Hi, further to a previous enquiry, I am trying to get a definitive answer to whether unallocated disk space is usable on the 7K HDD storage on a SC4020 SAN. Each disk is showing only 71.66% allocated and (6.47TB out of 9.03TB capacity). There is 2.56TB free space on each HDD (adding up to 51.26TB) which does not appear to be usable without reconfiguration. This can be seen in the attached screenshot. Any advice would be welcome.

Thanks

Richard W
