Device configuration information is independently maintained in the performance management functionality.
To change the device configuration, update the device configuration information that is maintained by the performance management functionality according to the procedure shown below. Also perform the update if the configuration for a device used to execute performance monitoring and threshold monitoring has been changed.
If the configuration for a device used to execute performance monitoring and threshold monitoring has been changed, the configuration information before the update is used for performance monitoring and threshold monitoring. Performance information and threshold monitoring, shown in the procedure below, cannot be guaranteed prior to the configuration information update.
<Configuration information update procedure>
Record the performance monitoring settings contents (if performance monitoring is used)
<Recorded settings contents>
Interval before obtaining performance information (in seconds)
Performance monitoring targets (only for ETERNUS Disk storage system. Minimum LUN_V, Maximum LUN_V)
Stop performance monitoring (if performance monitoring is used)
Refer to "7.2.8 Instruction for stopping performance management".
For the storage device, the firmware is upgraded and the composition of the device is changed.
Note
The upgrade of firmware is needed only when the firmware version of the storage device must be changed to the version that supports the Eco-mode operation because of executing the performance management for the number of active disks. For the ETERNUS Disk storage systems that have the Eco-mode function, refer to "1.2.4 Energy-saving operation for storage device".
Start performance monitoring based on the settings contents recorded in step 1. (if performance monitoring is used).
Make sure to set it to create configuration information.
Refer to "7.2.2 Instruction for performance management" and "7.2.3 Setting monitoring intervals".
