[name new-name]
[owner a|b]
[spin-down-delay delay]
disk-group
Parameters
[adapt-spare-capacity size [B|KB|MB|GB|TB|KiB|MiB|GiB|TiB]|default]
Optional. For an ADAPT disk group, this specifies the target spare capacity.
● size [B|KB|MB|GB|TB|KiB|MiB|GiB|TiB]: Sets the target spare capacity to a specific size. The
unit is optional (B represents bytes). If no unit is specified, GiB will be used, regardless of the
current base. Whichever unit is set, internally the value will be rounded down to the nearest
GiB. If the value is set to 0, the absolute minimum spare space will be used. If this parameter is
omitted, the default setting will be used.
● default: Sets the target spare capacity to the sum of the two largest disks in the disk group,
which is sufficient to fully recover fault tolerance after loss of any two disks in the group.
name new-name
Optional. A new name for the disk group. A name that includes a space must be enclosed in double
quotes.
owner a|b
Optional for a linear disk group. Prohibited for a virtual disk group. Sets the new owner: controller A
or B.
CAUTION: Before changing the owning controller for a linear disk group, you must stop
host I/O to its volumes. Volume mappings are not affected.
NOTE: Changing ownership of a disk group while any volumes in the disk group are mapped to
live hosts is not supported and may cause data loss or unavailability. All volumes in the disk group
must be unmapped or attached hosts must be shut down before the ownership of a disk group is
changed.
spin-down-delay delay
Optional for a linear disk group. Prohibited for a virtual disk group. Not applicable for ADAPT. For
spinning disks in a linear disk group, this sets the period of inactivity after which the disks and
dedicated spares will automatically spin down. Setting the delay to 1–360 minutes will enable spin
down; setting the delay to 0 will disable spin down.
NOTE:
Drive spin down affects disk operations as follows:
● Spun-down disks are not polled for SMART events.
● Operations requiring access to disks may be delayed while the disks are spinning back up.
disk-group
Name or serial number of the disk group to change. A name that includes a space must be enclosed in
double quotes.
Examples
Rename virtual disk group dgA01 to vdg.
# set disk-group name vdg dgA01
Rename linear disk group dg1 to dg2 and set its spin-down delay to 10 minutes.
# set disk-group name dg2 spin-down-delay 10 dg1

set disk-parameters
Description
Sets parameters that affect disk operation. Two features controlled by these parameters are disk
Self-Monitoring Analysis and Reporting Technology (SMART) and drive spin down.
