How to remove old HW from the system

[Has]

Hi,
EMC changed the tape devices to new one, but when I do ioscan -fnC tape I still get NO_HW for the old devices

Please check attachment.

What is the safe way to remove the old HW devices?

[Luk Vandenbussche]

with the command rmsf

To remove the device file
rmsf /dev/rmt/2m
rmsf /dev/rmt/2mn
rmsf /dev/rmt/..

to remove the HW/path

rmsf -H 13/0/2/1/0/4/1.105.8.255.1.3.0

I've removed the tapes , but I still having the following , which I coundn't remove them or change their status to be claimed.

ext_bus 10 13/0/2/1/0/4/1.105.8.255.1 fcd_vbus NO_HW INTERFACE FCP Device Interface
target 5 13/0/2/1/0/4/1.105.8.255.1.3 tgt NO_HW DEVICE

Remove also this hardware path
rmsf -H 13/0/2/1/0/4/1.105.8.255.1
rmsf -H 13/0/2/1/0/4/1.105.8.255.1.3

[Has]

# rmsf -H 13/0/2/1/0/4/1.105.8.255.1
WARNING: The specified hardware path is BUS_NEXUS/INTERFACE type.
This will remove all the devices connected to it.
rmsf: Specified hardware path has no devices

# rmsf -H 13/0/2/1/0/4/1.105.8.255.1.3
rmsf: Specified hardware path has no devices

But they are still there in ioscan with NO_HW status.

Hi

The only way to get rid of those is to do a reboot. If there is a new device on the same HW path, you have to use fcmsutil with replace_dsk option.
