9 2 Configuring Remote connectivity must be configured to contact EMC Customer Service or a third-party service provider for problem resolution assistance. This chapter identifies the software and related documentation to use to configure remote connectivity based on the type of system: VNX for block and legacy systems on page 10 VNX and VNX for file installations on page 11 VG2/VG8 installations on page 11 Problem Resolution Roadmap for VNX 7.0 9

10 Configuring VNX for block and legacy systems For VNX for block and legacy (CX, CX3, CX4, and AX4-5 series) systems, you can configure remote connectivity to contact EMC Customer Service or a third-party service provider for problem resolution assistance using the EMC Secure Remote Support (ESRS) IP Client for VNX communication infrastructure. Note: ESRS IP Client is the preferred remote connectivity and callhome agent for VNX, VNX for block, and VNX for file systems. To configure remote connectivity, use the following sequence and resources: 1. Use the information in the installation guide applicable to your system (VNX5100, VNX5300, VNX5500, VNX5700, or VNX7500) to physically connect your VNX for block system to your network. Each of the VNX installation guides also directs you to proceed with the Unisphere Installation Utility software and ESRS IP Client for VNX software on the VNX Installation Toolbox CD. For similar information about legacy systems, refer to the CLARiiON Interactive Installation Guide CD. Note: The ESRS IP Client for VNX software on the VNX Installation Toolbox CD supersedes and should be used instead of the ESRS IP Client for CLARiiON software on the CLARiiON Interactive Installation Guide CD. 2. Use the Unisphere Initialization Utility software and online help to register VNX for block components, such as HBAs, and assign IP addresses to the storage processors, and to attach hosts. For similar information about legacy systems, refer to the CLARiiON Interactive Installation Guide CD. 3. Use the EMC Secure Remote Support IP Client for VNX Requirements and Installation document to install the ESRS IP Client for VNX software on a monitor station. This document describes the ESRS IP Client for VNX. It also describes the regtool CLI utility and how to use it. 4. Use the ESRS IP Client for VNX software and online help to configure remote access to both VNX for block and legacy systems by means of the monitor station. Note: Configuring home to contact EMC Customer Service or a third-party service provider without using the ESRS IP Client for VNX communication infrastructure requires service involvement. Remote connectivity using a dial-up modem is not recommended and its setup requires a RPQ process. Remote connectivity using FTP is not supported on VNX for block or legacy systems. EMC recommends using the ESRS communication infrastructure that can be automatically installed on the monitor station. 10 Problem Resolution Roadmap for VNX 7.0

11 Configuring VNX and VNX for file installations For VNX and VNX for file installations, you can configure remote connectivity using EMC Secure Remote Support (ESRS) IP Client for VNX, , or FTP to contact EMC Customer Service or a third-party service provider for problem resolution assistance. Note: ESRS IP Client is the preferred remote connectivity and callhome agent for VNX, VNX for block, and VNX for file systems. To configure remote connectivity, use the following sequence and resources: 1. Use the information in the installation guide applicable to your platform (VNX5300, VNX5500, VNX5700, or VNX7500) to physically connect to your network. Each installation guide also directs you to proceed with the VNX Installation Assistant software and ESRS IP Client for VNX software that is on the VNX Installation Toolbox CD. 2. Use the VNX Installation Assistant software and online help to enable/configure home connectivity (IP address of SMTP server for file). The related Configure ConnectHome support online help refers to using Unisphere both to change home connectivity and to manage ConnectHome, and also refers to the Configuring Events and Notifications on VNX for File technical module for more information. The Getting Started Guide for the VNX Installation Assistant directs you to install and configure the EMC ESRS IP Client for VNX. 3. Use Unisphere's online help to manage ConnectHome, which is used to configure Monitor station HTTPS, , FTP, and modem for remote access. You can also use the VNX for file CLI for this purpose. 4. Use the EMC Secure Remote Support IP Client for VNX Requirements and Installation document to install the ESRS IP Client for VNX software on a monitor station. This document describes the ESRS IP Client for VNX. It also describes the regtool CLI utility and how to use it. 5. Use the ESRS IP Client for VNX software and online help to configure remote access to the file systems by means of the monitor station. Note: Although remote connectivity using a dial-up modem is supported, it is not recommended and its setup requires a RPQ process. EMC recommends using the ESRS communication infrastructure that can be automatically installed on the monitor station. VG2/VG8 installations Only trained EMC or EMC partner personnel should install and configure a VG2/VG8 gateway configuration. This includes the setup of remote connectivity to contact EMC Customer Service or a third-party service provider for problem resolution assistance. VNX and VNX for file installations 11

12 Configuring Note: ESRS IP Gateway 2.0 or later is supported as a remote connectivity and callhome solution for a VG2/VG8 gateway configuration; ESRS Gateway 1.x is not supported. 12 Problem Resolution Roadmap for VNX 7.0

14 Reporting EMC Secure Remote Support IP Client for VNX When you install the EMC Secure Remote Support (ESRS) IP Client for VNX, hereafter referred to in this document as ESRS IP Client for VNX, software on a monitor station, it monitors the operation of VNX for block and legacy (CX, CX3, CX4, and AX4-5 series) systems you specify for error events and automatically notifies your service provider of error events. It also provides a path for your service provider to use to securely connect to your monitored VNX for block and legacy systems. For VNX for file, the control station generates ConnectHome notifications for the associated system. When you install the ESRS IP Client for VNX software, it allows you to specify control stations that can connect to the monitor station and send ConnectHome notifications to your service provider. This software also provides a path for your service provider to use to securely connect to your specified VNX for file system through the associated control station. When you install the ESRS IP Client for VNX software, the ConnectHome information on the specified control stations is automatically configured. The , FTP, and Modem options are disabled when the Monitoring Station HTTPS option is enabled. In this case the ESRS IP Client for VNX communication infrastructure is used as the transport mechanism. During installation of the ESRS IP Client for VNX software, you also provide the necessary information for a contact person at your company who can answer technical questions and provide status information.

Client application and release level Tunable parameters For Windows applications, the release level is generally available from the Help About feature. For Data Mover parameters, use this command syntax: cat /nas/server/slot_<x>/param where: <x> = the Data Mover number. For global VNX for file parameters, type: cat /nas/site/slot_param VNX for file problem information For problems with Unisphere or the VNX for file, EMC recommends that before contacting the service provider or EMC for help, run log collection promptly. The sooner the collection script is run, the more likely that command output, logs, and dump files that can help correct the problem can be collected. The tasks for collecting problem information are: Run Log Collection and Automatic Transfer from Unisphere on page 20 Run Log Collection from the CLI on page 21 Use CLI options to perform script operations on page 24 details the command options available to perform script operations for VNX for file. Automatically collect and transfer logs The Automatic Collection and Transfer tool aids in troubleshooting and resolving system errors and other problems with the VNX for file that are configured to issue a call home. When VNX for file services are running, the collection script automatically runs in the background on the Control Station when needed to collect command output, logs, and dump 18 Problem Resolution Roadmap for VNX 7.0

19 Reporting files related to events that produce a CallHome. Examples of such events include Data Mover panics and Replication session failures. Note: As the script does not run during system installations and upgrades, it does not collect events that might occur during those operations. The tool produces zipped archive files of logs needed to analyze issues, and writes these files to /nas/var/emcsupport. This tool also collects Data Mover panic dumps when they occur with support materials. The Data Mover panic dumps are stored in the directory /nas/var/dump. After collecting logs and files, if the transfer script is enabled, the tool automatically transfers the collected data to EMC by using the configured transport mode (such as Monitoring Station HTTPS). By default, the transfer capability is disabled. A maximum of 460 MB is used for archiving log collections and a maximum of two Data Mover panic dumps. If the logs and dumps specified in the configuration file have reached the maximum, the tool deletes the oldest log to make room for new logs. However, the tool leaves old dumps in place, so those have to be manually deleted from the dump directory. When the tool successfully transfers a Data Mover panic dump to /nas/var/dump, it automatically clears the dump partition. If two dumps already exist in the dump area, the tool logs a message to sys_log, indicating that it cannot extract any further dumps to /nas/var/dump until unneeded dumps are manually deleted. The system logs contain entries each time a dump is transferred by the configured transport mode to EMC Customer Service. If the tool is invoked manually, the command output and any other important messages are logged in /nas/log/sys_log. Note: If the configuration file has used the entire serial number string to identify dumps, the location of the dump transfer might be truncated in sys_log. If this occurs, even though the system log might not report the complete transfer location, the transfer is successful, as recorded in the log. Administrator or root user privileges are needed to invoke the Automatic Collection and Transfer tool, which is run from the command line interface (CLI). You also might be asked by an EMC Customer Support Representative to run the tool to diagnose and solve system problems. Configuration file The first time the master script runs, it creates the configuration file /nas/site/automaticcollection.cfg. This file contains lines that set various parameters to manage the collection and transfer processes. For instance, it determines the location from which the files are transferred, and, in the case of FTP as the configured transport mode, it automatically sets the username and password for transfer files if the automatic transfer capability is enabled. If the configuration file is changed, the automatic collection script does not re-create it. In this case, to return to the default configuration file, rename or remove the edited configuration file from the system. However, apart from disabling the tool or changing the part of the file related to the transport mode configuration, EMC strongly recommends that you use the default values in this file. VNX for file problem information 19

20 Reporting Otherwise, it is possible that the tool could consume more Control Station resources than are necessary. The configuration file manages the following information: Whether to disable the automatic transfer capability. The number of dumps to retain in the /nas/var/dump directory. The default is 2. Indicates the current version of the tool. The number of simultaneous transfers allowed from the Control Station. The default is 2. The host IP address or URL for the configured transport mode of files. For FTP as the configured transport mode, the username and password of the administrator responsible for using the tool to transfer the files manually. For FTP as the configured transport mode, the remote directory for the FTP of files. Run Log Collection and Automatic Transfer from Unisphere The Log Collection and Automatic Transfer tool is a support feature in VNX for file. Log Collection is enabled by default. The system automatically collects and compresses logs and dumps when certain events are generated. Support materials, logs, and dumps are saved locally on the Control Station. You can also initiate on-demand log collection. In this case, only log information is collected. To initiate on-demand log collection: 1. Select the system. 2. Under Service Tasks, select Manage Log Collection. 3. In the dialog box that appears, click Collect. After collecting logs and files, you can configure the system to automatically transfer the collected data to EMC. The Automatic Transfer option is disabled by default. When you enable Automatic Transfer, the system will automatically transfer the support materials collected both logs and dumps from the Control Station to a preconfigured transport mode, such as FTP or Monitoring Station HTTPS. To enable automatic transfer: 1. Select the system. 2. Under Service Tasks, select Manage Log Collection. 3. In the dialog box that appears. select Enable Automatic Transfer and click Apply. 20 Problem Resolution Roadmap for VNX 7.0

21 Reporting Run Log Collection from the CLI You might be asked by an EMC Customer Support Representative to run the automatic collection script on the Control Station. To run the log collection script to create the support materials file, perform the following: 1. Log in to the control station as nasadmin and then switch (su) to root. 2. To run the script, type the complete path: Select /nas/tools/automaticcollection -getlogs 3. The script compiles the VNX for file support information into a compressed file and saves the file in the /nas/var/log directory. The file is given the name: support_materials_<serial number>.<yymmdd_hhss>.zip where: <serial number> = the serial number of the VNX for file. <yymmdd_hhss> = the date and the time the script was run. After creating the support materials file, contact the service provider or the EMC Customer Service Center for directions on how to deliver the file for analysis. Use CLI options to perform script operations on page 24 describes how to use the CLI options to perform several script operations. Disable Automatic Collection and Transfer tool To completely disable the Automatic Collection and Transfer tool, type: $/nas/tools/automaticcollection -disable -all An alternative method of disabling the entire tool is to edit the configuration file /nas/site/automaticcollection.cfg using a text editor such as vi, and uncomment the line containing the word OFF. The following is an example of a configuration file output: VNX for file problem information 21
