Jumpstart server setup - for SPARC client
Jumpstart installation method is CLI that enables automatic installation of the OS on remote systems.
It is using:
1. profile text file (defines software to be installed)
2. rules text file (defines rules/steps for install)
3. scripts for pre and post install tasks
4. sysidcfg (configuration information)
Note: Sun provides 'check' script that you run to verify rule file, if everything okay, script will generate rules.ok file.
Basically this works like:
1. Jumpstart reads rules.ok file
2. Jumpstart finds profile in rules.ok and use it for installation
3. If rule(s) doesn't match, regular interactive installation occurs.
Let's do some exercises and examples in creating Jumpstart server.
One machine will be use as Boot, Install and Profile server.
NOTE: this doc assumes client is SPARC, not x86 machine!
First you need Jumpstart directory that is accessible over network.
Say it is /jumpstart
Share it (add line to /etc/dfs/dfstab file)
share -F nfs -o ro,anon=0 -d "Jumpstart_Share" /jumpstart
Installing Jumpstart Server
Mount Solaris distribution (DVD or NFS location) and run command:
# /mnt/Solaris_10/Tools# ./setup_install_server /jumpstart/sparc
Verifying target directory...
Calculating the required disk space for the Solaris_10 product
Calculating space required for the installation boot image
Copying the CD image to disk...
Copying Install Boot Image hierarchy...
Copying /boot netboot hierarchy...
Install Server setup complete
SPARC client uses /etc/bootparams (located on the Jumpstart server) file to boot.
This file will be populated with clients using script add_install_client (located in same directory as setup_install_server script).
Example how file looks:
Example of the file – use & (logical AND) to join keywords/values in same rule:
And verify the rules file:
# rules keyword & values begin script profile finish script
hostname unixlab && arch sparc - profile finish_script
Note: check Sun docs for other rule's keywords/values.
/jumpstart/config/client_hostname # ./check
Validating profile profile...
The custom JumpStart configuration is ok.
Begin (Bourne shell) script
Here you place action to be performed before Solaris software is installed.
After installation, logs will be in /var/sadm/system/logs/begin.log
This file defines how to install software. Check Sun docs for many profiles' keywords/values.
Example of profile with comments:
# keyword value
# Keyword install_type is MANDATORY
# If system_type omitted, standalone will be also used
# Cluster is collection of packages that makes functional unit.
# Meta-cluster is collection of clusters and packages that creates configuration.
# They are listed in /mnt/Solaris_10/Product/.clustertoc file.
# If add/delete is not specified, add is used
cluster SUNWCdhcp add
cluster SUNWC-name add nfs server:/servername/path
# partitioning - Defines how disk is divided in slices
# Must be combined with keyword filesys
filesys rootdisk.s0 4096 /
filesys rootdisk.s1 4096 swap
filesys rootdisk.s3 4096 /var
filesys rootdisk.s4 4096 /usr
filesys rootdisk.s5 free /backup
filesys rootdisk.s7 256
# Creating SVM Mirror and State Database Replica
#filesys mirror:d10 c1t0d0s0 c1t1d0s0 4096 /
#filesys mirror c1t0d0s1 c1t1d0s1 4096 swap
#filesys mirror:d30 c1t0d0s3 c1t1d0s3 4096 /usr
#filesys mirror:d40 c1t0d0s4 c1t1d0s4 4096 /var
#filesys mirror:d50 c1t0d0s5 c1t1d0s5 free /backup
#metadb c1t0d0s7 count 3
#metadb c1t1d0s7 count 3
Finish (Bourne shell) script
This performs action after Solaris software is installed but before system reboots.
It's ideal for installing third party software, setting root's password, etc.
After installation, logs will be in /var/sadm/system/logs/finish.log
Note that file system remains mounted on /a until system reboots.
Required services on the Jumpstart server
Make sure that three necessary services are running on jumpstart server.
Server must be on same subnet as client, since client bootparam request packet has TTL=1 (can't cross gateway).
Also RARP doesn't transmit network/router information.
SPARC client installation
See the link how to add SPARC client to Jumpstart server.
Then go to the OpenBoot (ok) prompt and boot from network:
ok boot net -v - install
- more info to be added later?!
