We frequently run into an issue that requires a system reboot when it seems that one shouldn't be necessary. Any advice would be appreciated. Here are the details:
A Windows 2000 host had access via fibre channel to a LUN with 600GB of storage on a HP EVA 5000. The filesystem started filling up so the LUN ("vdisk") on the EVA was extended to 700GB.
Normally our next step to use the new space would be to go to Computer Management, right-click on Disk Management and choose "Rescan Disks". The OS would then realize there's 100GB of unused space at the end of the drive, and diskpart could be used to extend the file system.
On this host however, the Rescan Disks command has no effect. Despite having confirmed on the EVA that the vdisk/LUN extension to 700GB has completed, the host still reports the same 600GB disk size.
In the past every time that this happens, the OS will recognize the new space immediately after a reboot. But, we've so far been unsuccessful in finding a way to make use of the new space without rebooting.
My questions are: 1) Is this a common/known issue? 2) Are there any steps we're missing or should do differently? 3) Is there any way to make use of the new space without rebooting the entire system?
