After SBS 2003 R2 reinstall 4TB RAID5 array not present in disk manager
Posted on 2011-03-25
I had to reinstall SBS2003R2 after a bad stripe on the OS Partition caused lots of instability. (I have good backups, so this didn't phase me.)
I followed the article to reinstall the OS from the CD-ROM product and reapplied the SP1 (I wasn't using SP2) upgrade.
Now, when I look in My Computer the 4TB partition based on a RAID5 array isn't present. This is on an Adaptec 5085 controller.
However, the 950GB partition based on a RAID1 array is present on the same controller.
My OS is on an Adaptec 2820SA controller which has 2 other partitions on it as well.
Why is my 4TB partition visible in Adaptec Storage Manager but not visible in My Computer or SBS Storage Disk Management?
