SAP LiveCache / MaxDB error


We are migrating from Solaris 10 to solaris10-Zone / Solaris-11 global configuration. While moving existing LiveCache to new h/w, we experiencing issues of Bad Page / Bad data / Bad log etc. Not sure, if this is due to new h/w and zone config. LiveCache is / Build25. I have gone over Solaris related LiveCache / MaxDB notes.

If any of you had similar issue, would appreciate, if you could share your experience.

      hi Deepak,

      The change is only Solaris-10 ---> Solaris-10 in zone inside Solaris-11 global. I doubt, if this requires any Livecache migration process. The restored data was LiveCache data consistency checked and off-line backup. We made sure, no data inconsistency in the backup.

      Unix team checked the disk verification on raw disks volume for data and log. We are not sure,if there any OS level settings causing the error.
