tunesys
DESCRIPTION
The tunesys command is used to analyze and detect poor layout and disk utilization across an
entire HP 3PAR storage system array. This command runs a series of low level operations to affect
a re-balance of resources on the system.
SYNTAX
tunesys [options]
AUTHORITY
Super, Edit
Any role granted the sys_tune right
OPTIONS
-cpg <CPG name | patterns>
Limits the scope of a tunesys operation to the named CPG(s). The specified CPGs must all be in
the same domain as the user. The -diskpct and -chunkpct options cannot be used with this
option.
-nodepct <percentage>
Control the detection of any imbalance between LD capacity allocation between nodes. If any LD
in a group is <percentage> greater than the average of the group, then the VVs associated with
that LD will be tuned. The <percentage> parameter must be between 1 and 100. The default
value is 3.
-chunkpct <percentage>
Control the detection of any imbalance in PD chunklet allocation between PDs owned by individual
nodes. If a PD has utilization of <percentage> less than the average for that device type, then
that disk can potentially be tuned. Used in conjunction with the diskpct option. <percentage>
must be between 1 and 100. The default value is 10. This option cannot be used with the -cpg
option.
-diskpct <percentage>
Specify the percentage of disks identified by the -chunkpct option over which PD chunklet level
tuning will be started. <percentage> must be between 1 and 100. The default value is 10. This
option cannot be used with the -cpg option.
-maxtasks <number>
Specify the maximum number of individual tune tasks which the tunesys command can run at a
time. <number> must be between 1 and 8. The default value is 2.
-maxchunk <number>
Specifies the maximum number of chunklets which can be moved from any PD in a single operation.
<number> must be between 1 and 8. The default value is 2.
-tunenodech
Specify that only intra-node chunklet level rebalancing should be performed.
-dr
Specify that the command is a dry run and that the system will not be tuned. The result of the
analysis can be found in the task detail log (showtask -d taskid).
-waittask
