-f

Do not ask for confirmation.

SPECIFIERS

None.

RESTRICTIONS

None

•

This command requires a Dynamic Optimization license. Contact your local HP representative

for information.

EXAMPLES

In the following example:

•

VVs will be re-balanced between nodes if there is an imbalance in space usage between

nodes of more than 5% (

nodepct

value).

•

PD chunklets will be re-balanced on each node if any disk has usage less than 20% than the

average chunklet usage (

chunkpct

value).

•

A maximum of 4 tune tasks will be run at a time (

maxtasks

value)..

•

A maximum of 5 chunklets will be moved at a time (

maxchunk

value).

cli% tunesys -f -nodepct 5 -chunkpct 20 -maxchunk 5 -maxtasks 4

Task 999 started

NOTES

•

Virtual volumes associated with CPGs which are in Adaptive Optimization configurations will

not be tuned by

tunesys

•

When the

-cpg

option is used, if the user space and snap space of a virtual volume are from

different CPGs, then only the space associated with the named CPG will be tuned. Also, no

tunes will be generated for any virtual volumes outside of CPGs; for example, tunes created

with the

createaldvv

command.

•

When the

-cpg

option is used or when the user does not have All Domain privileges, intra-node

analysis & tuning will not take place. Intra-node tunes require access across all CPGs and all

domains in order to work correctly.

•

When canceling a

tunesys

command task, the

canceltask

command can return before

a cancellation is completed. Therefore, resources reserved for the task might not be immediately

available. This can prevent actions like restarting the canceled

tunesys

command task for

a few minutes.

•

tunesys

runs between 1 and 3 phases depending on the options specified.

Phase 1 - Analyzes and rebalances space usage between nodes (inter-node tuning).

◦

Phase 2 - Analyzes and rebalances space usage between disks associated with each

node (intra-node tuning).

◦

Phase 3 - LD re-layout tunes. LDs where the current characteristics differ from the associated

CPG are re-laid out to mathc the CPG.

•

When

tunesys

is running,

showtask

will show the current and maximum number of phases

for the task. The steps displayed are the number of subordinate tunes that need to be run to
