Environment: ADSM Server V2R1M12 on OS/2

Problem: After halting the server, shutting down the machine and putting it
 to another location  dsmserv failed to start with a
failore ANR9999D dballoc.c... Zero bit count (sorry, I don't have the exact
 message available).

Next we tried a DSMSERV DUMPDB DEVCL=MANTAPE and it worked, but brought
some errors at the end about something it can't read.

After making a new database with DSMSERV INSTALL 1 E:\ADSMDBASE\LOG01.DSM 2
 E:\ADSMDBASE\DB01.DSM 500 E:\ADSMDBASE\DB02.DSM 500
we tried to load the database dump with DSMSERV LOADDB DEVCL=MANTAPE
VOL=DSM054 and we get the following messages

 ANR4039I LOADDB: Loaded 274000 database entries (cumulative).
 ANR4039I LOADDB: Loaded 275000 database entries (cumulative).

 ANR7837S Internal error TBCOL777 detected.


After several tries with new databases on different drives we decided to
restore an old database backup.
Creating a new database and starting DSMSERV RESTORE DB TODATE=TODAY we
get:

 ANR4639I Restored 45888 of 60530 database pages.
 ANR4639I Restored 49744 of 60530 database pages.

 ANR4640I Restored 60530 pages from backup series 6 operation 0.
 ANR0306I Recovery log volume mount in progress.

 ANR9999D icrest.c(1257): Unable to initialize database.
 ANR1364I Input volume DSM013 closed.
 ANR2032E RESTORE DB: Command failed - internal server error detected.

Then we upgraded the server to V2R1M14 --> the same.

Does anybody know, what's going on, how to get out of this situation ?
Why to make database backups, when I can't use them later on ?


Thanks
