Cannot uninstall powerpath - bosboot issues

zxmaus · #1 (**permalink**) 4 Weeks Ago

Hi Guys,

I have a problem while trying to upgrade to more current EMC powerpath software on AIX 5.3 - respectively uninstalling the existing one.

I tried to deinstall the powerpath software with removed disks - was working perfectly fine on 12 servers - but number 13 is failing with errors:

Code:

installp:  bosboot verification starting...
installp:  An error occurred during bosboot verification processing.

And following filesets seem still to be there:

Code:

lslpp -L | grep -i emc
  EMCpower.base              5.1.1.2    C     F    PowerPath Base Driver and
  EMCpower.consistency_grp   5.1.1.2    C     F    PowerPath Consistency Group
  EMCpower.migration_enabler
  EMCpower.mpx               5.1.1.2    C     F    PowerPath Multi_Pathing

A forced overwrite with the new packages doesn’t work and a simple bosboot is failing too ... with following error:

Code:

bosboot -ad /dev/hdisk1

0301-154 bosboot: missing proto file: /etc/emcp_registration

bosboot -ad /dev/hdisk0

0301-154 bosboot: missing proto file: /etc/emcp_registration

The file is indeed not there - but it isn't on any of the other boxes either - not with and not without installed Powerpath stack.

Does anyone how I can get rid of the old powerpath software or get the new one onto the box.

Code:

oslevel -s
5300-08-06-0918

I did raise this issue with our storage engineering, IBM and EMC but did not get any help - they tell me 'ODM corruption' and 'ask IBM / EMC / engineering' - depending on who I asked - and that's it. Is anyone able to assist?

Thank you and regards
zxmaus
