Configuring and Managing RAID 101
Virtual Disk Actions
Table 6-4 describes the actions you can perform on virtual disks. For
procedures you can use to perform these actions, See "Physical Disk
Management" on page 105.
Physical Disk Management (PD Mgmt)
The Physical Disk Management screen (PD Mgmt) displays physical disk
information and action menus. The screen displays physical disk IDs, vendor
names, disk size, type, state, and disk group (DG). You can sort the list of
physical disks based on these headings. You can perform several actions on
the physical disks, including the following:
• Rebuilding physical disks
Table 6-4. Virtual Disk Actions

disk

redundant virtual disks.
Initialize a virtual
disk
Initializes the selected virtual disk. You must initialize every
virtual disk that is configured. You can perform a fast

virtual disk
Verifies the correctness of the redundancy data in the selected
virtual disk. This option is available only if RAID level 1, 5, 6,

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 management software.
