FastT700+EXP700 raid level

[rs6000er]

hi, all!
i have FastT700+EXP700, the raid level is raid 0.
i want to change the raid 0 to raid 5, the manual said i can change the raid level without stop the production servers. i cant get any information from ibm's web site. so if anyboby have some ideas about it.
OS - AIX 5.1
DB - Oracle 7.1.7
FSM - 8.3
Raid level - raid 0 (200 GB)

First off you do have to stop all I/O to that Lun. Then you need to go through Storage Manager and you can change the raid level. You may have to shutdown the server depending on what you have using that LUN.

i have read on manual - the fastt is capable of changing raid levels on the fly without interruption to the host as long as disk requirements are met.

Well ,
it was also said in manual that you can add new disks to exp700 online , but when we did , we lost a lun which included my Rollback segments Tablespace , and caused Oracle crash.

In my Manuals from the FAST-T class it says to change the raid level or add a disk you must stop all I/O to that LUN. If it is a database you can Quiesce the database or you must shut it down while doiong this
