Peter, I hope the zipl command will also be enhanced to work with a multipathed LUN ala the multipath-tools package.
Or by making it support LVM (which relies on device mapper) will it automatically support multipathed LUN since multipath-tools also relies on device mapper? On my SLES10 SP1, zipl of multipath boot LUN complains: zipl -V Using config file '/etc/zipl.conf' Error: Unsupported device driver 'device-mapper' -------------------------------------------------------- This e-mail, including any attachments, may be confidential, privileged or otherwise legally protected.

The reason behind this is that zipl lacks knowledge about this type of device which prevents it from putting the right type of IPL record into the right place. Because this can cause various types of malfunctions, current versions of zipl even check whether they're pointed at a DASD or ZFCP disk and bail out if neither is the case. This is being worked on and some future version of zipl should be able to cope with a defined set of logical volume setups (no dates given though).
