Displaying Performance Information of NAS Volume and NAS System

Select the performance information you want to display and display the graph.
Note
If the ETERNUS Disk storage system does not support NAS functionality, performance information of NAS volumes and NAS systems
is not displayed. Even if NAS functionality is supported, it is necessary to update to supported firmware (V10L21-0000 or later) and
perform "Required Setup
it is necessary to update configuration information and restart performance monitoring.

Examples of Use of Performance Management

If an I/O delay from the server node to a storage system occurs, the user can check for the cause in the storage system by using the
methods described below. These are only examples, so all causes of I/O delays cannot be determined by use of these methods.
1.
Identify the time when the I/O processing delay occurred and the access path where the delay occurred.
2.
Use this software to check the Affinity Group number and Logical Volume number of the ETERNUS Disk storage system defined
in the target access path.
3.
Using performance management, display and check the target Logical Volume performance values.
4.
If a response of the Logical Volume unit takes a long time, check RAID Group performance. If a response of RAID Group also
takes a long time, find another Logical Volume belonging to RAID Group, and find the LUNs to which the Logical Volume is
allocated. Check the I/O statuses of these Logical Volumes, and check for a heavy load on RAID Group. If there is a heavy load,
move the appropriate Logical Volume to another RAID Group, or take other appropriate action.
