How to increase the filesystem size in HACMP.
what is the difference between normal chfs command and increase the filesystem size in HACMP.

The difference is: you have 2 (or more) machines in a cluster but only one of them has access to the filesystems at a time. If you change the filesystem you have to make sure that not only this one machine but ALL machines in the cluster get this information and update their bookkeeping data.

"chfs" is changing the filesystem on one machine and updating this bookkeeping data (in the ODM) accordingly. This is - for reasons stated aboce - not sufficient.

I hope this helps.

You can find 'CSPOC' option in "smitty hacmp".
Through this you can increase the filesystem, and this will take care of updating ODM entries and timestamp of the filesystem in all the nodes of the cluster.
