LSI RAID Expansion Module (REM)
Issues
This section contains the following LSI RAID REM issues:
■ “Extra hard disk drive space required when upgrading to a Mirrored RAID
configuration” on page 26
■ “Upgrade path for data merging” on page 26
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.
