You can create a new managed disk (MDisk) group using the Create a Managed Disk Group wizard.
If you intend to keep the virtual disk (VDisk) allocation within one disk controller system, ensure that the MDisk group that corresponds with a single disk controller system is presented by that disk controller system. This also enables nondisruptive migration of data from one disk controller system to another disk controller system and simplifies the decommissioning process if you want to decommission a disk controller system at a later time.
Ensure all MDisks that are allocated to a single MDisk group are of the same RAID-type. Using the same RAID-type ensures that a single failure of a physical disk in the disk controller system does not take the entire group offline. For example, if you have three RAID-5 arrays in one group and add a non-RAID disk to this group, you lose access to all the data that is striped across the group if the non-RAID disk fails. Similarly, for performance reasons, you should not mix RAID types.
If you are using a SAN Volume Controller solid-state drive (SSD) managed disk, ensure that you are familiar with the SSD configuration rules.
This task assumes that you have already launched the SAN Volume Controller Console.
Perform the following steps to create a new MDisk group:
