Increase Virtual Disk Capacity On A Disk Pool

Description

This command defines the properties for a virtual disk. You can use most parameters to define properties for one or more virtual disks. You also can use some parameters to define properties for only one virtual disk. The syntax definitions are separated to show which parameters apply to several virtual disks and which apply to only one virtual disk. The syntax for virtual disk mapping is listed separately.
  • NOTE: In configurations where disk groups consist of more than 32 virtual disks, the operation can result in host I/O errors or internal RAID controller module reboots due to the expiration of the timeout period before the operation completes. If you experience host I/O errors or internal RAID controller module reboots, bring the host to a quiescent state I/O and try the operation again.

Syntax Applicable To One Or More Virtual Disks

start increaseVolCapacity virtualDisk = 
                                 virtualDiskName incrementalCapacity = 
                                 incrementalCapacity [addDrives = (drive-spec-list)]

Parameter

Parameter Description
addPhysicalDisks The setting to add new physical disks to the virtual disk. For dense expansion enclosures, specify the enclosure ID value, the drawer ID value, and the slot ID value for the physical disk. For non-dense expansion enclosures, specify the enclosure ID value and the slot ID value for the physical disk. Enclosure ID values are 0 to 99. Drawer ID values are 0 to 4. Slot ID values are 0 to 31. Enclose the enclosure ID value, drawer ID value, and the slot ID value in parentheses. Use this parameter with the addCapacity parameter if you need to specify additional physical disks to accommodate the new size.

Each disk pool must be created from a minimum of 11 physical disks specified. There is no upward limit of physical disks supported in a single disk pool, but the number cannot exceed the number of physical disks supported on the storage array.
