33a0,33a1 root=/dev/dasdb1 initrd ro   (<---this is a
bad sign)
....
detected device 216a
detected device 216b
detected device 216c
  (so my gen is looking good)
...

dasd: devn 0x33A1 on subchannel 9342=  /dev/dasdb (94:5) cannot open
unrecognized device.
VFS: cannot open root  5e:05

My guess is I "botched" SILO .


Is there a way to get this system up on the new dasd without  a complete
reinstall ?

TIA,
SG
