HDD Space Required When Upgrading to a
Mirror Configuration
You must leave 100 MB of free unpartitioned space at the end of the hard disk if you
plan on upgrading to a mirrored configuration.
Only Upgrade Path That Supports Data Merging
The only upgrade path that supports data merging is from a single disk to a mirror.
This is a limitation of the card. If you wish to upgrade from a single disk to an IMe
(Integrated Mirror Extension) or an IMS (Integrated Mirror Stripe), the operating
system and its data will be lost and a reinstall/restore will be required.
Server Might Hang With RAID Configuration in
Sync Mode
When a RAID set of disks is in sync mode, the server might hang if a reboot is
issued. This hang will cause the disk to lose its RAID configuration. Do not reboot
while a sync is in progress. This issue is being investigated.
