ioinit cannot reassign a instance number

[Jdamian]

Hi.

In a N-class server I tried to reassign a instance number of an interface but ioinit failed and reported that the instance number was already assigned... but it is not true.

'ioscan -kfnC ext_bus' shows the instance numbers are: 0,1,2,13,14,15,16,17,18.

I want to reassign 13,14,... to 3,4,...

Then I created a file according to ioinit man pages:

0/10/0/0.1.21.0.0 ext_bus 4

I rebooted the system in single-user and ran:

ioinit -f file -r

but ioinit reports that instance number 4 is already assigned.

can anyone help me ?

where I wrote "I want to reassign 13,14,... to 3,4,.." I wanted to write "I want to reassign 13,14,... to 4,5,.."

The ioinit error messages is:

ioinit: Instance number 4 already exists for class ext_bus.
Line 1. 0/4/0/0.1.21.0.0 ext_bus 4


thanx in advance

hi,

Sometimes, slots remains used in the ionit files while they shouldn't. It seems to be your problem ... In this case, the only way to to what you want is to rebuild it completly :

1 - generate a new infile

ioscan -kfn | grep -e INTERFACE -e DEVICE | grep -v target | awk '{printf "%-40s %-20s %5s\n", $3, $1, $2}' and change all required instances

2 - mv /stand/ioconfig /stand/ioconfig.sav
mv /etc/ioconfig /etc/ioconfig.sav

3. shutdown -r

4. interrupt the boot process, boot pri, interact with ISL.

5. ISL> hpux -is

6. cd /stand
/sbin/ioinit -c
/sbin/ioinit -f infile

7. /sbin/reboot

Hi:

It sounds as if instance #4 was at one time valid and that this is being "remembered". There is a good procedural discussion of how to attack reassigning instance numbers *and* a tool to expose hidden values in the Software Recovery Handbook (chapter-14):

Thanx a lot, James and Jean-Louis.

James, in the chapter 14, a tool called "ioconfig2instance" is mentioned. Where can I find it ?

Thanx again

Hi (again):

To obtain the 'ioconfigtoinfile' tool, I believe you will need to call the Response Center.
