Vdisk size

The maximum vdisk size is the total space available on the pdisks in the declustered array, taking into account the overhead of the RAID code, minus spare space, minus vdisk configuration data, and minus a small amount of space reserved as a buffer for write operations. IBM Storage Scale RAID will round up the requested vdisk size as required. When creating a vdisk, the user can specify to use all remaining space in the declustered array for that vdisk.
