Unanswered: Issue with the device activation while accessing database
Msg 840, Level 17, State 2:
Device 'uat_log1' (with physical name '/fnb/dbdevice1/uat_log1', and virtual
device number 33) has not been correctly activated at startup time. Please
contact a user with System Administrator (SA) role.
Msg 4001, Level 11, State 1:
Cannot open default database 'uatdb'.
Seems there is a device initilazation issue during last sybase server start up.
Possible reason is that the device don't have proper permissions for sybase user.
Please go through you ASE error log and search for the message for the device in question there.
Also check the physical file's permission which is related to the logical sybase device, get this fixed by OS admin and reboot the system.
This would also have caused your database offline, which are using the device in question.
