I've recently picked up a new client wanting me to upgrade their server. It's a HP ProLiant ML330 G6 running Windows SBS 2008, with a HP P410 RAID card and two 146 GB SAS 15k disks.
Now, all they asked was for more disk space but while investigating I noticed whoever did their setup previously set up an array on one disk without using RAID, so there's a completely unused disk in there. Their staff do rotating off site backups nightly but I still feel uncomfortable about leaving the machine like this, especially when there's a perfectly good drive sitting there.
The system is currently partitioned 50% system/50% data, and both partitions are full. I'd like to migrate the data partition to 2x new SATA disks and expand the system partition. SAS disks are absolutely overkill for their requirements (<10 staff, used for Exchange, file sharing and a small database app).
What I imagine I need to do is image the drive, destroy the array, recreate it in RAID 1 then reimage the system back onto it, and then add another two disks to a separate RAID array and migrate the data partition onto that.
1. What software should I use to perform this? I'm not sure if the RAID card is going to introduce any headaches.
2. If I set up the new data array with the same data and same drive letter as the previous partition, would that be an issue?
3. What's the best way to set up the arrays without an OS installed?
