I have a Windows 2008 R2 Ent server which has an NTFS D-drive which was a 1200GB LUN on our EMC VNX5300 SAN. The DBAs asked one of the Systems team members to increase the LUN so that the WIndows partition could be increased to accomodate the growing database. The D-Drive is an MBR style partition.
The Systems guy increased the LUN on the SAN to 2050GB but when he looked on the server, the available disk space in Disk Manager has not changed- there is no extra disk space to increase the partition on?
I’m not sure what is going on. Normally when you expand a LUN the extra space is visible in Windows Disk Manager.
