Certain IBM® Enterprise Storage Server® (ESS) types are supported for use with the SAN Volume Controller.
Before you delete or unmap a logical unit (LU) from the
SAN Volume Controller,
remove the LU from the managed disk (MDisk) group. The following is
supported:
- LU size of 1 GB to 2 TB.
- RAID 5 and RAID 10 LUs.
- LUs can be added dynamically.
Attention: When adding additional SAN Volume Controller ports
to an existing LU, you must select the Use same ID/LUN
in source and target check box. Failure to select the Use
same ID/LUN in source and target checkbox can cause loss
in redundancy or a loss of data. If this checkbox is not available,
the option is not required. The detect MDisks task in the SAN Volume Controller Console or
the svctask detectmdisk command-line interface
(CLI) command must be run for the SAN Volume Controller to
detect the new disks.
