Hello Ray, you are running in a migration problem. The point is that the architecture of SAP DB 7.4 is not 100 percent compatible to 7.3, i.e. the system devspace is obsolete. In 7.4 the converter pages and the restart page are stored within the data volumes. Additional each 7.4 data and log volume contains a new Info page, which is located in front of the volume. This Info page is used to reduce the possibility of unauthorized configuration modifications. Finaly the layout of the log entries has changed and therefore the 7.3 log unusable in 7.4.
Your restart fails because the IOManager was not able to read the Info page. This is no suprise because the block on the data volume is occupied by an ordinary data page (7.3). 2002-11-20 06:41:23 0x28C ERR 0 Kernel Page check failed; algorithm: 7, calculated: 46102, header: 2, trailer: 2 2002-11-20 06:41:23 0x28C ERR 12 IOMan Bad page on Data volume 1 blockno 0 2002-11-20 06:41:25 0x28C ERR 0 Kernel Page check failed; algorithm: 7, calculated: 46102, header: 2, trailer: 2 2002-11-20 06:41:25 0x28C ERR 12 IOMan Bad page on Data volume 1 blockno 0 2002-11-20 06:41:27 0x28C ERR 0 Kernel Page check failed; algorithm: 7, calculated: 46102, header: 2, trailer: 2 2002-11-20 06:41:27 0x28C ERR 12 IOMan Bad page on Data volume 1 blockno 0 2002-11-20 06:41:29 0x28C ERR 25 IOMan Can not read info page from Data volume 1 <==== 2002-11-20 06:41:29 0x28C ERR 18196 DBCRASH vabort:Emergency Shutdown, IOMan_Volume.cpp: 274 2002-11-20 06:41:29 0x28C ERR 19999 BTRACE SymbolSearchPath: C:\Program Files\sapdb\indep_data\wrk\TSGDB;C:\PROGRAM FILES\SAPDB\DEPEND\pgm;C:\PROGRAM FILES\S SAP DB 7.4 offers two different ways to migrate from 7.3 to 7.4: - inplace migration - special save data cold and subsequent restore data Sorry for the inconvenience we made. At this time we have no spotlight for the 7.4 migration. We are working on it and will publish it as soon as possible.

Everything proceeded as normal, finished just fine, but when we go to start it, we get Msg: -24988 sql error [db_warm -f]; -8888,connection broken and the enclosed error trace. We were able to create a new 7.4 beta instance and import the data but had no success getting the updated instance running, and wondered if you had any clues as to this issue.
