T3 Storage Devices

This section provides the procedures for preparing T3 devices for Sun Management Center 3.5, and procedures for removing T3 device configuration data from existing Sun Management Center 2.x or Sun Management Center 3.x installations.

T3 device configuration data must be removed from existing Sun Management Center installations before you can upgrade to Sun Management Center 3.5.

Preparing a T3 Storage Device

Before you install and set up the Sun Management Center T3 Add-on, you must modify the /etc/hosts and /etc/ethers files on the system where the Sun Management Center add-on Monitoring and Management of A5x00 and T3 Devices is to be installed.

The following procedure assumes that you have installed and configured the T3 storage device as described by the Sun StorEdge T3 Disk Tray Installation, Operation, and Service Manual.

When the /etc/hosts and /etc/ethers files have been updated on the machine where the Sun Management Center add-on Monitoring and Management of A5X00 and T3 Devices will be installed, you can proceed with installing and setting up the T3 add-on.

To Prepare a T3 Storage Device

1. Determine the IP address and ethernet address for each T3 storage device.

   Open a terminal window and type the command arp t3-device-name where t3-device-name is the name of the T3 storage device. For example:

   # arp T3-001 T3-001 (10.100.20.300) at 1:2:30:ab:ba:45 permanent published

   In the above example, 10.100.20.300 is the IP address, and 1:2:30:ab:ba:45 is the Ethernet address of the T3 storage device T3-001.

2. Repeat Step 1 for each T3 device on your network.

   When you have recorded the IP address, Ethernet address, and name for each T3, go to the next step.

3. Log in as root on the machine where you will install the Sun Management Center add-on Monitoring and Management of A5X00 and T3 Devices.

   This machine can be either the machine where you install the Sun Management Center server or the machine that you have allocated as dedicated platform agent server.

4. Record each T3 IP address and name in the /etc/hosts file.

   For example, assume that three T3 devices are attached to your network. Assume that you used the arp command to determine the IP address, and Ethernet address of each T3 device, and recorded the information as follows:

   storage-t3–1	172.16.100.10	0:20:f2:0:59:48
   storage-t3–2	172.16.100.11	0:20:f2:0:5f:40
   storage-t3–3	172.16.100.12	0:20:f2:0:7f:a8

   The entries in the server /etc/hosts file would then be as follows:

   172.16.100.10   storage-t3–1
   172.16.100.11   storage-t3–2
   172.16.100.12  storage-t3–3

5. Record each T3 storage device Ethernet address and name in the /etc/ethers file.

   Create the /etc/ethers file if the file does not already exist.

   Using the example given in Step 4, the entries in the server /etc/ethers file would then be as follows:

   0:20:f2:0:59:48   storage-t3–1
   0:20:f2:0:5f:40   storage-t3–2
   0:20:f2:0:7f:a8  storage-t3–3

   ---

   Caution –

   If you include the domain name as part of the T3 device name, make sure the domain name is identical in both the /etc/hosts and /etc/ethers files. The entries are case sensitive.

   ---

   For example, assume that the /etc/hosts file contains:

   0:20:f2:0:59:48   storage-t3–1.sun.com

   Also assume that the /etc/ethers files contains

   0:20:f2:0:59:48   storage-t3–1.Sun.Com

   In this example, the T3 storage device cannot be set up using the Sun Management Center setup tools because the domain name case is different.

Removing T3 Device Configuration If Present

If you monitor and manage T3 storage devices using the Monitoring and Management of A5x00 and T3 Devices add-on, remove T3 device configuration information before you uninstall Sun Management Center 2.x or Sun Management Center 3.x. The es-uninst command does not remove T3 device configuration information.

To Remove T3 Device Configuration

1. Log in as root by typing su - root on the machine where the Sun Management Center 2.x or Sun Management Center 3.x server is installed.

2. Stop the Sun Management Center agent.

   Type the command /opt/SUNWsymon/sbin/es-stop -a.

3. Run the pre-uninstall script to remove T3 device configuration information.

   Type the command /opt/SUNWsymon/addons/storage/sbin/pre-uninst.sh.

   You are asked if you want to stop the T3 from sending syslog messages. Type y. You are then prompted for the root password for the T3 device. Type the password.

   You are notified that the T3 device has been removed from the T3 module.

   • If you do not run the pre-uninst.sh script before you install Sun Management Center 3.5, you will have to manually remove T3 configuration information before you can set up the new Sun Management Center 3.5 installation.

   • If you run the pre-uninst.sh script but then decide to keep your Sun Management Center 2.x or Sun Management Center 3.x installation, type /opt/SUNWsymon/es-setup -F to set up your T3 devices again.
