Microsoft® documentation tells you to disable
disk mirroring and disconnect any uninterruptible power supply before installing
or upgrading Windows server. Be aware that this does not apply to disk mirroring
or an uninterruptible power supply that you have on your iSeries™.
If you have an Integrated xSeries® Server, an Integrated xSeries Adapter,
or an iSCSI HBA that is not listed in the
Hardware requirements section,
see the
IBM® Integrated xSeries solutions
web
site for installation instructions.
