EVA - Continuos Access

Hi, Does anyone have hands-on experience with the subject matter? The plan is to replicate from (7) EVA’s to (5) EVA’s over an OC-3/local connection. Besides the firmware being at the right levels are there any pros, cons, gotcha’s etc. Any info will be truly appreciated.

Zia,

CA is _INCOMPATIBLE_ with HBVS (Host Base Volume shadowing) which offers MUCH superior functionality in VMScluater environments.

Keith Parris has some good info on this - Keith, if you are monitoring - can you jump in?

Proost.

Have one on me (perhaps in May in Nashua?)

Zia,

I would also recommend using Hostbased Volume Shadowing in a VMS cluster environment.

Getting continuous access throughout a migration is well within its capabilities, as is increasing the sizes of the volumes. I presented a session on this at the 2005 HP Technology Forum, the notes are at http://www.rlgsc.com/hptechnologyforum/2005/1146.html

Done properly, migration is transparent to the users.
