28 Tuning the System Whether new nodes are added or there are cage, magazine, or disk upgrades, the Tune System feature allows you optimize system performance by reallocating space for virtual volumes and logical disks, and reallocating chunklets across physical disks. Tune System runs only for those domains for which the user is authorized. If the user does not have authorization for all domains, intranode and chunklet level tuning will fail. There are three possible types of tunes, all of which run as a background task: • "Tune System" (page 360) - Detects physical disk space usage imbalance between nodes and rebalances virtual volumes between nodes, detects newly added disks and rebalances chunklets from a node's existing physical disks to its under-allocated ones, and performs a re-layout of LDs whose characteristics do not match their parent CPG. NOTE: Tuning a system can take anywhere from a few hours to several days. If the System Manger has restarted during that time, you may not see the task information, and you should check the log for failures. • "Tune CPGs" (page 365) - Performs the same task as Tune system but limits the retuning to a specific CPG. • "Tune Physical Disk Chunklets Only" (page 366) - (Option available for 3.1.2 systems only.) Rebalances a node's physical disks at the chunklet level. This option is aimed at systems where new disks have been added to a node. It is run on a per-node basis. Tune System The tuning process is slightly difference for 3.1.1 and 3.1.2 systems. Procedural instructions for both systems are provided. To access the Tune system feature: 1. Select Provisioning in the Manager Pane. 2. Click Tune System in the Common Actions panel. The Tune System wizard appears. 3. Select the system you want to tune from the System list. 4. Select the Tune system radio button. Follow the instructions related to your system: "Tuning 3.1.2 Systems" (page 360) "Tuning 3.1.1 Systems" (page 363) Tuning 3.1.2 Systems With 3.1.2 systems there are three types of tunes available: Tune system, Tune CPGs, and Tune physical disk chunklets only. When Tune system is selected, you have the option of changing the following settings: • Volume Allocation Imbalance Threshold - The percentage above the average space allocated across nodes at which a volume is considered out of balance. • Chunklet Allocation Imbalance Threshold - The percentage above the average (for physical disks of one device type on a single node) at which the number of chunklets allocated to a physical disk is considered out of balance. 360 Tuning the System

28 Tuning the System

Whether new nodes are added or there are cage, magazine, or disk upgrades, the

Tune System

feature allows you optimize system performance by reallocating space for virtual volumes and

logical disks, and reallocating chunklets across physical disks.

Tune System runs only for those domains for which the user is authorized. If the user does not have

authorization for all domains, intranode and chunklet level tuning will fail.

There are three possible types of tunes, all of which run as a background task:

•

“Tune System” (page 360)

– Detects physical disk space usage imbalance between nodes and

rebalances virtual volumes between nodes, detects newly added disks and rebalances chunklets

from a node's existing physical disks to its under-allocated ones, and performs a re-layout of

LDs whose characteristics do not match their parent CPG.

NOTE:

Tuning a system can take anywhere from a few hours to several days. If the System

Manger has restarted during that time, you may not see the task information, and you should

check the log for failures.

•

“Tune CPGs” (page 365)

– Performs the same task as Tune system but limits the retuning to a

specific CPG.

•

“Tune Physical Disk Chunklets Only” (page 366)

– (Option available for 3.1.2 systems only.)

Rebalances a node's physical disks at the chunklet level. This option is aimed at systems where

new disks have been added to a node. It is run on a per-node basis.

Tune System

The tuning process is slightly difference for 3.1.1 and 3.1.2 systems. Procedural instructions for

both systems are provided.

To access the Tune system feature:

Select Provisioning in the Manager Pane.

Click Tune System in the Common Actions panel.

The

Tune System

wizard appears.

Select the system you want to tune from the

System

list.

Select the

Tune system

radio button.

Follow the instructions related to your system:

“Tuning 3.1.2 Systems” (page 360)

“Tuning 3.1.1 Systems” (page 363)

Tuning 3.1.2 Systems

With 3.1.2 systems there are three types of tunes available:

Tune system

Tune CPGs

, and

Tune

physical disk chunklets only

When

Tune system

is selected, you have the option of changing the following settings:

•

Volume Allocation Imbalance Threshold

– The percentage above the average space allocated

across nodes at which a volume is considered out of balance.

•

Chunklet Allocation Imbalance Threshold

– The percentage above the average (for physical

disks of one device type on a single node) at which the number of chunklets allocated to a

physical disk is considered out of balance.
