Expand Raid-Group - Fujitsu Eternus DX100 S3 User Manual

3.1 RAID Group Management > expand raid-group

expand raid-group

This command expands a RAID group (Logical Device Expansion). The capacity of an existing RAID group is
expanded by adding new disks to the RAID group. A new RAID level can also be specified. Any volumes in the
existing RAID group are relocated to the new RAID group.
•
RAID5+0 is not supported, not even for pure capacity expansion operations.
•
Expanding a RAID level other than RAID0 to RAID0 is not supported.
•
When RAID group capacity is expanded without changing the RAID level, specify only the new disks to be added for the
"-disks" parameter.
•
If the RAID level is changed with RAID group expansion, at least one disk that is already configured in an expansion
source RAID group and all the new disks that are to be added must be specified for the '-disks' parameter.
