Here is the example:
/u01/,/u02/,/u03/,/u04/ - 4 LUNS from EMC
/u05,/u06/,/u07,/u08/,/u09,/u10 - 6 LUNS from HP
all having same size.
The plan is to temporary move out the datafile from file system to temp storage and destroy the existing mountpoint, then reuse/assign these 10 LUNS into a single diskgroup.
Would like to know the feasibility of doing this. Thanks
First if you can create new LUNS then you can just migrate from non-ASM to ASM.
Have the same type of LUNS is the best practice I have seen performance issue where mixed IOPS speeds for different LUNS causing problems. The LUNS size is a must they SHOULD be the same size always if you where going to move lets say from 50G LUNS to 100G then you could temporarily add the 100G LUNS then remove to 50G LUNS but you would never mix the different size of LUNS in one diskgroup.
let me know if this helps.
