https://community.hpe.com/t5/proliant-servers-ml-dl-sl/add-drives-to-existing-raid-5/m-p/5603369#M149025 Hi, I have a ML350 G6 with raid 5 configured. I'm wondering if it's possible to add an additional drive to the raid array without rebuilding the whole array ie. I don't loose any data and just expand the array? If possible, does anyone know how VMware vSphere 5.0 handles this? Do I need to rebuild the datastore or can I just expand it? Thanks, -Patric Fri, 30 Mar 2012 12:40:30 GMT Patric Falinder 2012-03-30T12:40:30Z https://community.hpe.com/t5/proliant-servers-ml-dl-sl/add-drives-to-existing-raid-5/m-p/5603369#M149025 Hi, I have a ML350 G6 with raid 5 configured.
