1. Limiting data quantity You can limit the amount of data that is collected and presented which can be useful if your configuration includes numerous arrays physical disks and virtual disks To limit the arrays for which HP Command View EVAPerf collects data enter the following command evaperf as sz arrayl arrayl0 array32 The output contains data for the specified arrays only To limit the virtual disks for which HP Command View EVAPerf collects data enter the following command evaperf vd fvd disk2 disk4 disk8 The output contains data for the specified virtual disks only HP StorageWorks Command View EVA user guide 43 Filtering data You can filter the data that is collected for specific items such as a word or a host port name For example enter the following command evaperf as sz arrayl array2 fd test The output indicates where test appears on array 1 or array 2 Specifying data output in multiple files You can generate output for several commands and save the output for each command in a separate file organized by array When you run the mof command with the csv and od modifiers it executes the 1s as cs vd vdg hc ps hps pd pdg and drt commands and saves the output of each command for each array in a separate CSV formatted file in the directory you specify The naming convention for each file is array name command name date and time stamp csv For example enter the following command to store the out

Use HP StorageWorks Command View EVAPerf to monitor and display EVA performance metrics from a command line interface or a graphical user interface You can also view performance metrics in an external application such as Microsoft Excel after you export data to either a CSV comma separated value or TSV tab separated valve format You can monitor and display the following metrics e Arrays e Array controllers e Host connections e Host port statistics e Physical disks e Port status e Replication e Virtual disks Components HP Command View EVAPerf components are installed in the following directory C Program Files Hewlett Packard EVA Performance Monitor The software components are evapdcs exe EVA Data Collection service which gathers data from the EVAs that are visible to a host and stores it in memory cache evaperf exe HP Command View EVAPerf command line interface e evapmext d11 DLL extension for Windows Performance Monitor the graphical user interface EVAPerf TLViz Formatter exe EVAPerf TLViz Formatter user interface which formats the HP Command View EVAPerf a11 command output so you can view it with the HP TLViz tool EVADATA MDB A Microsoft Access database template you can use to view the all command output in a database The data from the command output resides in individual tables MSADODC OcCx This file is required to operate the EVAPerf TLVIZ Formatter use interface Configuring H
3. A virtual disk called a Vdisk in the user interface is a simulated disk drive created in a disk group You can assign a combination of characteristics to a virtual disk such as a name redundancy level and size Some operating systems require a logical unit number You can change the OS unit ID when you create a virtual disk For OpenVMS and Tru64 UNIX enter a unique OS unit ID for each virtual disk Presenting virtual disks to hosts Presenting a virtual disk offers its storage to a host To make a virtual disk available to a host you must present it You can present a virtual disk to a host during or after virtual disk creation The virtual disk creation must be complete before the host presentation can occur If you choose host presentation during virtual disk creation the management agent cannot complete any other task until that virtual disk is created and presented Therefore HP recommends that you wait until a virtual disk is created before presenting it to a host Creating DR groups optional If you want fo replicate virtual disks remotely create DR groups in the Data Replication folder For more information about DR groups see the HP Command View EVA online help or HP StorageWorks Continuous Access EVA administrator guide 24 Managing your storage environment Maintaining arrays This section describes how to use HP Command View EVA to maintain the arrays Updating the controller software For information about updating
