Will all data on the disks show under new controllers (with the same fw)? Will host presentation be also transferes?<BR />I’m not sure if metadata on disk contains all the necessary information to transfer disk shelfs between two controller shelfs<BR /> Fri, 03 Sep 2010 08:19:08 GMT https://community.hpe.com/t5/disk-enclosures/replacing-controller-enclousure-eva4400/m-p/4682895#M35795 daanj 2010-09-03T08:19:08Z https://community.hpe.com/t5/disk-enclosures/replacing-controller-enclousure-eva4400/m-p/4682896#M35796 hello, it should work, but I suggest to do such replacement by HP technician...<BR /><BR />Jan Fri, 03 Sep 2010 18:11:23 GMT https://community.hpe.com/t5/disk-enclosures/replacing-controller-enclousure-eva4400/m-p/4682896#M35796 Jan Soska 2010-09-03T18:11:23Z https://community.hpe.com/t5/disk-enclosures/replacing-controller-enclousure-eva4400/m-p/4682897#M35797 Hmmm, why you need a new controller enclosure?

Now it's recommended that an HP tech must do the work Mon, 06 Sep 2010 11:10:53 GMT https://community.hpe.com/t5/disk-enclosures/replacing-controller-enclousure-eva4400/m-p/4682898#M35798 Oscar_Maimó 2010-09-06T11:10:53Z
