5.2.5
Expand Volume
This function concatenates a new volume to the selected volume by using the LUN Concatena-
tion function to expand the volume capacity that can be used from the server.
Volume expansion provides the following features:
•
Volume capacity can be expanded by using the free space in an existing RAID group.
•
A volume with a maximum capacity of 128TB can be created.
•
Concatenation can be performed among multiple RAID groups.
•
Any RAID level can be applied for a concatenation source volume and a concatenation
destination volume. Concatenation can be performed regardless of the RAID level for the
concatenation source volume and the concatenation destination volume.
•
Data can be accessed from the host in the same way regardless of the concatenation status
(before, during, or after concatenation).
•
When the number of volumes in a concatenated volume is 15 or less, volumes can be added
to the existing concatenated volume.
