Expand Vdisk - HP P2000 Reference Manual

expand vdisk

Description Adds disks to a vdisk. All disks used in a vdisk and its spares must be either SAS or SATA; mixing
disk types is not supported. Adding single-ported disks to a vdisk that contains dual-ported disks is
supported; however, because single-ported disks are not fault-tolerant, a confirmation prompt will
appear.
The expansion capability for each supported RAID level is:
RAID level
NRAID
0, 3, 5, 6
1
10
50
IMPORTANT:
disk type, RAID level, and other factors. Before starting a vdisk expansion, read the white paper "HP
P2000 G3 MSA Best Practices" at
http://h20195.www2.hp.com/v2/GetPDF.aspx/4AA3-2141ENW.pdf.
Syntax
expand vdisk
disks disks
[prompt yes|no]
vdisk
Parameters disks disks
IDs of the disks to add. For disk syntax, see
prompt yes|no
Optional. Specifies an automatic response to the confirmation prompt:
• yes: Allow the command to proceed.
• no: Cancel the command.
If this parameter is omitted, you must manually reply to the prompt.
vdisk
Name or serial number of the vdisk to expand. For vdisk syntax, see
Example Expand vdisk VD1 to include disk 1.1 1:
# expand vdisk disks 1.11 VD1
Depending on several factors, vdisk expansion can take a significant amount
of time to complete. The size of the physical disks in the original vdisk,
the amount of capacity being added, and the level of I/O activity during
expansion will influence the time of completion.
It is strongly recommended to review the Best Practices white paper before
starting a vdisk expansion. See the online help to access this white paper.

Success: Command completed successfully. - Expansion was started on vdisk VD1.

Cannot expand.
Can add 2 or 4 disks at a time.
Can expand the vdisk one RAID-5 sub-vdisk at a

the same number of disks as each original

Vdisk expansion cannot be stopped and can take days to complete, depending on
