Table 145. omcong reconguring virtual disks
Description Recongure 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 recongure 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 reconguration operation using the
sizeinpercent/vdcapacityexpansion argument, Storage Management does not allow
addition of physical disks to the existing recongured 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 Recongure 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.
