Dear Forum Users,
i am new here please forgive my english!

first of all i´d like to tell you our history:

we have added a new harddisk to our alpha 4100 machine
true 64 unix 4.0, with a mylex raid controller!

this harddisk is now a "JBOD" - Single Harddisk!

- now i carried out MAKEDEV to re2
- in the /dev folder now i have devices re2a to re2h
and also rre2a to rre2h (raw devises i think?)

How can i create 2GB Chunks for use to an informix test-dbspace??
the chunks should be named so that i immediately now - this is a chunk!

please help me.

Hi,

Hi, Berli

Sorry, /dev/ronlineX are symbolics links or raw-devices ?
You want add one chunk on testdbs dbspace ?
Gustavo

/dev/ronlinex are raw-devices.

thats what i would like do create from the new disk!
I would like to create a raw-device called ronline11 with
2GB and add them to testdbs!

the new disk has 36GB - so i want do create 4 raw-devices,
can you help me! i am not certified at unix....

thx

Hi Berli,

Sorry, I'm not know on Alpha 4100.
Can you run man makedev ?.....
Makedev or seemed will have create one devise of block (/dev/name)and one device of carater (/dev/rname), You must select carater devices.
Once you create the raw-devices, must run:
chown informix:informix /dev/new_carater_devices.
chmod 660 /dev/new_caracter_devices.
Then as user Informix run ONMONITOR or utility onspaces -a for add chunks.

Gustavo.

Thank you - now it works!
if added the raw-devices which i created with the makedev utility (rre2a-h) to my dbspace!
no i am usually importing the database!
the next problem, while importing was the typically DBDATE problem - but now it works!
Thanks a lot.
