Extend logical volume on AIX 5.3

Today i extented an logical volume and filesystem on AIX 5.3

The following steps i had to do:

- create new LUN on storage
- run cfgmgr on target host to find new LUN as disk
- run smit and extend number of physical volumes for the logical volume
- run extendlv NAME_OF_LV SIZE_TO_EXTENT
+ here it was: "extendlv dbtest 20G" for new 20 gigabyte space
- run chfs -a size=+20480M to extend the filesystem
+ chfs requires 72 minutes to do the job, while there was no I/O on the filesystem
