change Instance number of ext_bus

[Jurgen Ponds]

Hello

I have the following ext_bus instance numbering.

Class I H/W Path Driver S/W State H/W Type Description

ext_bus 50 1/2/0/0 c720 CLAIMED INTERFACE SCSI C895 Ultra2 Wide LVD

I want to change the Instance number of 49 and 50 to 10 and 11.
When I do an ioinit it tells me that the numbers 10 and 11 already exists, while they are not listed with ioscan.

The system is a HP9000/N4000 with HP-UX11.00.

How can I solve this issue?

Hello,

Create file 'infile' with the following info

0/8/0/0 ext_bus 10
1/2/0/0 ext_bus 11

Then execute the following command

ioinit -f infile -r

This commmand reboots the server immediatly, after the reboot the instance numbers has changed
