New CLI in Sun Cluster 3.2

Coming Sun Cluster 3.2 will see new set of commands.
No. This doesn't mean that old set of commands like 'scstat', scsetup, 'scrgadm' will not be available.
It will still be present. But 3.2 introduces new commands which are CLIP complaint.

Some of the main drawback of existing command sets are
1) Few commands and lots of options to remember.
2) Commands are not intiutive.
3) Confusing error messages.
4) It is not complaint to CLIP.

The new command set address all these issues.

The new command set has following features
1) Object Oriented Design
2) Reuseable configuration spefication
3) Initiutive and consistent subcommands.
4) Each object operates on one cluster object
5) consistent error code and error messages.

So what are these new commands ???
    There is whole list of commands. The best part as I said is it is intuitive.
All the command starts with 'cl'
The path is same '/usr/cluster/bin'
1) 'cluster' to know more about cluster.
    For example: 'cluster status' is equivalent to 'scstat'.
2) If you want to perform any operation quorum then use 'clquorum'
3) For operations on resources use 'clresource'
4) For operations on resourcegroup use 'clresourcegroup'

so on...
I will try to blog about more about new cli later and its usage for regular cluster adminstration purpose.
