SnapProtect^™ Backup - EMC Clariion, VNX

Pre-Requisites

Licenses

• Clariion SnapView and AccessLogix licenses for Snap and Clone.
• SYMAPI Feature: BASE/Symmetrix license required to discover Clariion storage systems.

You can use the following command to check the licenses on the host computer:

C:\SYMAPI\Config> type symapi_licenses.dat

Array Software

• EMC Solutions Enabler (6.5.1 or higher) installed on the client and proxy computers.

  Client Components (SYMCLI) are required only during the initial one-time configuration. Base Components (with SYMAPI) are necessary and required for all snap operations.

• Navisphere CLI and NaviAgent installed on the client and proxy computers.
• If AccessLogix is not enabled, go to the Navisphere GUI, right-click EMC Clariion Storage System and click Properties. From the Data Access tab, select Enable AccessLogix.
• Clariion storage system should have run successfully through the Navisphere Storage-System Initialization Utility prior to running any Navisphere functionality.
• Ensure enough reserved volumes are configured for SnapView/Snap to work properly.

For EMC VNX:

• EMC Solutions Enabler (7.2 or higher) installed on the client and proxy computers.

  Client Components (SYMCLI) are required only during the initial one-time configuration. Base Components (with SYMAPI) are necessary and required for all snap operations.

• Navisphere CLI and Navisphere/Unisphere Host Agent installed on the client and proxy computers.
• VNX storage system should have run successfully through the Unisphere Storage-System Initialization Utility prior to running any Unisphere functionality.

Setup the EMC Clariion

1. Create a RAID group
2. Bind the LUN
3. Create a Storage Group
4. Register the client computer (covered by installing NaviAgent)
5. Map the LUNs to the client computer where the NaviAgent resides
6. Reserved/Clone volumes target properly for SnapView

For example, as shown in the image on the right, the Clariion ID of APM00033400899 has the following configuration: a RAID Group 0 provisioned as a RAID-5 group (Fiber Channel drives) LUNs are mapped to Storage Group SG_EMCSnapInt1 with LUN ID of #154 present to client computer emcsnapint1. The example shows the serial number of LUN 154: RAID Group: RAID Group 0, containing 3 physical disks Storage Group: currently visible to a single client computer LUN is shown as a Fiber Channel device The devices under LUN 154 reside on RAID Group 0 which has RAID-5 configuration.

Authenticate Calypso user information for the Naviagent

Follow the steps below to specify the authorization information for EMC Solutions Enabler and Navishphere CLI to ensure administrator access to the Navisphere server.

1. To set the authorize information, run the symcfg authorization command for both the storage processors. For example:

   /opt/emc/SYMCLI/V6.5.3/bin# ./symcfg authorization add -host <clariion SPA IP> -username admin -password password

   /opt/emc/SYMCLI/V6.5.3/bin# ./symcfg authorization add -host <clariion SPB IP> -username admin -password password

2. Run the following command to ensure that the Clariion database is successfully loaded.

   symcfg discover -clariion -file AsstDiscoFile

   where AsstDiscoFile is the fully qualified path of a user-created file containing the host name or IP address of each targeted Clariion array. This file should contain one array per line.
3. Create a Navisphere user account on the storage system. For example:

   /opt/Navisphere/bin# ./naviseccli -AddUserSecurity -Address <clariion SPA IP> -Scope 0 -User admin -Password password

   /opt/Navisphere/bin# ./naviseccli -AddUserSecurity -Address <clariion SPB IP> -Scope 0 -User admin -Password password

4. Restart the NaviAgent service.
5. Run snapview command from the command line to ensure that the setup is ready.

On Unix computers, you might need to add the Calypso user to the agent.config file.

Setup the Array Information

Provide the identification information for the array to ensure access. The following section provides step-by-step instructions for setting the array information.

1.	From the CommCell Console, navigate to Tools | Control Panel. Click Array Management.
2.	Click Add.
3.	Select EMC CLARiiON from the Snap Vendor list for both Clariion and VNX arrays. Specify the serial number of the array in the Name field.
	For reference purposes, the screenshot on the right shows the serial number for the EMC Clariion storage device.
4.	Enter the access information of a Navisphere user with administrative privileges in the Username and Password fields. Use the Description field to enter a description about the entity. This description can include information about the entity's content, cautionary notes, etc. Click OK to save the information.
