Save auto-load balancing statistics

The save storageArray autoLoadBalanceStatistics file command provides automated I/O workload balancing and ensures that incoming I/O traffic from the hosts is dynamically managed and balanced across both controllers.

Supported Arrays

This command applies to any individual storage array, including the E2700, E5600, E2800, E5700, EF600 and EF300 arrays, as long as all SMcli packages are installed.

Roles

To execute this command on an E2800, E5700, EF600, or EF300 storage array, you must have the Storage Admin role.

Context

This command saves the automatic load balancing statistics of the storage array to a file. These statistics show the ownership change history on each volume in the array.

Note: Send this file to technical support for interpretation.

Syntax

 save storageArray autoLoadBalanceStatistics file="filename" 
(numberOfDays=numberOfDays);

Parameters

Parameter	Description
storageArray	Specifies that this command works on a storage array.
file	The file path and the file name to which you want to save the auto-load balancing statistics. Enclose the file name in double quotation marks (" ").
numberOfDays	The number of days worth of statistics to save. This parameter is optional and the default value is 0, which indicates all available data.

Example

SMcli -n Array1 -c "save storageArray autoLoadBalanceStatistics file="filename" numberOfDays=30;"

Note: An active "Drive Lost Primary Path" condition will result in the Automatic Load Balancing incapable of balancing workloads. This condition must be inactive to ensure workloads are balanced through the Automatic Load Balancing feature.
