Hi,
you are absolute right. The problem is the content of the device
/dev/raw/raw20. The DB kernel expects to find the USM Page on
Data Devspace 10, offset 0, but he can find only a data index
page with the pageNo 1467308!
Page Header Page Trailer
page AC63160001070200...AC63160001070200
| | |_ Index Page
| |
| |_ Data Page
|
|_ PageNo 1467308
1. May be you modified the data base configuration file and you changed
the assignment of data devspaces and raw devices after you have restored
the hostfile?
2. May be your experimental kernel did not execute the write order of the USM PAGE?
3. May be you have a hardware problem ?
I prefer no. 1.
Regards,

Subject: In need of enlightenment...
We are running the OSDL dbt2-1tier test (on sapdb 7.3.0.25) and are
getting the failure below. This is running an experimental Linux kernel
(with a bug we feel), but we are stumped at what is causing it.
The failure occurs during the test run as we start to migrate a copy of
the database to the test machine (ie during the restore). With very
similar kernels the process works just fine, so I don't think it is our
kit.
I think the message means that the first page of /dev/raw/raw20 is read
and does not contain what the thread expects (some header, perhaps?), so
it assumes the disk is corrupt and errors out. If anyone can enlighten
us further, it would be greatly appreciated:
