In Windows world sometimes a simple task becomes too complicated. Yesterday I was expanding the a lun on my Exchange CCR cluster. Normally easy task and used to be done without any downtime. Expanded the lun in the VMAXe and then in diskpart.
hmm… Diskpart and diskmanagement shows the disk expanded but not in My computer.
Restarted the computer no luck…. Then what helped me is again diskpart.
Diskpart: “extend filesystem” resolved the issue.
