Here is a breakdown of the hardware and software involved.
Windows 2003 Server R2 w/ SP2
Dell PowerEdge 1950
Dual Socket dual core 3Ghz processors
4 GB RAM
Dual Onboard Broadcom NICs
EMC Clariion SAN
2 DAE's with 30 750 GB drives
Server is connected via iSCSI to the SAN and this is my first iSCSI experience.
I configured a MetaLUN in Navisphere and assigned 100% of the LUN the a Storage Group called "File Server Storage". I then assigned the server to that storage group and was able to see the new storage.
The original size of the MetaLUN was approx 15TB RAW and consisted of 5 RAID 5 LUNs that included 5 750 GB drives each. After creating this MetaLUN 5 disks reamained unused. (relevant later).
I registered the Storage Processors as Target Portals in the MS iSCSI innitiator and created a persistant connection to the now seen iSCSI targets. I then refreshed Device Manager and had LDM rescan the BUS to discover the new storage. I converted the storage to a dynamic GPT volume and formatted it using NTFS and gave it the drive letter "E".
Once the storage was usable I made it persistant and tested data transfer with no issues.
I was confident the storage and began my data migration from tape backup. I was moving nearly 5 TB of data from an older XRAID and this process took almost a week.
Once the migration was done. I decided to extend the volume. This is a 2 step process. First off I created another 3TB LUN and then extended the MetaLUN to include the new LUN. Once that was done I refreshed LDM and saw the new unused storage space.
I then used diskpart.exe to extend the volume. This finished with no errors and said that the volume had been exteneded successfully. I refreshed LDM and in the bottom view it showed the correct size of 16+TB. Though when I looked at the volume properties above it still showed the original size of 13+TB.
I researched this issue and found this MS office which seems right on.
I followed the articles instructions and used the "extend filesystem" command to further extend the volume. After issuing the command I get a successful return but no change is made.
At this point I have a volume that shows correctly in LDM but incorrectly when disk properties are returned in My Computer or other Explorer views.
Any ideas or help would be greatly appreciated.
