create vdisk Description Creates a vdisk using the specified RAID level, disks, and spares. All disks used in a vdisk and its spares must be either SAS or SATA; mixing disk types is not supported. For each RAID level, the minimum and maximum numbers of disks supported are: • NRAID: 1 • RAID 0: 2-16 • RAID 1: 2 • RAID 3: 3-16 • RAID 5: 3-16 • RAID 6: 4-16 • RAID 10: 4-16 • RAID 50: 6-32 Syntax create vdisk level nraid|raid0|r0|raid1|r1|raid3|r3|raid5|r5|raid6|r6|raid10|r10 |raid50|r50 disks disks [assigned-to a|b|auto] [spare disks] [chunk-size 16k|32k|64k] [mode online|offline] name Parameters level nraid|raid0|r0|raid1|r1|raid3|r3|raid5|r5|raid6|r6|raid10|r10 |raid50|r50 Specifies the RAID level. disks disks IDs of the disks to include in the vdisk. RAID 10 requires a minimum of two RAID-1 sub-vdisks each having two disks. RAID 50 requires a minimum of two RAID-5 sub-vdisks each having three disks. For syntax, see Command syntax. assigned-to a|b|auto Optional. The controller to own the vdisk. To have the system automatically load-balance vdisks between controllers, use auto or omit this parameter. spare disks Optional. IDs of 1-4 dedicated spares to assign to a RAID 1, 3, 5, 6, 10, or 50 vdisk. For syntax, see Command syntax. chunk-size 16k|32k|64k Optional. The amount of contiguous data, in KB, that is written to a vdisk member before moving to the next member of the vdisk. For RAID 50, this option sets the chunk size of each RAID-5 subvdisk. The chunk size of the RAID-50 vdisk is calculated as: configured-chunk-size x (subvdisk-members - 1). The default is 64k. mode online|offline Optional. Specifies whether the vdisk is initialized online or offline. • online: Enables you to use the vdisk immediately after creating it while it is initializing. Because online uses the verify method to create the vdisk, it takes longer to complete initializing than offline. Online initialization is fault tolerant. This option is the default. • offline: You must wait for the vdisk initialization process to finish before using the vdisk; however, offline takes less time to complete initializing than online. At the time of creation, a vdisk using offline initialization can have either one volume or none. If you want the vdisk to have more than one volume, create the vdisk with no volumes and then add volumes after initialization is complete. name A name for the new vdisk. The name is case sensitive, cannot include a comma, double quote, or backslash, and can have a maximum of 17 bytes. A name that includes a space must be enclosed in double quotes.
