.::: How to Check Host ID, UUID on Solaris & Check Solaris Version :::.

1. Check Host ID Solaris

The Hostid is a globally unique ID for a Sun Solaris Machine. Sometimes, you need to change this hostid for whatever purpose. For example, you current machine is down for hardware failure and you purchased a new machine.

However, all your current running software are based on this old hostid, and you must bring the new machine up within a very short time. The quick solution is to change the new machine’s hostid to be as same as the old one.

root@teguht # showrev

Hostname: teguht

Hostid: cd1628b

Release: 5.10

Kernel architecture: i86pc

Application architecture: i386

Hardware provider:

Domain:

Kernel version: SunOS 5.10 Generic_147148-26

root@teguht # hostid

0cd1628b

root@teguht #

Note : You can change hostid solaris detail how to change hostid solaris 10

2. Check UUID (Universally Unique Identifier) Solaris

UUID is a Universally Unique IDentifier. It's a identification code given to each storage device you have on your system, aimed to help you uniquely identify each device no matter what.

UUIDs can be used to identify DVD drives, removable media (USB flashsticks) and each partition on any of your hard drives. UUID is a pretty long hexadecimal string, for example:

564dd8ab-e2d5-7d79-d965-9232c053d603

UUID is the only way to guarantee you recognize the same drive or partition no matter what. For example, if you introduce to your system another hard drive, this might upset quite a few things, starting with the way your system boots up (or stops booting up upon the new drive introduction). Using UUID helps remedy most of such things.

Automatically assigned device names in your system are not consistent, they are according to the order of loading the kernel modules up during (most usually) the startup time, and thus the names will look different if you boot with one of your USB flashsticks attached and then reboot after you plug it out.

 UUIDs really useful for mounting  removable media : you can use UUID to always mount the same card at the same location.

3. Check Solaris update version

root@teguht # cat /etc/release

root@teguht # more /etc/release
