-When the number of volumes to be concatenated is fewer than the maximum number of

volumes that can be concatenated but the resulting capacity exceeds the maximum single

LUN capacity allowed by the ETERNUS DX Disk storage system.

•It is possible to add extra volumes to an already concatenated volume.

•After concatenation, any number of formatting processes can be started at once.

•Because the server-side LUNs are not changed by volume concatenation, an OS reboot is

not required. However, this function only expands the volumes in the ETERNUS DX Disk

storage system. Server-side recognition and volume expansion is OS dependent.

•The logical unit number of each concatenated volume does not change and remains

accessible from the server before, during, and after the concatenation.

•If the power is turned off or an electrical power outage occurs during LUN Concatenation, the

concatenation will simply continue the next time the power is turned on.

•It is recommended that the data on the volumes that are to be concatenated be backed up

first.

•When LUN Concatenation is used to increase the volume (LUN) capacities, note that the

increased size of the expanded volumes may not always be dynamically re-recognized by the

server, depending on the server-side OS (type and version) being used. Refer to the

applicable OS and file system documentation before dynamically expanding the volume

capacity.

This is not necessary when building a new system after the volume capacity has been

expanded.

•A concatenated volume can be used as an OPC, EC, or QuickOPC copy source or copy

destination. It can also be used as a SnapOPC+ copy source.

•When a volume that is using ETERNUS SF AdvancedCopy Manager to run backups is

expanded via LUN Concatenation, the volume will need to be registered with ETERNUS SF

AdvancedCopy Manager again.
