Well i reported this issue yesterday. Today they still didn't have a solution. That's why i started to replicate the problem over to another lun, to see what was going to happen. After de succeeded test, we decided to go for it, and replaced the disk of the MetaLUN in question. The owner of the LUN changed immediately back to it's orginal owner and the status of the MetaLUN changed from shutdown to degraded. After the rebuilding, the MetaLUN was working again!
Last week one drive failed failed from a LUN which is contained in a MetaLUN. The drive in question was a 73GB. While we didn't have a 73GB spare in stock, we replaced it with a 146GB drive.The replaced drive did rebuild and all looked fine. UNTILL we restarted our CX-600 yesterday.   The MetaLUN doesn't come online, the displayed status says: shutdown. One of the MetaLUN compontents (1 out 4 LUNs) go owned. Apparently this is a problem in the flare version: CX200, CX400, CX600 LUNs may fail to assign (go  unowned) after a drive replacement, a hot spare  equalize where the hot spare is a different size than the  drive it replaced, and then a trespass to the peer SP.   (112437) Fixed in Revision: 02.07.010   Solution:  Correct defect in code that determines the  rebuild checkpoint following drive replacement. What to do?  Can i change the drive in question with a 73GB spare, without losing anything..?Does al start working again? Thanks for helping!
