Reseting Device Files

[Robert-Jan Goossens_1 · Accepted solution]

Hi Pedro,

If you do not have data on any of the SymmetriX device/luns, just pull the fibre cables from the HBA's and, wait until they are all stale in ioscan and run "rmsf -x". Reattach the fibre cables and run insf.

Regards,

Hi,

I've unplugged the HBA cables, did rmsf -x, but the device files are still present:

Should I remove them with rmsf -H before plugging in the HBA cables?

Thks,

"Should I remove them with rmsf -H before plugging in the HBA cables? "

Yes

[Duncan Edmonstone]

Pedro,

Duplicate EMC device files on 11iv3 usually mean you don't have the correct director bits set on the FA.

Ensure SPC2 and OS2007 bits are set on the Symm

HTH

Duncan

[Hakki Aydin Ucar]

After detach the stated cables , did you try
insf -e ?

[Pedro Cirne]

Hi Duncan,

That's true, the flags were incorrect, my question was how to remove all the duplicate files:)

Pedro

[Pedro Cirne]

Thank you all!
