Anybody knows what are those extra device files which get created when u assign the hitachi 9980v disk to HP ux 11.11.

Hi,

None of the extra device file wll get created, but if you are using HDLM (Hitachi dynamic Link Manager) one more device file will be created in /dev/dsk/chntmdo (here n,m and o will be according to lun number) same will be created in /dev/rdsk directory too.

This device file should be used while configuring LVM volumes.

But if i am not using HDLM and i dont want multipathing .Here in my case these extra device files carrying the description of "Hitachi Disk Subsystem".

Use rmsf to remove unwanted device files. These files may be recreated if you run insf without any options. So in the future you may want to use insf -H specifying a specific hardware path to restrict insf.

Thanks But these files may be required . I am not sure ,as i guess it is used by hitachi Subsystem or HP for Caching .

If it's simliar to EMC - they may be "gate keepers" and are needed - so don't remove!

If you do a diskinfo on them - what do you get back?
