One chunk file of my DBSpace was deleted carelessly. Thus, the informix
server gave the following message when I initilized it:

oninit: Cannot open chunk '/mydbfiles/dev/dbfile11'. errno = 2

How can I recover from this error?

Thanks in advance!

Are you saying that one of the db admins actually deleted a chunk ?

Yes! Because all of the chunk files have little avaiable space. So I
decided to add a new chunk to increase the size of DBSpace. But after
I have added a new chunk file, and then created some tables, I found that I have used up all the available size of the volumn which all my chunk files are in. So I decided to drop the chunk and create a new chunk in another volumn, I can't drop the chunk for I have created some tables on it, whereupon I deleted the chunk file. After this, I can't
start the database.

Thanks for any help.

recreate the linked chunk and restore from tape backup

You can only restore it if you have a physical backup of the dbspace or just reinitialize the database from scratch, then load the data backup afterwards.

if you have already created new link(or new added space) but you can't start database , you have to restore from backup
if your database can renew all data and you remember your database structure disk , use oninit -i and back to 0 then follow up you old step
