I would like to delete tape instances from 1 to 37.

What's the problem?

The devices are CLAIMED and ready to use.

Anyway, if you want to delete the device files, try for example

# rmsf -H 0/0/10/0/0.5.112.255.0.0.0

They will be re-created on next boot ...

[Vincent Lin_1]

# rmsf -H 0/0/10/0/0.5.112.255.0.0.0

I have deleted instance 39

# ioscan -M atdd -H 0/0/10/0/0.5.112.255.0.0.0 -I 1
ioscan: libIO error from io_insert_node: Node already exists or parameter error detected.

I can not rename the instance 39 to instance 1, because instance 1 already exist. I would like to know how to delete instance 1 without reboot.

# ioscan -M atdd -H 0/0/10/0/0.5.112.255.0.0.0 -I 39

I have no problem putting it back onto instance 39.

Are you trying to get your tapes so that they are in sequential order for the instance numbers?

I don't think there is an easy way to do that without rebooting and editing the /etc/ioconfig file.

Have a read through this document for details:
