Thanks for the details on configuring Ldoms in osc. We are not in a position to use any cluster software, hence I was looking for a tool that can move guest domain.You mentioned "Even if you do not use osc You will understand how to setup ldom for migration even if one hoSt is down..."Do you mean migration using "ldm migrate-domain ..." is possible even when source physical host is down. Could you elaborate please.ArjunOn Sat, Mar 5, 2011 at 10:26 PM, "Hung-Sheng Tsao (Lao Tsao 老曹) Ph.

I am looking for the ability to manually bring up guest domains on another host, within few minutes, when the source host (T5440) goes unavailable for any reason.

Please advise if you can think of another approach to achieve this. Thanks for your directions.If the ldom is hosted on share storage then afaik even the 1st host is unavailable One can bring up the ldom on the 2nd host This is how ha ldom work or ha app work Please read the Docs on oracle solaris cluster agent for ldom, Even if you do not use osc You will understand how to setup ldom for migration even if one hoSt is downArjun On Sat, Mar 5, 2011 at 6:33 PM, Laotsao <[email protected] <mailto:[email protected]>> wrote: Hope someone else can help you with the download But you can usE oracle cluster 3.3 is the latest with ldom now, ldom 2 also make migration easier, please see the Docs for requirement, firmware patches etc Sent from my iPad Laotsao On Mar 5, 2011, at 2:57 AM, Arjun YK <[email protected] <mailto:[email protected]>> wrote:I am looking for setting up LDoms as shown in http://blogs.sun.com/jb/entry/flying_ldoms But the, fldom tool mentioned there, is not available for download.
