NOTE: You cannot use mixed physical disk types in the same disk group and virtual disk. This command fails if you specify different types of physical disks for the RAID virtual disk. Syntax create virtualDisk physicalDisks (enclosureID1,drawerID1,slotID1 enclosureID2,slotID2... enclosureIDn,drawerIDn,slotIDn) [diskGroupUserLabel=[diskGroupName]] raidLevel=(0 | 1 | 5 | 6) userLabel="virtualDiskName" [capacity=virtualDiskCapacity owner=(0 | 1) cacheReadPrefetch=(TRUE | FALSE) segmentSize=segmentSizeValue usageHint=(fileSystem | dataBase | multiMedia) enclosureLossProtect=(TRUE | FALSE) drawerLossProtect=(TRUE | FALSE) dssPreAllocate=(TRUE | FALSE) securityType=(none | capable | enabled)] Parameters Parameter physicalDisks Description Specifies the physical disks to assign to the created virtual disk. Specify the enclosure ID and slot ID for each unassigned physical disk to assign to the virtual disk. Enclosure ID values are 0 to 99. Drawer ID values are 0 to 4. Slot ID values are 0 to 31. You must put parentheses around the enclosure ID values and the slot ID values. diskGroupUserLabel The alphanumeric identifier (including - and _) that you want to give the new disk group. Enclose the disk group identifier in square brackets ([]). raidLevel RAID level of the disk group that contains the virtual disk. Valid values are 0, 1, 5, or 6. NOTE: If you set the raidLevel parameter to RAID 1, the RAID controller module firmware takes the list of physical disks and pairs them using the following algorithm: Data physical disk = X Consistency physical disk = N / 2 + X where, X goes from 1 to N / 2 and N is the number of physical disks in the list. The following data show an example of six physical disks and their mirror pairs. Data Consistency 1 N / 2 + 1 = 4 2 N / 2 + 1 = 5 3 N / 2 + 1 = 6 117
