Physically moving array from one MSA1500 to another.
Hi Folks:
I have to go to Japan and work on a server configuration. Both servers have MSA1500 array controllers. OS is Windows 2003 Server. The company has been evaluating one of our base server configurations for months and ended up buying it. Now they want to upgrade this base server to a a midrange server. Just means more array space and an aditional tape drive in the tape library and they've also bought the big brother, one of our high end systems. I've been told that they're not interested in any of the evalvation data they've collected during the beta test. This would be ideal, but I think it's famous last words. I suspect they may want to move the data from one system to the other. It could be up to a terabyte. And while we could do a tape backup and restore, this will take some time. It's millions of tiny files. My question is this? Is it really possible to move arrays from one system's MSA1500 to another systems's MSA1500 by moring whole drive shelves or individual drives and have the existing array recognized? Is this part of what HP means by "Adaptive Enterprise"? Everything just plugs into everything else and works. Or is "Adaptive Enterprise" just a grand marketing slogan? I should have time to test this on a small scale tomorrow, before my Thursday flight. Just figured I'd ask here to find out about others' experiences. Thanks, Dennis Herrick |

The MSA1500 does not have copy functions between arrays. Is this Or is "Adaptive Enterprise" just a grand marketing slogan? Yes. I should have time to test this on a small scale tomorrow, before my Thursday flight. Just figured I'd ask here to find out about others' experiences. You could attempt to shut down the original array, physically moving the disks in the configuration (doesn't have to be all disks, just those who take part of the LUN(s) you want to move. Plug the disks into the same locations in the target array and if everything works, the new MSA1500 should recognize the LUNs and you're ok. This could very well be supported actually, this is what HP calles DtS (DAS to SAN migration). The idea is to move storage behind internal server's smart array controllers to the MSA1500 (since the MSA1500 is a Smart array 5200 series controller). Risky, so of course take a backup. Another option is to use Symantec Storage Foundation to mirror the original volume(s) to newly created empty volumes on the target array. |

yes. you can move the hard drives from one MSA to another and the LUNs will
appear on the new MSA. This is do to Compaq's DTS technology (DAS to SAN). The metadata stored on the drives makes this possible. The Moojit. wrote in message oups.com...
