Action	Description
Create a new virtual disk	Creates a new virtual disk from one or more physical disks. You can configure hot spares when you create a virtual disk.
Manage dedicated hot spares	Creates or deletes a hot spare, which is dedicated to a single redundant virtual disk.
Initialize a virtual disk	Initializes the selected virtual disk. You must initialize every virtual disk that is configured. You can perform a fast initialization or a full initialization.
Check data consistency on a virtual disk	Verifies the correctness of the redundancy data in the selected virtual disk. The option is available only if RAID level 1, 5, 6, 10, 50, or 60 is used. The PERC 9 series of cards automatically correct any differences found in the data.
Display or update virtual disk parameters	Displays the properties of the selected virtual disk. You can modify the cache write policy and read policy from the menu.
Manage preserved cache	Preserves the dirty cache from a virtual disk if it goes offline or is deleted. The dirty cache is preserved until you import the virtual disk or discard the cache.
Delete a virtual disk	Deletes the virtual disk and frees up disk space to create another virtual disk.
Delete a disk group	Deletes a disk group, which is a collection of disks from one or more disk subsystems controlled by the management software.
