Required Privileges

ISI_PRIV_SMARTPOOLS

Options

--automatically-manage-protection {all | files_at_default | none}

Specifies whether SmartPools manages files' protection settings.

--automatically-manage-io-optimization {all | files_at_default | none}

Specifies whether SmartPools manages I/O optimization settings for files.

--protect-directories-one-level-higher {yes | no}

Protects directories at one level higher.

--global-namespace-acceleration-enabled {yes | no}

Enables or disables global namespace acceleration.

--virtual-hot-spare-deny-writes {yes | no}

Denies new data writes to the virtual hot spare.

--virtual-hot-spare-hide-spare {yes | no}

Reduces the amount of available space for the virtual hot spare.

--virtual-hot-spare-limit-drives <integer>

Specifies the maximum number of virtual drives.

--virtual-hot-spare-limit-percent <integer>

Limits the percentage of node resources that is allocated to virtual hot spare.

--spillover-target <string>

Specifies the target for spillover.

--spillover-anywhere

Globally sets spillover to anywhere.

--spillover-enabled {yes | no}

Enables or disables spillover. If spillover is enabled, writes will spill over into pools within spillover_target as needed.

--ssd-l3-cache-default-enabled {yes | no}

Enables or disables SSDs on new node pools to serve as L3 cache.

--ssd-qab-mirrors {one | all}

Specifies that either one QAB (quota accounting block) mirror, or all QAB mirrors, be stored on SSDs. The default is for one mirror to be stored on SSDs. By specifying all, system access to the QAB is likely to be faster.

--ssd-system-btree-mirrors {one | all}

Specifies that either one system B-tree mirror, or all system B-tree mirrors, be stored on SSDs. The default is for one mirror to be stored on SSDs. By specifying all, system access to the B-tree is likely to be faster.

--ssd-system-delta-mirrors {one | all}

Specifies that either one system delta mirror, or all system delta mirrors, be stored on SSDs. The default is for one mirror to be stored on SSDs. By specifying all, access to the system delta is likely to be faster.

--verbose

Enables verbose messaging.

Examples

The following command specifies that SSDs on newly created node pools are to be used as L3 cache:

isi storagepool settings modify --ssd-l3-cache-default-enabled yes

The following command specifies that 20 percent of node resources can be used for the virtual hot spare:

isi storagepool settings modify --virtual-hot-spare-limit-percent 20
