<p class="MsoNormal">By default, GPFS does not automatically start down disks. You could add a callback “downdisk” via mmaddcallback that could trigger a “mmchdisk start” if you wanted. If a disk is marked down, it’s better to determine why before trying to
start it as it may involve other issues that need investigation.<u></u><u></u></p>

<span style="color:black">Does GPFS start “down” disks in a filesystem automatically? For instance, when connection to NSD is recovered, but it the meantime disk was put in “down” state by GPFS. Will GPFS in such case start the disk?<u></u><u></u></span></p>
