Dear Red Hat users,

We use mdadm multipathing on a RHEL 4U5 server, but due to support
issues with IBM's SAN Volume Controller (SVC 4.1) need to switch to IBMsdd.

We use LVM on top of the SAN LUN's.

Can this be done 'on the fly'? I mean without rebuilding the
volumegroups and logical volumes and a data restore?

Personally I am afraid that the device names of the physical volumes
might change and am unsure what effect this has on the volumegroup

Kind regards,

Jan Gerrit Kootstra
