To Prepare a T3 Storage Device

Steps

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.
