The following procedure requires that the target system and boot server must be on the same subnet.
See Chapter 5, Setting Up a Boot Server. for instructions on how to enable TFTP and RARP services on the boot server.
Become superuser on the boot server:
$ su Password: superuser_password # |
Copy the inetboot.sun4u file, that is, install_dir/chorus-usparc/opt/unsupported/inetboot.sun4u to the /tftpboot directory, where, the install_dir is /opt/SUNWconn/SEW/5.0-UltraSPARC.
Create a soft link from the inetboot.sun4u file to a file called /tftpboot/target_IP_address_in_hex.
For example, the file for the target system with IP address 129.157.197.88 is called 819DC558, and is constructed as follows:
129 in decimal translates to 81 in hexadecimal
157 in decimal translates to 9D in hexadecimal
197 in decimal translates to C5 in hexadecimal
88 in decimal translates to 58 in hexadecimal
To create the soft link for the preceding examples, use the following commandS:
# ln -s /tftpboot/inetboot.sun4u 819DC558 |
Create a /tftpboot/export/root/target/platform/sun4u directory on the boot server.
Copy the system image, chorus.obp, to the directory you just created.
Edit /etc/bootparams to include the following:
target root=boot_server:/tftpboot/export/root/target
where target is the target system hostname and boot_server is the boot server hostname.
Create the bootparams file if it doesn't exist.
Edit /etc/hosts to include the following:
target_IP_address target
where target_IP_address is the target IP address (such as 129.157.197.88) and target is the target system hostname.
Edit /etc/ethers to include the following:
target_Ethernet_address target
where target_Ethernet_address is the target Ethernet address (such as 8:0:20:a7:d6:f3) and target is the target system hostname.
Edit /etc/dfs/dfstab to include the following:
share -F nfs -o rw -d "ChorusOS boot" /export/home
For the directory to be shared, you must stop and then restart the NFS server on the host workstation as follows:
$ su Password: superuser_password # /etc/init.d/nfs.server stop # /etc/init.d/nfs.server start |
Edit /etc/nsswitch.conf so that the hosts, ethers, and bootparams entries read files, rather than NIS databases. For example:
# # /etc/nsswitch.nis: # # An example file that could be copied over to /etc/nsswitch.conf; it # uses NIS (YP) in conjunction with files. # # "hosts:" and "services:" in this file are used only if the # /etc/netconfig file has a "-" for nametoaddr_libs of "inet" transports. # the next two lines obviate the "+" entry in /etc/passwd and /etc/group. passwd: files nis group: files nis # consult /etc "files" only if nis is down. hosts: files [NOTFOUND=return] nis networks: nis [NOTFOUND=return] files protocols: nis [NOTFOUND=return] files rpc: nis [NOTFOUND=return] files ethers: files [NOTFOUND=return] nis netmasks: nis [NOTFOUND=return] files bootparams: files [NOTFOUND=return] nis publickey: nis [NOTFOUND=return] files netgroup: nis automount: files nis aliases: files nis # for efficient getservbyname() avoid nis services: files nis sendmailvars: files
Reboot the boot server.
