Configuring StorEdge 3900 or 6900 Series Systems in a Running Cluster

You can customize the configuration of the logical unit numbers (LUNs) on the StorEdge T3+ arrays in your StorEdge 3900 or 6900 Series system, using the system's menu-driven or command-line interface. The Sun StorEdge 3900 and 6900 Series Reference Manual describes the factory default settings for the StorEdge T3+ arrays in the StorEdge 3900 and 6900 Series systems.

For StorEdge 6900 Series systems only, you can also customize the configuration of the virtual LUNs (VLUNs) on the virtualization engines in the system, using the system's menu-driven or command-line interface. The Sun StorEdge 3900 and 6900 Series Reference Manual describes the factory default settings for the virtualization engines in the StorEdge 6900 Series systems.

How to Configure LUNs on the Arrays in Your StorEdge 3900 or 6900 Series System

A summary of the steps used to configure the LUNs, or logical volumes, on the StorEdge T3+ arrays in your StorEdge 3900 or 6900 system is listed below.

• If you are using the menu-driven interface, perform the following steps.

  1. On the storage service processor (SSP), start the Configuration Utilities using the runsecfg command.

  2. Select T3+ Configuration Utility from the main menu.

  3. Enter your StorEdge T3+ array password when you are prompted.

  4. Step through the submenus to configure the StorEdge T3+ arrays. See the Sun StorEdge 3900 and 6900 Series Reference Manual for more information about the submenus.

• If you are using the command-line interface, perform the following steps.

  1. On the SSP, enter your StorEdge T3+ array password (if prompted to do so).

  2. Use the SSP StorEdge T3+ array commands to configure the arrays in your system. See the Sun StorEdge 3900 and 6900 Series Reference Manual and the man pages for these commands for more information.

How to Configure VLUNs on the Virtualization Engines in Your StorEdge 6900 Series System

The Sun StorEdge 6900 Series systems' virtualization engines allow you to divide StorEdge T3+ array LUNs into small virtual LUNs (VLUNs) for more customized storage usage, such as in a storage area network (SAN).

A summary of the steps used to configure the VLUNs on the virtualization engines in your StorEdge 6900 system is listed below.

• If you are using the menu-driven interface, perform the following steps.

  1. On the SSP, start the Configuration Utilities using the runsecfg command.

  2. Select VE Configuration Utility from the main menu.

  3. Step through the submenus to configure the virtualization engines. See the Sun StorEdge 3900 and 6900 Series Reference Manual for more information about the submenus.

  4. After you configure the VLUNs, from any cluster node use the scgdevs command to update the global device IDs.

     # scgdevs

  5. On one node connected to the partner-group, use the format command to label the new VLUNs.

     # format

     See the format command man page for more information about using the command.

• If you are using the command-line interface, perform the following steps.

  1. Use the SSP virtualization engine commands to configure the virtualization engines in your system. See the Sun StorEdge 3900 and 6900 Series Reference Manual and the man pages for these commands for more information.

  2. After you configure the VLUNs, from any cluster node use the scgdevs command to update the global device IDs.

     # scgdevs

  3. On one node connected to the partner-group, use the format command to label the new VLUNs.

     # format

     See the format command man page for more information about using the command.
