Question : cannot detect newly added LUNS in powermt

Host server is RHEL 4

Server have storage LUNS already and mounted.
Now storage team added new LUNS and its visible to OS now. I can see new LUNS in /proc/scsi file

But its not visible when i run powermt display dev=all (ie logical deviced are not converted to powermt devices /  Pseudo devices)

Do I need to run below command

 #powermt config  

Do I need to umount all filesystem before running this command ?

Answer : cannot detect newly added LUNS in powermt

OK, I can give you the general design pattern here.

For generating the language checkboxes on the page, you want to have a table that lists all the languages.  You can get the ISO standard list here.  It is a big list.  Keep what you need.  You might have two columns in the list - the ISO639-2 code in one column and the English language name in the other column.
http://www.loc.gov/standards/iso639-2/php/code_list.php

To generate the checkboxes, you SELECT * from the languages table and iterate over that results set.  Use the ISO639-2 code for the value of the checkbox and language[] for the name of the checkbox.

When the form is submitted, the only checkboxes that are present in the $_POST array are the ones that are checked.  They will be in the languages sub-array of the $_POST array.

So in your action script, you would iterate over the POST languages sub-array and do INSERT statements into the pivot table.

To sum up, there are three tables for this part of the app - `languages`, `pivot`, and `persons`  You would index languages on the ISO639 code, persons on the auto_increment id, and pivot on both the language code and the persons id.
