I tried to remove some NetApp LUNs from a RHEL 4.6 system, and originally stale mappings remained in multipath -ll which I was not able to flush. In production instance, I am unable to remove the multipath mappings because the vg is missing. How can I deactivate a missing vg?
My test instance, I had the opportunity to return the test LUNs to service and was able to "vgchange -an" followed by a "multipath -f mpath1" which removed the mapings.
However, the four paths remain in my /dev/ heirarchy, and vgscan returns this for each of the devices that are no longer really there:
/dev/sdf: read failed after 0 of 4096 at 0: Input/output error
How may I remove these missing devices?
