does someone know, if it's possible to mirror (replicate) two identically configured VA 7400s? If yes, do I need special firmware or SAN management software to configure this replication?
Just use HP-UX mirroring - it works no problems - no extra software licensing required on the array - just a mirror disk license on the server. I believe that when using mirroring back block relocation should be turned back on (normally off for arrays).
Yes, Stuart is correct. There're no hardware mirroring capabilities. You can mirror VAs only using software. For windows you can create dynamic disks on the LUNs and use w2k built-in capabilities to create mirrored volumes. Looking forward to your questions I can say that VA and Autopath work with dynamic volumes, but business copy does not support them Eugeny
thank you for the info. Now we have two big problems: 1. We are working with Business Copy VA and 2. We are working with w2k cluster service, that doesn't support dynamic disks too.
Do you know any other solution for our problem (see also my reply to Stuart)
we successfully installed an W2k (Strech)Cluster (for disaster tolerance). We used Veritas Volume Manager. Whith this Software you can use Dynamic Disks in a MSCS. So Software Mirroring between two VA Arrays is possible. They dont even need to be identical.
