3.2 Jump-Starting the Servers

Use the following procedures to prepare for jump-starting the servers and configuring them afterwards. Jump-starting a server reinstalls the operating system and file system on a server, obliterating any old files. Before you begin, create a list of all servers with their MAC address, IP address and hostname for each one. Group the servers in the following categories:

• Front-end (FE) servers

• FE servers with Message Transfer Agent (MTA)

• Back-end (BE) servers

• Administration station

• Backup server

Then initialize the management station as follows:

• Add the MAC address of all servers to /etc/ethers.

• Add the IP address and hostname of all servers to /etc/hosts.

For each server, you must perform the following preparation according to the server category, and you must jump-start the server before configuring the next one. The configuration of the server afterwards may be performed immediately after jump-starting or after all servers have been jump-started.

To Prepare and Jump-Start a Server

Steps

1. Log into the puppet web interface at https://puppetServer.domain:6364/config.

2. Select the Advanced Client link. On the Advanced Client page, enter the hostname of the server to jump-start, and press Enter. The server's MAC address should automatically be entered in the Ethernet Address field. Fill in the other fields as follows:

   • Machine Type: sun4u

   • Boot Image: sparc-sunos5.9_u7

   • Model Configuration: for a BE server, select PSC_META, for all others select FE_PSC_META

   Click Add when all fields are complete.

3. Click on Update Screen, and then on Verify Configuration. In the next screen, click on Commit Changes, and then on Go Back.

4. Under Base Jumpstart Profile, select the profile corresponding to the type of server:

   • For a BE server, select req_BE+_rootdisk

   • For a FE server, select req_FE+_rootdisk

   • For a FEMTA server, select req_FEMTA+_rootdisk

   • For the administration station, select all_AW+_rootdisk

   • For the backup server, select req_BACKUP+_rootdisk

5. Make sure the sysidbase value is set to DEFAULT.

6. Click on Verify Configuration, then on Commit Changes. Now click Go Back and Fetch Current Configuration.

7. Review the profile and if everything is correct, click on Verify Configuration. The next screen will reconfirm the information, with different models for different server types:

   Hostname serverName Ethernet Address 0:3:cd:aa:d7:21 Boot Method bootp Puppet Platform sparc-sunos5.9 Install Image sparc-sunos5.9_u7 Picked Models PSC_META Expanded Models server server:std-server200501 std-server200501:psc-JES- model200501 std-server200501:psc-cluster-model200501 std-server200501:psc- model200501 std-server200501:psc-vts200501 std-server200501:san44-model200501 SunOS: Profile req_BE+_rootdisk SunOS: sysidcfg(s) base: DEFAULT

8. Click Commit Changes one last time and verify that there are no errors in the configuration. The next screen summarized the actions of the configurator:

   Puppet: Begin Installation Configuration * Puppet: Client configuration written * SunOS: profile written. * SunOS: sysidcfg written. * SunOS: bootenv.rc written. * SunOS: rules written. * SunOS: SI_CONFIG_DIR/rules re-built. * SunOS: passed quickcheck. * Puppet: OS Driver passed Puppet: End Installation Configuration

9. Connect to the console port of the server to be jump-started and enter the following command:

   ok> boot net - install

10. After the server has rebooted, follow the configuration procedure for the type of server:

    • To Configure a BE Server After Jump-Start

    • To Configure a FE or Backup Server After Jump-Start

    • To Configure a FE-MTA After Jump-Start

    • To Configure the Administration Station After Jump-Start

To Configure a BE Server After Jump-Start

Steps

1. Edit the prompt in the /.profile for root:

   PS1="`tput bold``/usr/ucb/whoami`@`uname -n`:#`tput sgr0` "

2. Restore the contents of /var/bits with the following commands:

   # cd /var # gzcat bits/bits.tar.gz | tar xf -

3. Change ownership of home directories with the following commands:

   # cd /home # for I in `ls` > do > chown $I $I > done # cd /

4. Once the system is on the corporate network, edit /etc/passwd and /etc/user_attr to put root back as a role.

5. Add the cluster to the path:

   PATH=/usr/bin:/usr/sbin:/usr/ucb:/usr/ccs/bin:/usr/cluster/bin:$PATH

   Also, add the cluster to the path in the /.cshrc file for root:

   set path=( /usr/bin /usr/sbin /usr/ccs/bin /usr/cluster/bin $path )

6. Create additional metadbs with the following command:

   metadb -a -c 3 /dev/dsk/c1t1d0s7 /dev/dsk/c1t2d0s7 /dev/dsk/c1t3d0s7

7. Create mirrors of /globaldevices and /var/crash. This requires several commands, some of which depend on which node of the cluster the server belongs to.

   1. Unmount the file systems with the following commands:

      • On all servers regardless of cluster node:

        umount /globaldevices umount /var/crash newfs -v -i 1024 /dev/rdsk/c1t0d0s3 metainit -f d106 1 1 c1t2d0s0 metainit -f d206 1 1 c1t3d0s0 metainit -f d6 -m d106

      • On servers in cluster node 1:

        metainit -f d103 1 1 c1t0d0s3 metainit -f d203 1 1 c1t1d0s3 metainit -f d3 -m d103

      • On servers in cluster node 2:

        metainit -f d113 1 1 c1t0d0s3 metainit -f d213 1 1 c1t1d0s3 metainit -f d13 -m d113

   2. Then edit the /etc/vfstab file:

      • On all servers regardless of cluster node, comment out the entries for /globaldevices and /var/crash. Then add the following line:

        /dev/md/dsk/d6 /dev/md/rdsk/d6 /var/crash ufs 2 yes logging

      • On servers in cluster node 1, add the following line:

        /dev/md/dsk/d3 /dev/md/rdsk/d3 /globaldevices ufs 2

      • On servers in cluster node 2, add the following line:

        /dev/md/dsk/d13 /dev/md/rdsk/d13 /globaldevices ufs 2 yes logging

   3. Attach the submirrors with the following commands:

      • On all servers regardless of cluster node:

        mount /globaldevices mount /var/crash metattach d0 d200 metattach d6 d206

      • On servers in cluster node 1:

        metattach d3 d203

      • On servers in cluster node 2:

        metattach d13 d213
