What are the steps needed in order to rebuild devices in 11.23?

Hi John:

If you mean special device files, then 'insf'. See the manpages.

insf -e

With the -e option, insf reinstalls the special files for pseudo-drivers and existing devices. This is useful for restoring special files when one or more have been removed.

Hi John,

if you mean rebuild "special device files" then do
$ ioscan
to discover new HW and then
$ insf -e

I know about ioscan and insf, but is there a way to cleanup or remove any unused devices files and rebuild the devices even if it requires a reboot. We are having issues after upgrading to 11.23 from 11.11. It gives us devices errors and wanted to know a way to total remove all devices except rootdg and rescan/rebuild.

Example: remove old non-existant disk devices.

ioscan -kfnC disk|grep NO_HW

rmsf -H HW_ADDR_FROM_ABOVE

Hi John,

with a reboot all devices are recreated from ground up. Did you really NOT reboot since upgrade?

And what error messages do you see exactly?
