configuration" on page 31

"Physical disk drive numbers do not match" on page 31
■
Extra hard disk drive space required when
upgrading to a Mirrored RAID configuration
You must have 100 MB of free unpartitioned disk space at the end of the hard disk
drive if you want to upgrade to a mirrored RAID configuration.
Upgrade path for data merging
The only upgrade path that supports data merging is from a single disk to a mirror.
This is a limitation of the LSI card. If you want to upgrade from a single disk to an
IME (Integrated Mirror Extension) or an IMS (Integrated Mirror Stripe), the data and
OS will be lost and a reinstallation and restore will be required.
Physical disk drive numbers do not match
If you are using an LSI RAID REM card (model number 4607A or X4607A) in your
Sun Blade X6240 server module, the physical disk drive numbers might not map
correctly to the blade's slot numbers.
