Omconfig reconfiguring virtual disks

Table 1. omconfig reconfiguring virtual disks . This table describes how to reconfiguring virtual disks

Description

Reconfigure a virtual disk to change the virtual disk’s RAID level or increase its size by either adding physical disks or using the available free space. On some controllers, you can also remove physical disks.

  • NOTE: If you want to reconfigure with an extra physical disk, the physical disk must be of the supported bus protocol, media type, sector size, T10 Protection Information capability, and encryption capability.

Syntax

omconfig storage vdisk action=reconfigure controller=id vdisk=id raid=<c| r0| r1| r1c| r5| r6| r10> pdisk=< PDISK> [size=< size> vdcapacityexpansion=yes sizeinpercent=<1 to 100>] , where id is the controller ID and virtual disk ID as reported by the omreport command.

  • NOTE: When you perform the virtual disk reconfiguration operation using the sizeinpercent/vdcapacityexpansion argument, Storage Management does not allow addition of physical disks to the existing reconfigured disk group. On successful operation, the virtual disk capacity is expanded, but the additional physical disk is not considered.
  • NOTE: To obtain these values, type omreport storage controller to display the controller IDs and then type omreport storage vdisk controller=ID to display the IDs for the virtual disks attached to the controller.

Example to

Reconfigure virtual disk 4 to a size of 800 MB, use RAID-5 and physical disks 0 through 3 on connector 0 of controller 1. On a SAS controller, the physical disks reside in enclosure 2.

Example for SCSI, SATA, and ATA controllers

omconfig storage vdisk action=reconfigure controller=1 vdisk=4 raid=r5 size=800m pdisk=0:0:0,0:1:1,0:2:0,0:3:2

Example for SAS controllers

omconfig storage vdisk action=reconfigure controller=1 vdisk=4 raid=r5 pdisk=0:2:0,0:2:1,0:2:2,0:2:3

Example to

Increase the size of the virtual disk by 20 percent using the available free space, use RAID-5 and physical disks 0 through 3 on connector 0 of controller 1. On a SAS controller, the physical disks reside in enclosure 2.

Example

omconfig storage vdisk action=reconfigure controller=1 vdisk=4 raid=r5 pdisk=0:2:0,0:2:1,0:2:2,0:2:3 vdcapacityexpansion=yes sizeinpercent=20

  • NOTE: The vdcapacityexpansion parameter is supported only on PERC H700 and PERC H800 controllers. If you set vdcapacityexpansion=yes, specify sizeinpercent. If you do not set vdcapacityexpansion, specify size.
  • NOTE: The sizeinpercent parameter is not supported on PERC S130 controller.
