Unhappy cannot see space added to netapp partition


The backup partition was 100 GB. I asked the netapp admin to add 200 GB and he told me it was done and the partition is now 300 GB. I can't resize with fdisk or parted, both act like there's only 100 GB available. I tried lvresize and it said 0 space available to add. Any ideas on how I can get the Linux system to recognize the added space and steps I need to do. If you just give me the command and order, I'll figure out the rest.

Here's some additional information:

The 300 GB partition shows up as sdc. sdc and sdd are mapped to netapp device for the same lun. dm-13 shows as where the volumegroup points to, but dm-13 is does not show a partition with fdisk as sdc, sdd, and dm-8 do. I can find no other reference to dm-8. The pvdisplay shows dm-11 as the pv, however dm11 doesn't have proper partition infomation via fdisk. I'm trying to be able to use the extra 200 GB of space that was added, and have tried fdisk, parted, lvresize, and pvresize. Please help me with what I'm missing.
