I tried to remove the paths with the command rmsf-k-H , but did not work. Check errors:

# rmsf -k -H 1/0/14/0/0.21.4.255.0
rmsf: Specified hardware path has no devices

# rmsf -k -H 1/0/14/0/0.2.23.0.38
WARNING: The specified hardware path is BUS_NEXUS/INTERFACE type.
This will remove all the devices connected to it.

Discs no more!

How can I identify the problem?

For SAN devices/LUNS

your message is indicating timeout for dev

pvdisplay dev
if IO timout is deault, then increase this to 90 secs


samething for the lvdisplay -v
increase the IO timeout to 90 secs.

Hi,

Why these many NO_HW is showing did you remove any storage from the running system ?

after giving "rmfs" reboot your server.
